[0026] Here, the diameter of the inside of the storage frame 201 is consistent with the diameter of the second rotating disk 205, the diameter of the third rotating disk 207 is consistent with the diameter of the internal hole of the fixing ring 206, and the thickness of the fixing ring 206 is consistent with that of the fixing ring 206. Here, the front of the fourth rotating disk 208 is fixedly connected to the mounting plate on the back of the detection body 3. By rotating the detection body 3, the fourth rotating disk 208 is driven to rotate, and at the same time, the second rotating disk 205 is driven to rotate inside the storage frame 201, and then the first rotating disk 204 is rotated backward, thereby driving the threaded rod 203 to rotate, so that the threaded rod 203 is pressed against the second rotating disk 205, thereby achieving the purpose of conveniently adjusting the use angle of the detection body 3 of this device.

[0027] A detection body 3 is installed in front of the angle adjustment mechanism 2 , and a clamping mechanism 4 is provided behind the mounting plate 1 .

[0028] The clamping mechanism 4 includes a first clamping block 401, a second clamping block 404, and two groups of mutually symmetrical screws 407.

[0033] Working principle: When assembling the device, the first clamping block 401 and the second clamping block 404 are clamped on the outer surface of the tightening rod 501, and then the output ends of the two sets of mutually symmetrical screws 407 are controlled to pass through the through holes 406 in sequence and be threadedly connected to the inside of the second threaded hole 403, so that the device can be quickly assembled, and the portability of the device is achieved. When fixing the device, by controlling the two mutually symmetrical tightening blocks 504 to rotate left, the two mutually symmetrical threaded columns 503 are driven to rotate left, and the two mutually symmetrical threaded columns 503 are driven to move away from each other, so that the deposit of the device can be fixed inside the pipe, achieving the purpose of convenient fixing of the device. When the observation angle of the detection body 3 needs to be adjusted, the detection body 3 is rotated, thereby driving the fourth rotating disk 208 to rotate, and at the same time driving the second rotating disk 205 to rotate inside the storage frame 201, and then the first rotating disk 204 is rotated backward, thereby driving the threaded rod 203 to rotate, so that the threaded rod 203 is pressed against the second rotating disk 205, achieving the purpose of conveniently adjusting the use angle of the detection body 3 of the device.
