[0002] Access control is a security system used to control the entry and exit of people and vehicles. It usually consists of an electronic door lock and a card reader, which can verify identity by swiping a card, password, biometrics, etc. Access control devices can be set up at the door, window, elevator and other locations of a building to protect property and personnel safety. Access control devices have been widely used in modern society and are one of the important tools to ensure people's safety.

[0003] At present, in the prior art, a Chinese patent with announcement number CN218996080U discloses an access control device, which pre-presses the finger on a cleaning cotton block before fingerprint unlocking to clean the dust or grease on the finger, and then places the finger on the fingerprint unlocking area on the access control host to ensure that the unlocking area of ​​the access control host is cleaner and the unlocking can be kept accurate for a long time. However, in actual use, the device lacks convenience due to the cumbersome installation process of the access control host. This not only increases the installation time and cost, but may also lead to improper installation and affect the normal use of the access control system. In view of this, we propose an access control that is easy to install. Utility Model Content
