A clamping groove 301 is formed on the inner wall of the protective sleeve 3. The clamping groove 301 matches the inclined plane at one end of the block 408. Through the setting of the clamping groove 301 and the block 408, the protective seat 2 and the protective sleeve 3 can be conveniently connected, improving the connection efficiency between the protective seat 2 and the protective sleeve 3;

[0025] A second spring 4081 is fixedly connected to the inner wall of the sliding block 407. One end of the second spring 4081 is fixedly connected to the block 408. The second spring 4081 is used to maintain the initial position of the block 408, and the second spring 4081 is used to provide a horizontal movement restoring force to the block 408. The sliding block 407 is used to ensure the stability of the horizontal movement of the block 408; A connecting rod 406 is provided at the bottom end of the sliding block 407. A sliding rod 405 is provided on one side of the connecting rod 406. An extrusion seat 404 is sleeved on the outer wall of the sliding rod 405. A moving seat 403 is provided at the bottom end of the extrusion seat 404. A moving column 402 is provided at the bottom end of the moving seat 403. The bottom end of the moving column 402 penetrates below the protective seat 2. A moving ring 401 is provided at the bottom end of the moving column 402. The downward movement of the moving column 402 can drive the moving seat 403 to move. The movement of the moving seat 403 can drive the extrusion seat 404 to move. The downward movement of the extrusion seat 404 can push the sliding rod 405 to move horizontally. The horizontal movement of the sliding rod 405 drives the connecting rod 406 to move. The movement of the connecting rod 406 drives the sliding block 407 to move;

[0026] The sliding block 407 is fixedly connected to the connecting rod 406 by bolts. The connecting rod 406 is welded to the sliding rod 405. The extrusion seat 404 is connected to the moving seat 403 by bolts. The moving seat 403 is connected to the moving column 402 by bolts. The moving column 402 is connected to the moving ring 401 by bolts. The downward movement of the moving ring 401 can drive the horizontal movement of the connecting rod 406 through mechanical transmission. A first spring 4031 is fixedly connected to the bottom end of the moving seat 403. The bottom end of the first spring 4031 is fixedly connected to the inner wall of the protection seat 2. And the first spring 4031 is located on one side of the moving column 402. The first spring 4031 is used to maintain the initial position of the moving seat 403 and the extrusion seat 404, and the first spring 4031 is used to provide a vertical movement restoring force to the moving seat 403. A limiting rod 4061 is sleeved inside the connecting rod 406. Both ends of the limiting rod 4061 are fixedly connected to the inner wall of the protection seat 2 by bolts. The limiting rod 4061 is used to support the connecting rod 406, and the limiting rod 4061 is used to ensure the stability of the horizontal movement of the connecting rod 406. An inclined through groove is formed in the inner wall of the extrusion seat 404. And the sliding rod 405 is cylindrical. The vertical movement of the extrusion seat 404 drives the movement of the inclined through groove. The inclined through groove squeezes the outer wall of the sliding rod 405, thereby driving the horizontal movement of the sliding rod 405.

[0027] Working principle: When in use, first place the protective sleeve 3 above the protection seat 2, and then move the protective sleeve 3 downward. The movement of the protective sleeve 3 drives the movement of the card slot 301. The inner wall of the protective sleeve 3 contacts one end of the card block 408, and thus squeezes the card block 408 to move towards the end close to the sliding block 407. The second spring 4081 is stressed and squeezed. When the card slot 301 and the card block 408 are at the same horizontal height, the second spring 4081 returns to its original state and drives the card block 408 to move in a reset manner. The card block 408 moves in a reset manner and engages with the card slot 301.

[0028] Secondly, when it is necessary to disassemble the protective sleeve 3, pull the moving ring 401 downward. The movement of the moving ring 401 drives the movement of the moving column 402. The movement of the moving column 402 drives the moving seat 403 to move downward. The first spring 4031 is stressed and squeezed. The movement of the moving seat 403 drives the movement of the extrusion seat 404. The movement of the extrusion seat 404 squeezes the sliding rod 405 to move towards the end away from the card block 408. The movement of the sliding rod 405 drives the movement of the connecting rod 406. The movement of the connecting rod 406 drives the movement of the sliding block 407. The movement of the sliding block 407 drives the movement of the card block 408. The card block 408 moves and separates from the card slot 301. Then the protective sleeve 3 can be removed.

[0029] Finally, by moving the moving ring 401 downward, the clamping block 408 can be driven to move horizontally through mechanical transmission, so that the clamping block 408 is separated from the clamping groove 301, and then the protective cover 3 can be disassembled. Compared with the traditional method of connecting the protective base 2 and the protective cover 3 through elastic cards, the protective base 2 and the protective cover 3 can be disassembled, which improves the convenience of using the sensor body 1 and also facilitates the quick replacement of the protective cover 3.

[0030] Through the settings of the clamping groove 301 and the clamping block 408, the protective cover 3 and the protective base 2 can be quickly connected, which improves the convenience of connecting the protective base 2 and the protective cover 3 and reduces the workload when connecting the protective base 2 and the protective cover 3.
