[0026] like Figure 1-3 As shown in Figure 5, the bidirectional clamping assembly 2 includes a slide groove 6, which is symmetrically arranged at the edge of the table top of the main platform 1. A front-to-rear symmetrical slider group 7 is slidably arranged in the slide groove 6, one group of which is provided with a double-thread screw 8, which threads through the slider group 7 and the end is rotatably connected to the end of the slide groove through a bearing, and another group of slide grooves 6 is provided with a slide rod 9, which slides through the slider group 7. A motor seat 10 is fixed to the side of the main platform 1, and a motor 11 is fixed to the motor seat 10. The output end of the motor 11 is fixed to the double-thread screw 8. A clamp plate 12 is fixed to the top of the slider group 7, and a polyurethane protective layer 13 is fixed to the clamp plate 12, which has good wear resistance and will not scratch the surface of the plate. The cross-section of the slider group 7 and the slide groove 6 is trapezoidal, which plays a limiting role.

[0027] like Figure 1-4As shown, the adsorption component 3 includes a fixed column 14, which is evenly fixed to the bottom of the main platform 1, and the bottom of the fixed column 14 is fixed to the adsorption bin 15. An opening 16 is provided at the center of the top of the main platform 1, and the opening 16 is symmetrically arranged in two groups. A suction pipe 17 is provided on the top of the adsorption bin 15, and the other end of the suction pipe 17 extends into the opening 16 and is flush with the main platform 1. A negative pressure motor 18 is provided in the adsorption bin 15, and a sealing ring 26 is provided on the top of the suction pipe 17.
