Each side of the screw block 4 that is close to the rotating shaft 5 has a hexagonal groove 6. Each screw block 4 has a hexagonal sliding groove 7 on its inner wall. Each hexagonal sliding groove 7 is slidably connected to a limit block 8. Each limit block 8 is used in conjunction with the corresponding hexagonal sliding groove 7. Each screw block 4 is threadedly connected to a bolt 9. The bolt 9 is rotatably connected to the corresponding limit block 8.

[0031] Two levels 20 are mounted on the top of the measuring instrument 19. A U-shaped plate 21 is fixedly connected to the side of the measuring instrument 19 near the lens. A groove 30 is opened on both sides of the U-shaped plate 21. A slider 22 is slidably connected inside the groove 30. A moving plate 23 is fixedly connected between the two sliders 22. A cleaning plate 24 is rotatably connected to the side of the moving plate 23 near the measuring instrument 19.

[0032] Two springs 27 are fixedly connected between the inner wall of the U-shaped plate 21 and the movable plate 23. A drive motor 25 is installed on the side of the movable plate 23 away from the cleaning tray 24. A first handle 26 is fixedly connected to the outer side of the movable plate 23 and outside the drive motor 25.

[0033] The top of the mounting base 1 and the corresponding first slide groove 2 are provided with a second slide groove 11. The interior of the second slide groove 11 is rotatably connected to a rotating rod 12. Both ends of the rotating rod 12 extend into the interior of the first slide groove 2 and are fixedly connected to a second conical wheel 14.

[0036] Working principle:

[0037] In use, turning the handle 18 causes the fourth conical wheel 16 to rotate. Since the fourth conical wheel 16 meshes with the third conical wheel 15, the third conical wheel 15 will rotate accordingly, thereby causing the rotating rod 12 to rotate. When the rotating rod 12 rotates, the second conical wheels 14 at both ends will drive the first conical wheel 13 to rotate, thereby causing the threaded rod 3 to rotate within the first sliding groove 2. The rotation of the threaded rod 3 will cause the screw block 4 to move within the first sliding groove 2. Through the connecting action of the connecting rod 10, the height of the measuring instrument 19 can be adjusted.

[0038] When it is necessary to adjust the tilt angle of the measuring instrument 19, rotate the bolt 9. The bolt 9 will push the limit block 8 to slide in the hexagonal groove 7. The limit block 8 cooperates with the hexagonal groove 6. When the limit block 8 is inserted into the hexagonal groove 6, the rotating shaft 5 is fixed. When the limit block 8 slides out of the hexagonal groove 6, the rotating shaft 5 can rotate. After releasing the rotating shaft 5, the tilt angle of the measuring instrument 19 can be adjusted by rotating the connecting rod 10. After adjustment, the bolt 9 is used to push the limit block 8 into the hexagonal groove 6 to fix the rotating shaft 5 and realize the adjustment of the tilt angle.

[0039] Hold the first handle 26 and push the moving plate 23 along the irregular groove 30 to bring the cleaning plate 24 close to the lens of the measuring instrument 19; start the drive motor 25, and the output shaft of the drive motor 25 drives the cleaning plate 24 to rotate to clean the lens; the spring 27 can play a buffering role during the cleaning process, so that the cleaning plate 24 fits more tightly with the lens and improves the cleaning effect.
