[0010] In one embodiment, the mounting surface of the extendable identifier is located in the first mounting cavity. After the extendable identifier is rotated, the curved surface is located in the first mounting cavity, and one end of the adjusting member abuts against the curved surface. After the other end of the adjusting member is moved, the abutting force between one end of the adjusting member and the curved surface is reduced, and the extendable identifier is rotated until the mounting surface is located in the first mounting cavity.

[0011] In one embodiment, the identifier housing has two opposite inner walls each having a first mounting hole, and the extendable identifier comprises a rotating shaft, an identifier mounting seat and a torsion spring; the two ends of the rotating shaft are movably mounted in the two first mounting holes respectively, the identifier mounting seat is sleeved on the rotating shaft, one side of the identifier mounting seat is the arc surface, and the other side is the mounting surface, the torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively connected to the identifier mounting seat and the inner wall of the identifier housing.

[0012] In one embodiment, two side panels are provided at the opening, and the end surfaces of the side panels are provided in an arc-shaped structure. When the mounting surface is located in the first mounting cavity, the arc-shaped surface and the end surfaces of the side panels are located in the same curved surface range.

[0016] In one embodiment, under normal conditions, there is a certain distance between the second limit plate and the identifier housing, and the adjustment rod is elastic. When the second limit plate is pressed, the adjustment rod moves toward the inside of the first installation cavity and drives the plug to move away from the limit groove.

[0019] The above-mentioned smart lock uses an extendable fingerprint identifier, and one of the arcuate surface and the mounting surface of the extendable identifier is always located in the first mounting cavity. When not in use, the mounting surface is located in the first mounting cavity, and the identifier body is mounted on the mounting surface, and the arcuate surface closes the opening. When it is needed, the extendable identifier is moved to allow the arcuate surface to enter the first mounting cavity. At this time, the mounting surface faces the outside of the identifier housing, and the user can perform fingerprint recognition. At the same time, one end of the adjustment member will abut against the arcuate surface and remain stable with the arcuate surface. After use, the adjustment member can be moved to eliminate the balance of the abutment force between the end of the adjustment member and the arcuate surface, so that the extendable identifier rotates back to its original position. This setting method can prevent the device from being exposed to the outside for a long time and contaminated with various dust or oil stains, which will affect the subsequent use effect, and also avoids the risk of collision with external objects.
