[0025] In actual use of the above structure, first, the splint 11 on the fixed block 1 is placed on the pipe to be inspected, and then the handle 10 is rotated so that the handle 10 drives the worm 17 to rotate, and the worm 17 drives the worm gear 16, and the worm gear 16 drives the bidirectional screw 13 to rotate, and the bidirectional screw 13 rotates to drive the moving block 14, and the moving block 14 drives the splint 11 so that the splint 11 is clamped on the outer wall of the pipe.
