A limit bolt 4 is rotatably installed on the movable seat 3. A fixing block 5 is welded on one side of the fixed seat 1, and a fixing hole 6 is opened on the fixing block 5. A cavity 9 is opened inside the fixed seat 1, and an access control mechanism 10 is movably installed inside the cavity 9. A display screen 12 is fixedly installed on the access control mechanism 10, and a camera 13 and a button 11 are respectively installed on the top and bottom of the display screen 12. A chute 7 is opened on the top of the fixed seat 1, and a support mechanism 14 is fixed on the inner wall of the chute 7. One end of the support mechanism 14 is fixed with a slider 15. The support mechanism 14 is a support spring, and the support spring pushes the slider 15 to move to one side of the chute 7 to displace and return the movable seat 3 and shield and protect the access control mechanism 10.

[0021] In this embodiment, a threaded hole 16 is opened on the slider 15, and the threaded hole 16 cooperates with the limit bolt 4. A limit groove 8 is opened on the inner wall of the chute 7, and a limit block is movably installed inside the limit groove 8. The limit block is fixedly installed on the side of the slider 15. A reset mechanism 18 is fixed on the inner wall of the cavity 9, and one end of the reset mechanism 18 is fixed with a movable plate 17. The movable plate 17 cooperates with the access control mechanism 10. An opening 19 is opened on the side of the fixed seat 1, and a limit hole is opened on the side of the access control mechanism 10. The limit hole cooperates with the opening 19. One end of the fixing mechanism 2 is movably installed inside the limit hole. The reset mechanism 18 is a reset spring, and the reset spring pushes the movable plate 17 to move the access control mechanism 10, and one side of the access control mechanism 10 is disassembled and taken out from the fixed seat 1.

[0022] The device provides the required electrical energy for the electrical appliances inside the device through an external power supply.
