[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model uses a cross knife to squeeze the card cover in the card slot. After the card cover is subjected to force, the fixed block connected to the bottom thereof will be displaced in the notch of the vertical slot. At the same time, the spring cylinder and the spring assembly cylinder connected to the back of the fixed block are integrated. The spring cylinder is subjected to force and is displaced toward the inner cavity of the spring assembly cylinder, and the card cover is separated from the card slot, so that the front cover can be removed from the front end of the machine box. The structure is more optimized and the design is more reasonable. BRIEF DESCRIPTION OF THE DRAWINGS
