The main platform 1 is also provided with a ruler in the length direction and the width direction to facilitate accurate movement of the positioning module 2.

[0029] like Figure 4As shown, the clamping assembly 3 includes a guide rail 13 and a clamping block 14. The guide rail 13 is symmetrically provided with flanges 17 in the length direction. The guide rail 13 is provided with a first limit block 15 at the bottom thereof that is clamped with the first epitaxial region 11. In this embodiment, the first limit block 15 is wedge-shaped and is provided in two groups. The guide rail 13 is provided with a second limit block 16 on both sides of the length direction and close to the second epitaxial region 12. The second limit block 16 and the clamping block 14 can work together to form a clamping limit with the second epitaxial region 12. In this embodiment, In the figure, the second limit block 16 is fixedly connected to the guide rail 13. The second limit block 16 is a rectangular connecting block, and a recessed groove for accommodating fasteners is provided in the middle thereof. The clamping block 14 and the end of the second extension area 12 are wedge-shaped. The second limit block 16 and the clamping block 14 are connected by fasteners, which can fix the position of the clamping assembly 3 on the main platform 1. When the position of the clamping assembly 3 needs to be adjusted, the displacement can be achieved by loosening the fasteners. The fasteners are arranged on the outside of the main platform 1 for easy operation by the staff.

[0030] The positioning module 2 is provided with a mounting seat 4 connected to the clamping assembly 3, and a sleeve assembly 5 is provided above the mounting seat 4. The upper end of the sleeve assembly 5 is detachably connected with a positioning seat 6 for fixing the car, and the positioning seat 6 is adjustable in the vertical direction.
