A positioning tooth block 19 is rotatably installed on the connecting shaft 18, and the bottom of the positioning tooth block 19 is clamped on the top of the positioning rack 17, and a positioning spring 20 is fixedly installed on one side of the positioning tooth block 19, and the positioning The end of the positioning spring 20 away from the positioning tooth block 19 is fixedly connected to the bottom of the threaded movable sleeve 8, and a pull rod 21 is arranged on the outer side of the movable bar 13, and a cross bar 22 is installed inside the pull rod 21 for sliding and passing through. Both ends of the cross bar 22 are fixedly connected to the outer side of the movable bar 13, and an L-shaped groove 23 is penetrated through the outer side of the support seat 1, and the end of the pull rod 21 away from the movable bar 13 is movable through the L-shaped groove 23 and extends to the outside of the support seat 1. During use, through the cooperation between the various structures of the positioning assembly 5, the threaded movable sleeve 8 can be positioned after adjustment and movement to prevent it from displacement, thereby ensuring that the movable clamp block 3 will not loosen, so that the limit switch can be tightly clamped between the fixed clamp block 2 and the movable clamp block 3.

[0026] Working principle: When working, first place the limit switch to be fixed on the top of the support seat 1, and make one side of the limit switch contact with the fixed clamp 2, then rotate the adjusting disk 7 to drive the adjusting screw 6 to rotate, and the adjusting screw 6 drives the threaded movable sleeve 8 to move, and the threaded movable sleeve 8 drives the positioning slide block 11 to slide inside the positioning slide groove 12, which can ensure that the threaded movable sleeve 8 achieves better stability when moving. At the same time, the threaded movable sleeve 8 drives the connecting shaft 18 to move, and the connecting shaft 18 drives the positioning gear block 19 to move. When the positioning gear block 19 moves, under the action of the toothed structure at the top of the positioning rack 17, the positioning gear block 19 will move upward. When the positioning tooth block 19 moves upward, it will squeeze the positioning spring 20, causing the positioning spring 20 to undergo elastic deformation. At the same time, the threaded movable sleeve 8 drives the sliding block 9 to slide inside the sliding groove 10, and the sliding block 9 drives the movable clamping block 3 to move. After the movable clamping block 3 moves to contact the limit switch, the adjusting disk 7 continues to be rotated so that the limit switch is fixedly clamped between the fixed clamping block 2 and the movable clamping block 3, and then the rotation of the adjusting disk 7 is stopped. At this time, the threaded movable sleeve 8 stops moving, and the positioning tooth block 19 stops moving accordingly. Under the rebound force of the positioning spring 20, the bottom end of the positioning tooth block 19 can be positioned and stuck in the corresponding tooth groove at the top of the positioning rack 17. The threaded movable sleeve 8 is positioned inside, thereby preventing the movable clamping block 3 from being displaced, ensuring the tightness of the limit switch in the clamping, and then the fixed clamping limit switch is processed. After the processing is completed, the pull rod 21 is pulled downward to drive the pull rod 21 to move downward inside the L-shaped groove 23, and the pull rod 21 is clamped at the bottom end of the L-shaped groove 23. At the same time, the pull rod 21 drives the movable bar 13 to move downward on the outside of the vertical rod 14 under the action of the cross bar 22. The movable bar 13 moves downward to squeeze the support spring 16, causing the support spring 16 to undergo elastic deformation. At the same time, the movable bar 13 drives the positioning rack 17 to move downward, and the positioning rack 17 moves downward to release the positioning tooth block 19 The limit switch is then positioned by rotating the adjusting disk 7 in the opposite direction to release the fixed clamping of the limit switch, so that the threaded movable sleeve 8 is reset. After the threaded movable sleeve 8 is reset, the pull rod 21 is pulled to release its positioning state inside the L-shaped groove 23. At this time, under the rebound force of the supporting spring 16, the movable bar 13 is reset and moved, and the movable bar 13 drives the positioning rack 17 to reset. Then the above operation is repeated to fix and clamp the limit switch in subsequent processing. In this way, the fixing fixture for processing the limit switch can achieve better fastening after clamping the limit switch during use, thereby improving the stability during processing, thereby achieving better practicality.
