A driving motor 7 is provided on the mounting platform (3), and the power output end of the driving motor 7 is connected to the fixed part 4. The driving motor 7 and the three-dimensional position adjustment device 2 are existing mature technologies. This scheme is not specifically expanded without affecting the integrity of this scheme. The three-dimensional position adjustment device 2 drives the mounting platform 5 to move, so that the detection head 6 gradually rests on the thread of the threaded part to be detected.
[0015] Both ends of the extrusion plate 14 pass through the fixed cylinder 5. The lower end of the extrusion plate 14 is rotatably connected with a ball. The ball is located inside the fixed cylinder 5. The ball rests on the upper end surface of the movable plate 15.

The locking piece 16 and the locking groove 17 are clamped. When the locking piece 16 and the locking groove 17 are clamped, the anti-collision head 11 is limited and fixed. When the detection head 6 collides, the locking piece 16 disengages from the locking groove 17, and the anti-collision head 11 rotates in the connecting port 10 to buffer the impact force caused by the collision and avoid damage to the detection head 6. When the detection head 6 is away from the threaded part, the anti-collision head 11 is reset under the action of the counterweight 12, so that the detection head 6 remains in a vertical state.
