The first The second motor 310 drives the second screw 309, and the second screw 309 drives the moving block 308 to move, so that the placement table 106 can be adjusted to a suitable position. The cross block 313 and the cross bar 316 can improve the stability of the placement table 106 when moving. The shielding plate 314 can shield the strip groove 315 and the moving groove 312, so as to prevent impurities from entering and affecting the movement of the moving block 308 and the cross block 313.

[0049] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
