The first object 5 can be a rack, a chassis, a cabinet for drawers, a window frame or other objects; and the second object 6 can be a circuit board, a drawer, a window or other objects. FIG. 13A shows the quick release connecting device according to the first preferred embodiment of the present invention is movably assembled to the second object 6 via the pivot portion 22 of the fixing member 2. Meanwhile, the retaining section 12 of the actuating retainer 1 and the second push section 23 of the fixing member 2 are detachably engaged with two opposite sides of the first object 5, so that the second object 6 is located in and sidewardly movably connected to the first object 5 via the quick release connecting device. When it is desired to separate the second object 6 from the first object 5, as indicated by FIG. 13B, simply push the first push section 14 of the actuating retainer 1 with one hand, so that the actuating retainer 1 slides toward the fixing member 2 by a limited range to separate the retaining section 12 from one side of the first object 5. Then, as shown in FIG. 13C, utilize the principle of leverage to push the quick release connecting device for the fixing member 2 to rotate about the pivot portion 22, bringing the second push section 23 to push the other side of the first object 5 away from it. At this point, the second object 6 can be pulled to slide out of the first object 5. Finally, as shown in FIG. 13D, when the second object 6 is separated from the first object 5 and the first push section 14 is no longer subjected to a push, the elastic element 4 automatically pushes the actuating retainer 1 to slide relative to the fixing member 5 back to its original position.

FIG. 14A shows the quick release connecting device according to the second preferred embodiment of the present invention is similarly movably assembled to the second object 6 via the pivot portion 22 of the fixing member 2. Meanwhile, the retaining section 12 of the actuating retainer 1 and the second push section 23 of the fixing member 2 are detachably engaged with two opposite sides of the first object 5, so that the second object 6 is located in and sidewardly movably connected to the first object 5 via the quick release connecting device. When it is desired to separate the second object 6 from the first object 5, as indicated by FIG. 14B, simply push the first push section 14 of the actuating retainer 1 with one hand, so that the actuating retainer 1 rotates relative to the fixing member 2 by a limited angle to separate the retaining section 12 from one side of the first object 5. Then, as shown in FIG. 14C, utilize the principle of leverage to push the quick release connecting device for the fixing member 2 to rotate about the pivot portion 22, bringing the second push section 23 to push the other side of the first object 5 away from it. At this point, the second object 6 can be pulled to slide out of the first object 5. Finally, as shown in FIG. 14D, when the second object 6 is separated from the first object 5 and the first push section 14 is no longer subjected to a push, the elastic element 4 automatically pushes the actuating retainer 1 to rotate relative to the fixing member 5 back to its original position.

Please refer to FIG. 15, which is an exploded perspective view of a quick release connecting device 7 according to a third preferred embodiment of the present invention. The quick release connecting device 7 includes an actuating retainer 71, a fixing member 72 movably assembled to the actuating retainer 71, and pin connection means 3. The actuating retainer 71 includes at least one first push section 711, a body portion 712, and a retaining section 713 for detachably engaging with a first object 5 (not shown in FIG. 15). The fixing member 72 internally defines a receiving space 721 and includes a pivot portion 722 formed on an outer side of the receiving space 721. The body portion 712 is movably received in the receiving space 721, and the pivot portion 722 is used to movably connect to a second object (not shown in FIG. 15). The pin connection means 3 enables connection of the receiving space 721 of the fixing member 72 to the body portion 712 of the actuating retainer 71, such that the actuating retainer 71 and the fixing member 72 are movable relative to each other within a limited range. The quick release connecting device 7 according to the third preferred embodiment of the present invention can further include an elastic element 4, which is disposed in the receiving space 721 with an end pressed against an inner wall surface of the receiving space 721 and another opposite end against the body portion 712. In this manner, the elastic element 4 enables and controls the limited movement of the actuating retainer 71 and the fixing member 72 relative to each other, and can elastically push the actuating retainer 71 and the fixing member 72 back to their original positions.

In addition, the retaining section 713 can be in the form of a hook, a recessed section, a protruded section, a stepped section, a flat surface, a cambered surface, or a curved surface.

Please refer to FIG. 16, which shows a quick release connecting device 7 according to a fourth preferred embodiment of the present invention. In the illustrated fourth preferred embodiment, the pivot portion 722 (please also refer to the pivot portion 722 shown in FIG. 15) has a pivot member 723 movably mounted thereto for coupling with the second object 6. The pivot member 723 includes a shaft 724 movably assembled thereto. The pivot member 723 (or the fixing member 72) and the shaft 724 are assembled together via a second pin connection means 725. An elastic element 73 is fitted on around the pivot portion 722 or the pivot member 723 with an end pressed against (or inserted into) the pivot member 723 (or a structure corresponding to the pivot member 723, such as a hole or a slot, not shown in the drawing) and another end pressed against the fixing member 72 of the quick release connecting device 7. The pivot member 723 includes a coupling section 726 for screwing onto, snap-fitted on, expansion-fitted on, welded to or riveted to the second object 6. Further, the fixing member 72 includes a limiting section 727 and the pivot member 723 includes a corresponding limiting section 728. When the fixing member 72 is moved or rotated, the limiting section 727 and the corresponding limiting section 728 can limit or stop each other at a specific location. The actuating retainer 71 or the body portion 712 thereof includes a shoulder section 714 for limiting a distance by which the actuating retainer 71 or the body portion 712 is allowed to move into the receiving space 721. Alternatively, the shaft 724 can be integrally formed with the pivot member 723 or the pivot portion 722, or can be fixedly assembled to the pivot member 723 or the pivot portion 722 (not shown).

