After moving to the designated position, rotate the fixing bolt 16 so that the fixing bolt 16 abuts against the connecting plate 14, thereby fixing the position of the second sliding block 15. The second telescopic member 13 drives the connecting plate 14 to move longitudinally, thereby driving the detection pressure tube 20 to move longitudinally, and cooperating with the connecting pipe 25 to fix the part to be detected.
