[0002] The handle of the smart door lock is equipped with a fingerprint head, which is connected to the central control module of the smart door lock through a connecting line. When opening the door, the user needs to collect information through the fingerprint head and the central control module verifies the information. After the information is verified, the door can be opened by turning the door handle. However, when the handle is turned, the connecting line will shake, and the connecting line and the surrounding door lock mechanism will wear out, which will affect the service life of the connecting line.
