A card slot 12 is provided on the upper surface of the front shell 1, and the rotating block 22 is movably inserted into the inside of the card slot 12. The rotating block 22 cooperates with the card slot 12. When the host is installed, the rotating block 22 rotates from a vertical to a horizontal state so as to fit with the inside of the card slot 12 to complete the limiting of the back plate 2.

[0023] Specifically, a rotating shaft 23 is rotatably connected inside the back plate 2, and the rotating block 22 is fixedly connected to the surface of the rotating shaft 23. Mounting grooves 25 are opened on both sides of the back plate 2 near the rotating block 22, and a torsion spring 24 is fixedly installed inside the mounting groove 25. The other end of the torsion spring 24 is fixedly connected to the surface of the rotating block 22.

[0024] In the embodiment of the present invention, through the cooperation between the rotating shaft 23 and the torsion spring 24 , when the main unit is installed, the rotating block 22 can be rotated from a vertical state to a horizontal state under the action of the torsion spring 24 .

[0035] When installing the host, first move the rods 13 on both sides out of the sockets 26, push the back panel 2 upward, and install the host inside the front shell 1. While the back panel 2 moves upward, the rotating block 22 rotates from a vertical state to a horizontal state with the cooperation of the torsion spring 24 and the rotating shaft 23. After the host is installed, the back panel 2 moves to its initial position, and the horizontal rotating block 22 fits in the card slot 12 to limit the back panel 2 once. The T-block 21 slides inside the T-slot 11, and the socket 26 moves to the position of the rod 13. The rod 13 is reinserted into the socket 26 to limit the back panel 2 for a second time.
