The outer wall of the limit screw 11 passes through and is threadedly connected with a fastening nut 14, and the position of the limit block 15 is fixed by the upward and downward movement of the thread of the fastening nut 14 on the limit screw 11.

[0032] Combination Figure 1-3 A replacement component is provided on the fixed component, and the replacement component includes a drive motor 12, and the drive motor 12 is located in the middle of the lower fixed cover 20 and the upper fixed cover 10. The front end of the drive motor 12 is fixedly connected with a rotating shaft 9, and the front end rotating shaft 9 is driven to rotate by starting the drive motor 12. The front end of the rotating shaft 9 is fixedly connected with a fixed sleeve 8, and the fixed sleeve 8 is driven to rotate during the rotation of the rotating shaft 9. The outer wall of the fixed sleeve 8 is penetrated and threaded with evenly distributed fastening bolts 18, and the output end of the fastening bolt 18 is rotatably connected with a clamping block 19, and the threaded rotation of the fastening bolt 18 on the fixed sleeve 8 drives the front end clamping block 19 to move forward.

[0033] Combination Figure 1A detection component is arranged inside the protective cover 2, and the detection component includes a reflector 3 and the reflector 3 is located inside the protective cover 2.
