The separated sides of the limiting blocks 10 on the left and right sides penetrate the bottom plate 8, so as to utilize the cooperation between the limiting blocks 10 and the limiting grooves 11 to clamp the base 3 and the two connecting parts 36, thereby facilitating the disassembly and assembly of the sensor body 1, and the two-way lead screw 21 penetrates the slide groove 25, and the tops of the limit plates 4 on the left and right sides are both in contact with the bottom wall of the cover plate 7, so as to facilitate the subsequent opening of the cover plate 7 and the maintenance of the parts on the inner wall of the bottom plate 8.

[0021] First, place the base 3 between the two connecting pieces 36 and mount it on the top of the receiving piece 2. Then, rotate the two-way screw 21 to drive the slider 6 to slide backward along the inner wall of the second slide groove 25. At this time, by utilizing the cooperation between the connecting frame 27 and the elastic connecting rod 5, push the limit plate 4 to both sides and move backward along the inner wall of the slide groove 1 9, and at the same time drive the limit blocks 10 on both sides to penetrate the bottom plate 8 and insert into the inner wall of the limit groove 11 to clamp the base 3 and the two connecting pieces 36.

The movable plate 22 is slidably connected to the middle part of the inner wall of the movable groove 20, and the top is fitted with the rear side of the bottom wall of the cover plate 7. The front end of the plug post 24 is inserted into the inner wall of the slot 12, so as to increase the stability of the assembly between the base 3 and the receiving part 2 by utilizing the connection between the plug posts 24 on both sides and the slot 12.

[0023] First, rotate the bidirectional lead screw 21 to drive the slider 6 to slide backward along the inner wall of the second slide groove 25. During the movement of the slider 6, the movable plate 22 will move forward synchronously along the inner wall of the movable groove 20, and at the same time drive the connecting plates 23 on both sides to move, thereby pushing the two plug posts 24 forward to insert into the inner wall of the slot 12 to improve the stability of the installation between the base 3 and the two connecting parts 36. When the sensor body 1 needs to be disassembled, reverse the bidirectional lead screw 21 at this time, thereby driving the slider 6 to slide forward along the inner wall of the second slide groove 25, driving the limiting blocks 10 on both sides to disengage from the limiting slot 11, and at the same time the movable plate 22 will slide backward, driving the plug posts 24 on both sides to disengage from the slot 12, and then the sensor body 1 can be removed.
