The roller 21 can rotate by means of the first rotating shaft 22.

[0028] Refer to Figure 1 and Figure 3, a rotatable convex block 11 is provided in the card slot 7. The convex block 11 is fixedly connected to the outside of the rotating column 12. The convex block 11 rotates by means of the rotating column 12. Symmetrically fixed connections are provided on the outside of the rotating column 12 with stoppers 13. The roller 21 has a limiting effect on the stopper 13. When the rotating column 12 rotates, the stopper 13 presses on the outside of the roller 21. The roller 21 drives the support plate 23 and the bottom plate 14 to press down, and the hydraulic column 15 and the second spring 16 press down. When the stopper 13 no longer presses down on the roller 21, the hydraulic column 15 and the second spring 16 rebound, lifting the support plate 23 and the bottom plate 14 upwards.
