[0023] The spring 9 is provided so that the two cotton sleeves 5 can expand when under pressure, thereby facilitating the insertion of the IC card.

[0024] A magnet is embedded in the middle front position of the bottom inner wall of the protection frame 1, and a metal block that can be attracted by the magnet is embedded in the bottom wall of the cover plate 2.

[0025] When the cover plate 2 is closed, the cover plate 2 can be fixed by adsorbing the metal block and the magnet.

[0026] The front and rear walls of the moving block 8 are both equipped with sliding blocks that match the sliding groove 7, and the moving block 8 is slidably connected to the sliding groove 7 via the sliding blocks.

[0027] Installation components 3 are provided on both sides of the protective frame 1, and the installation components 3 include a support block 10 and a docking sleeve 13.
