[0025] Working principle:

[0026] First, the high-pressure oil pipe body 2 is passed through the bucket-shaped threaded pipe 402 and the clamping block 401, and the rotating block 403 is manually rotated. The brick 403 drives the internal bucket-shaped threaded pipe 402 to rotate in the clamping block 401 in a threaded manner. The bucket-shaped threaded pipe 402 squeezes the clamping block 401, so that the clamping block 401 fixes the high-pressure oil pipe body 2;

[0027] Manually push the second mounting frame 6 to move on the slide 5 to adjust the position between the second mounting frame 6 and the high-pressure oil pipe body 2, manually rotate the threaded rod 7 on the second mounting frame 6, and the threaded rod 7 pushes the rubber plate 8 to squeeze the outer wall of the high-pressure oil pipe body 2 for detection;
