A fixed bearing 62 is fixedly installed on the outer surface of the connecting rod 61. The outer surface of the fixed bearing 62 is fixedly connected to the inside of the workbench 1. When the threaded rod 6 rotates, it controls the movement of the sliding card plate 12, and the fixed bearing 62 ensures that the threaded rod 6 can maintain stable rotation.

[0025] In order to facilitate the control of the horizontal movement of the movable placement platform 13, the second gear 5 is fixedly installed on the outer surface of the right end of the threaded rod 6, the outer surface of the second gear 5 is engaged with the outer surface of the first gear 4, and the outer surface of the workbench 1 is slidably connected to the movable placement platform 13. The lower surface of the movable placement platform 13 is fixedly connected to the upper surface of the sliding card plate 12. The first gear 4 drives the second gear 5 to rotate, so that the threaded rod 6 rotates, and the sliding card plate 12 drives the movable placement platform 13 to move horizontally.

[0026] The second motor 3 is fixedly mounted inside the upper end of the workbench 1, and the driving bevel gear 7 is fixedly mounted on the rotating shaft of the second motor 3.
