[0002] A smart lock is a door lock that adds electronic control functions to a traditional mechanical lock. It is unlocked through identity authentication using biometrics, password keyboards, Bluetooth adapters, network functions, etc. The core of a smart lock lies in its security and convenience. Compared with traditional mechanical locks, smart locks are usually equipped with lock cylinders with higher security levels, such as C-level lock cylinders, which have excellent performance in corrosion resistance, impact resistance, durability, etc., and the unlocking time is theoretically more than 10 minutes. At the same time, smart locks also have a variety of alarm functions, which further enhances security.

[0006] Furthermore, the mounting hole includes a threaded hole and a positioning hole, a through hole is provided in the middle of the handle head, and a bolt passes through the through hole and engages with the threaded hole to achieve connection and fixation of the handle and the handle head.

[0007] Furthermore, a plurality of grooves are provided on the positioning hole, and a plurality of bosses corresponding to the plurality of grooves are provided on the handle head, and the bosses are inserted into the grooves.

[0008] Furthermore, a lead hole is arranged on the side of the mounting hole, the lead hole extends from the fingerprint recognition device to the handle head, and the end of the lead hole is connected with the positioning hole.

[0009] Furthermore, the positioning hole is a square hole, and the groove is arranged on the hole wall of the square hole.

[0010] Furthermore, there are three grooves, which are arranged on three sides of the square hole, and no groove is arranged on the side where the lead hole and the positioning hole are connected.

[0011] Furthermore, a bearing is sleeved on the surface of the handle head, the inner wall of the bearing is tightly matched with the handle head, the outer wall of the bearing is tightly matched with the handle hole, and the end of the handle is against the plane of the inner ring of the bearing.

[0012] The utility model is beneficial in that:

[0013] 1. The handle is equipped with mounting holes and lead holes at the same time, which is compact and practical and effectively controls the overall size of the handle.

[0014] 2. During the installation process of the handle, the handle head can be quickly positioned through the positioning hole, making it easy to install.

[0015] 3. The mounting holes include threaded holes and positioning holes. A through hole is provided in the middle of the handle head. The bolt passes through the through hole and engages with the threaded hole to achieve the connection and fixation of the handle and the handle head. The axial positioning of the handle is achieved. In addition, the radial positioning of the handle can be further achieved by matching the three grooves of the positioning hole with the corresponding three bosses on the handle head. The combined effect of the two can prevent the handle from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
