[0034] In the embodiments of the present invention, please refer to Figure 5 and Figure 6The auxiliary device 3 includes a fixed block 31, which is slidably connected to the supporting device 13. Both ends of the side of the fixed block 31 close to the supporting device 13 are fixedly connected with a connecting block 32, which is a rubber block. The inner walls of the two connecting blocks 32 are movably penetrated by a same limiting rod 33, and one end of the arc surface of the limiting rod 33 is threadedly connected with a threaded ring 34. The side of the fixed block 31 away from the supporting device 13 is fixedly connected with a contact block 35, and the side of the contact block 35 away from the fixed block 31 is fixedly connected There is a cleaning plate 36. When the roller 11 is used to contact the ground, the dirt on the ground will adhere to the surface of the roller 11.

After adjusting to a suitable position, the telescopic rod 203 is stuck in the inner wall of two fixing rods 205, so that the adjusting plate 204 can be fixed. Therefore, the height of the entire wheeled distance meter body 1 can be adjusted by sliding the adjusting rod 202 on the adjusting slot 206, so that the tall worker can use the wheeled distance meter. The distance meter body 1 uses two adjustment plates 204 to contact the support device 13, and the auxiliary block 210 installed on the adjustment plate 204 can increase the adjustment speed of the adjustment plate 204 on the support device 13. When the handle 14 is driven to connect with the connecting ring 207 by the screw 208, the protection pad 209 installed on the connecting ring 207 can protect the surface of the handle 14 to prevent the connecting ring 207 from damaging the surface of the handle 14 when the handle 14 contacts the connecting ring 207. The adjustment rod 202 made of titanium alloy is relatively hard. When it contacts the adjustment groove 206, the surface of the rod is also less likely to deform, and the service life is enhanced.

[0036] When the roller 11 is used to measure the distance on the ground, the cleaning plate 36 is first connected to the surface of the roller 11, and then the fixing block 31 is brought into contact with the supporting device 13, and the limiting rod 33 is inserted into the two connecting blocks 32, and the threaded ring 34 is rotated on the limiting rod 33. The two connecting blocks 32 are squeezed by the threaded ring 34 rotating on the limiting rod 33, so that the entire auxiliary device 3 can be fixed on the supporting device 13. When the roller 11 moves, the cleaning plate 36 can be attached to the roller 11. Cleaning the dirt can effectively improve the accuracy of the roller 11 in distance measurement. When using the cleaning plate 36 to clean the dirt on the roller 11, the scraper 37 installed on the cleaning plate 36 can scrape off larger dirt, thereby improving the cleaning effect of the cleaning plate 36 on the roller 11. When rotating the threaded ring 34 on the limit rod 33, the anti-slip groove 38 opened on the screw 208 ring can increase the friction between the hand and the threaded ring 34, thereby improving the efficiency of rotating the threaded ring 34 on the limit rod 33.