The limiting section 727 or the corresponding limiting section 728 can be a beveled member, a flat member, a stepped member, a recessed member, or a protrusion. When the quick release connecting device 7 is turned by a target angle, the limiting section 727 and the corresponding limiting section 728 stop or limit each other and the quick release connecting device 7 can not be moved or rotated any further. The target angle can be, for example, ranged from 15 to 345 degrees.

Further, being driven by the elastic element 73, which can be a spring providing a twisting force, the quick release connecting device 7 can automatically turn within an angle limited by between the limiting section 727 and the corresponding limiting section 728 to achieve an elastic restoring motion, or an elastic releasing motion, or an elastic fastening motion.

The quick release connecting device 7 can also be driven by the elastic element 73, which provides a twisting force, to float within a range limited by between the limiting section 727 and the corresponding limiting section 728, including horizontally linear floating, vertically linear floating, or pivotal floating. Herein, a horizontally linear floating amount and a vertically linear floating amount of the quick release connecting device 7 refer to a distance by which the fixing member 72 is horizontally and vertically linearly movable relative to the pivot member 723, respectively; and a pivotal floating amount of the quick release connecting device 7 refers to an angle or a distance by which the fixing member 72 or the actuating retainer 71 is pivotally turnable between two different angularly spaced positions (not shown in FIG. 16).

In addition, the first push section 711 can be in the form of a post, a hole, a recessed member, a protrusion, a retaining member, a stepped member, an anti-slide member, a flat member, a cambered member, or a hooking member.

Please refer to FIG. 17, which shows a quick release connecting device 7 according to a fifth preferred embodiment of the present invention. In the illustrated fifth preferred embodiment, the actuating retainer 71 of the quick release connecting device 7 internally defines a receiving space 710, and the fixing member 72 includes a body portion 720 movably received in the receiving space 710; and the pin connection means 3 enables connection of the receiving space 710 of the actuating retainer 71 to the body portion 720 of the fixing member 72, such that the actuating retainer 71 and the fixing member 72 are movable relative to each other within a limited range.

Please refer to FIGS. 18 and 19, which show a quick release connecting device 7 according to a sixth preferred embodiment of the present invention. In the illustrated sixth preferred embodiment, the first object 5 and the second object 6 can be integrally formed, assembled together, or two independent objects; the second object 6 can be assembled to a fourth object 9 to form a modular object; or the quick release connecting device 7 and the second object 6 can be assembled together to form a module with an elastic element 73a pressing an end against the fixing member 72 of the quick release connecting device 7 and another end against the second object 6, such that the fixing member 72 under a spring force of the elastic element 73a is either automatically sprung back to its original position or limited to a fixed position. The fixing member 72 includes a second push section 729 having a first push part 7291 and a second push part 7292. The first push part 7291 or the second push part 7292 can be pressed against a third object 8. The pressing of the second push section 729 against the third object 8 causes a lever displacement, a rotational displacement or a limiting displacement of the quick release connecting device 7, so as to release, fasten, forward move or backward move the quick release connecting device 7. Alternatively, the first push part 7291 or the second push part 7292 can also be displaced by pressing them against the third object 8. The second object 6 includes a limiting section 61 for limiting a distance or an angle by which the second push section 729 can be moved or rotated, respectively. Or, in practical use of the quick release connecting device 7 according to the sixth preferred embodiment, the first push part 7291 and the second push part 7292 can be first subjected to a rotational or a non-rotational displacement to be located at a proper position in front of or behind or at a middle of a position on the third object 8 that is to be pressed against or interfered with, so that the first push part 7291 or the second push part 7292 of the second push section 729 having been rotationally or non-rotationally displaced can press against or interfere with the third object 8, enabling the quick release connecting device 7 to be released, fastened, forward moved or backward moved due to a lever displacement, a rotational displacement or a limiting displacement thereof.

In addition, the second push section 729 can be in the form of a protruded section, a recessed section, a through bore, a stepped section, a flat section, a cambered section or a curved section.

Further, when operating the first push section 711 of the actuating retainer 71 to compress the first push section 711 toward the fixing member 72, an overall travel of the quick release connecting device 7 is shortened, enabling the retaining section 713 to separate from the first object 5 while pulls the second object 6.

Further, the elastic element (not shown) is disposed in the receiving space 710 with an end of the elastic element pressed against an inner wall surface of the receiving space 710 and another opposite end against the body portion 720. In this manner, the elastic element enables and controls the limited movement of the actuating retainer 71 and the fixing member 72 relative to each other, and can elastically push the actuating retainer 71 and the fixing member 72 back to their original positions. That is, the seventh preferred embodiment can achieve the same effect as the fifth preferred embodiment.
