A top button 704 is provided on one side of the button block 7. A slide groove 701 is provided in the button block 7. A slide rail 702 is installed on the side wall of the mounting bracket 8. The slide groove 701 is installed on the slide rail 702. The button block 7 is slidably connected to the slide rail 702.

[0037] The round button 603 is installed on the outer side of one end of the zeroing frame 9. The zeroing frame 9 is equipped with a dial shaft 602 and a lower shaft 901. The lower shaft 901 is installed on the mounting bracket 8. Both ends of the lower shaft 901 are equipped with lower shaft torsion springs 902. The zeroing frame 9 is also equipped with three equidistant top blocks 903, which are located on the outer side of the cam 303.

[0038] The working principle of this invention: This invention can be installed on the roof of a vehicle, and the flexible cycloid 101 and flexible cycloid 2 102 extend outward from the vehicle. When the vehicle is driving close to the edge, the flexible cycloid 101 and flexible cycloid 2 102 contact the pole to be counted and drive the cycloid 1 to swing around the fulcrum boss 107. As a result, the cycloid 1 drives the lever 2 to rotate, which causes the pawl 203 to actuate the ratchet 205. This causes the counting wheel 3, the counting gear 4, the dial gear 5, and the dial 6 to rotate and count. The spring 106 in the groove of the cycloid slide 105 buffers the impact force of the flexible cycloid 101 and flexible cycloid 2 102 hitting the pole. The main body of the flexible cycloid 101 and flexible cycloid 2 102 has a certain degree of flexibility and is not easy to break. Moreover, the flexible cycloid 101 and flexible cycloid 2 102 can be easily removed from the cycloid slider 104 for replacement.

[0039] The ratchet 205 used in this invention can drive the units counting wheel 304 to rotate. Since the ratchet 205 has only ten teeth, it can only rotate one-tenth of a circumference at a time. Simultaneously, the limiting block 103 also restricts the swing amplitude of the lever 1, thus ensuring that the lever 2 only swings a specific amplitude. Therefore, the pawl 203 drives the ratchet 205 to rotate only one-tenth of a circumference. The units counting wheel 304, connected to the ratchet 205, also rotates one-tenth of a circumference at a time. And when the units counting wheel 304 has completed its rotation… One week later, the carry-in dial 302 comes into contact with the carry-in dial 604 and moves the carry-in dial 604 one-tenth of a circle. As a result, the tens digit dial gear 501, the tens digit counting wheel gear 401, and the tens digit counting wheel 305 also rotate one-tenth of a circle, realizing the carry-in to the tens digit. Similarly, the carry-in dial 605, the hundreds digit counting wheel gear 402, the hundreds digit dial gear 502, and the hundreds digit counting wheel 306 can also realize the carry-in to the hundreds digit. This invention uses a mechanical structure for counting and carrying, which has high reliability.

[0040] The button block 7 and zeroing frame 9 used in this invention can quickly zero out the measured data. The measured data is displayed in the display frame 801. If it is necessary to clear the data, the top button 704 can be pressed, so that the inclined surface 703 on the button block 7 presses the round button 603 to offset, thereby causing the zeroing frame 9 to rotate around the lower axis 901 and bring the top block 903 close to the cam 303. The inclined surface on the top block 903 presses against the cam 303, causing the three equidistant cams 303 to deflect uniformly to the same position, thereby causing the units digit counting wheel 304, tens digit counting wheel 305, and hundreds digit counting wheel 306 to also deflect, thereby causing the numbers in the display frame 801 to rotate and uniformly return to zero. After zeroing, the lower axis torsion spring 902 resets the zeroing frame 9.

[0041] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
