A slide groove is provided at the position where the inner cavity of the key cabinet body 1 is connected to the movable plate 403, and the inner wall of the slide groove is slidably connected to the bottom of the movable plate 403. The face recognition panel 2 recognizes the face and transmits the recognized face information to the face database. By comparison, the personnel information is ensured, and the background server is used to transmit a signal to the control module to control the cabinet door 3 to open and remove the device 4. The control motor 401 controls and drives the screw rod 402 to rotate. While the screw rod 402 rotates, it drives the movable plate 403 connected to the outer edge thread to move, and sends the key hanging on the hook 404 from the inner wall of the key cabinet body 1.

[0025] The blocking device 5 includes a tooth plate 501 and a baffle 504, and the tooth plate 501 drives the baffle 504 to rise and fall to block the key placement. The blocking device 5 also includes a driven gear 502. The inner wall of the tooth block of the tooth plate 501 is meshed with the gear teeth of the driven gear 502. The bottom of the driven gear 502 is rotatably connected to the inner wall of the key cabinet body 1.
