It should be noted that the shaft sleeve 401 is installed on the mounting flange 102 and is fixed in position under the cooperation of the first fixing seat 101 and the second fixing seat 201. The shaft sleeve 401 protrudes from an outer side of the first fixing seat 101 and the second fixing seat 201 after being installed, so as to easily resist the swivel 501. The shaft sleeve 401 is generally sleeved with an elastic sleeve to facilitate the installation of the swivel 501 and increase friction. Generally, 20 or more Hall elements are arranged in the angle sensor 305 to improve the measurement accuracy. The connection and use methods of the main board 301, the display screen 720, and the angle sensor 305 are commonly used and general prior art, and will not be repeated here.

It should be pointed out that the rear cover 601 is rotatably clamped and mounted on the second fixing seat 201, and the first fixing seat 101 is provided with a reset notch 105, and the reset notch 105 is directly connected to the main board 301.

Specifically, as shown in FIG. 2, the back cover 601 is provided with a pressing plate 610, and the outer first button 611 and the outer second button 612 are arranged on the pressing plate 610. It also includes a back glue 710, the back glue 710 is provided with a through groove 711, the through groove 711 is matched with the display screen 720, the back glue 710 is installed on the upper surface of the display screen 720 and is fixed by transparent cover 701.

Specifically, as shown in FIGS. 6 and 7, there are four mounting flanges 102 and matching flange 203, four shaft sleeves 401 are provided, and the internal teeth 503 are provided on the lower end of the inner surface of the swivel 501, and the upper end of the inner surface of the swivel 501 is provided with a rolling surface 504 that matches with the shaft sleeve 401. In addition, the shaft sleeves 401 are arranged in a circular array and are arranged on the same horizontal plane.

The traditional rolling measuring instrument generally rotates around the central axis of the device, and the swivel of a single shaft sleeve and rotating shaft is prone to up and down deviation and rolling jam after long-term use. The stress in the rotation process is generally concentrated on a single shaft and sleeve, which is prone to damage, and the internal structure is complicated, replacement and maintenance are difficult, and the volume is large.

When in use, the friction ring 510 rolls on the surface of the object, thereby driving the swivel 501 to rotate. The swivel 501 drives the gear 303 to rotate through the internal teeth 503, and the angle sensor 305 is positioned on the number of turns and angles of rotation are recorded under the control of the main board 301, and output to the display screen 720. The measurement is controlled by using the first button 310 or the second button 311, such as resetting to zero, setting the starting point, and setting interruption. Point, set the end point and record data, etc. Compared with the traditional measuring instrument that rotates around the axis of the device, the structure is simpler and more concise, and the position restriction of the internal components is also smaller. At the same time, because of the four shaft sleeves 401, the structure is more stable and no aluminum alloy is needed to make the swivel 501, and the turbulence during the rotation will not cause the internal gears, sensors and other components to shift, the impact force received is absorbed by the four shaft sleeves 401, and the swivel 501 rotates smoothly and will not shift up and down under long-term use at the same time.

To sum up, the present disclosure uses the first fixing seat 101, the second fixing seat 201, the main board 301, the shaft sleeve 401, the display screen 720 and other components connected together through a clever structure to achieve stable and rapid measurement of the length of the surface of the object by rolling the swivel. With the cooperation of multiple shaft sleeves, the swivel rolls more smoothly, and the stability and stability of the overall structure are improved. The accuracy of the measurement enables the friction ring or the swivel ring to be made of plastic material to reduce cost and weight, and multiple buttons are used to control the measurement, and the display screen is used to intuitively output the measured information. The above greatly improves the use value of the disclosure.

The above-mentioned embodiments only express one or more embodiments of the disclosure, and their descriptions are more specific and detailed, but they should not be interpreted as limiting the scope of the disclosure. It should be noted that for those of ordinary skill in the art, without departing from the concept of the disclosure, several modifications and improvements can also be made, which all fall within the protection scope of the disclosure. Therefore, the protection scope of the disclosure shall be subject to the appended claims.
