[0024] In one embodiment, the output end of the motor 401 is fixedly installed on the top of the support frame 2, one end of the threaded rod 402 is fixedly installed on the output end of the motor 401, and the other end of the threaded rod 402 is installed on the inner wall of the slide groove 3 through a bearing. The inner wall of the slider 403 is threaded onto the surface of the threaded rod 402, and the surface of the slider 403 is movably installed on the inner wall of the slide groove 3.
[0025] Specifically: The motor 401 is started by an external power source, which drives the threaded rod 402. The slider 403, which is threaded on the surface of the threaded rod 402, moves up and down on the inner wall of the groove 3, so that the device can be adjusted in height and make the device more perfect.
[0026] In one embodiment, the surface of the support frame 2 is provided with a limiting groove 201, and the number of limiting grooves 201 is two. A limiting block 501 is fixedly installed on one side of the bearing plate 5, and the number of limiting blocks 501 is two. The surface of the limiting block 501 is movably installed on the inner wall of the limiting groove 201.
[0027] Specifically: The limiting block 501, which is fixedly installed on one side of the bearing plate 5, is movably installed on the inner wall of the limiting groove 201 opened on the surface of the support frame 2, so that the slider 403 drives the bearing plate 5 to move up and down more stably, making the device more perfect.
[0028] In one embodiment, a support telescopic rod 15 is fixedly installed on the other side of the support plate 5. There are two support telescopic rods 15, and the other end of the support telescopic rod 15 is fixedly installed on one side of the support plate 7.
[0029] Specifically: The other end of the support telescopic rod 15, which is fixedly installed on the other side of the bearing plate 1 5, is fixedly installed on one side of the bearing plate 2 7, so that the electric telescopic rod 1 6 is more stable when it drives the bearing plate 2 7 to extend and retract, making the device more perfect.

[0031] Specifically: The two ends of the electric telescopic rod 21 are movably installed on the bearing plate 27 and the mounting plate 10. The four electric telescopic rods 211 are divided into two groups. By activating the electric telescopic rods 211 of different groups, the mounting plate 10 is driven to adjust the angle, making the device more convenient and faster to adjust the angle, and making the device more perfect.
[0032] In one embodiment, a housing 16 is fixedly installed on the top of the support frame 2, and a lower housing 17 is fixedly installed on the bottom of the bearing plate 5.
[0033] Specifically: After the device is used, the electric telescopic rod 6 is activated to retract the device.

The four electric telescopic rods 11 are divided into two groups. By starting different groups of electric telescopic rods 11... 11. The mounting plate 10 is adjusted at an angle, causing the sensors 12, 13, and 14 fixedly mounted on the other side of the mounting plate 10 to adjust accordingly. This makes angle adjustment more convenient and quick, allowing the device to adjust the position and angle of the sensors according to detection requirements, thus making the device more complete. After use, the electric telescopic rod 6 is activated to retract the device. The motor 401 is started by an external power source, which drives the slider 403 on the surface of the threaded rod 402 to rise, so that the device is retracted into the housing 16 fixedly mounted on the top of the support frame 2. Then, the lower shell 17 fixedly mounted on the bottom of the bearing plate 5 is embedded in the bottom of the housing 16, protecting the device when it is not in use and reducing the impact of the external environment on the device, thus making the device more complete.
