The platform B is provided with a sliding rail groove B, two clamping blocks are nested in the sliding rail groove B, and the clamping blocks are clamped to clamp a target part by rotating a threaded rod A into a threaded hole B on the platform B.

[0005] Further, a sleeve is sleeved on the lifting rod and fixed by a rotating knob. The sleeve is connected with the platform A through an axial steering shaft. The axial steering shaft is provided with a damping ball joint. The up-down inclination angle of the platform A is adjusted through the damping ball joint.

[0006] Further, a universal ball joint is arranged above the sliding rail to adjust the angle of the platform B.

[0007] Further, a bump-preventing rubber pad is attached to the surface of the clamping block to prevent damage to the part when the clamp platform clamps the part.
