An angle groove 302 is provided at the lower end of the limiting column 3. There are four groups of limiting columns 3 that can be close to each other and wrapped around the four corners of the sensor, so that the position of the sensor is fixed to prevent the position from changing due to vibration during use.

The gear column 402 is fixedly connected to the outer surface of the core shaft 401. The gear column 402 is meshed with the propulsion frame 6. The torsion disk 403 is fixedly connected to the top of the core shaft 401. When the central shaft 4 rotates, the gear column 402 can push the propulsion frame 6 to move and the central shaft 4 can drive the extrusion disk 5 to rotate.

[0028] The extrusion plate 5 is rotatably connected to the guide plate 2, and the extrusion plate 5 is sleeved on the outside of the limit column 3. The inner side of the mounting shell 1 is slidably connected with a propulsion frame 6, and the lower end of the propulsion frame 6 is fixedly connected with a clamping plate 7, and the propulsion frame 6 is meshed with the central axis 4. The propulsion frame 6 is composed of a slide frame 601, a ratchet bar 602 and a rack plate 603. The slide frame 601 has an "N" shape. The lower end of the slide frame 601 is fixedly connected to the clamping plate 7, and the upper surface of the slide frame 601 is fixedly connected with a ratchet bar 602.

The top tooth 11 can lift the positioning frame 9 by squeezing, so that the propulsion frame 6 can move in the opposite direction.

[0031] Working principle: When installing the sensor, first place the sensor at the center of the clamping plate 7, and drive the core shaft 401 to rotate by rotating the torsion disk 403, so that the gear column 402 rotates and pushes the rack plate 603 to move, so that the slide frame 601 slides toward the center, and the sensor is clamped by the clamping plates 7 that are close to each other. The extrusion disk 5 is driven to rotate by the rotation of the core shaft 401, so that the extrusion disk 5 rotates and pushes the limit column 3 to slide on the inside of the guide disk 2, and the limit column 3 can approach to limit the position of the sensor. After the push frame 6 slides, the spring 8 pushes the positioning frame 9 close to the ratchet bar 602, so that the position of the push frame 6 is fixed and will not move in the opposite direction to lock and fix the sensor position. When disassembly and replacement are required, press the top teeth 11 on both sides to make the pressing block 111 squeeze the pressing spring 112 and squeeze the positioning frame 9 at the same time, so that the positioning frame 9 drives the clamping piece 901 to rise and disengage from the ratchet bar 602, and the sensor is released by rotating the torsion disk 403 in the opposite direction.
