[0006] In one embodiment of the present invention, the angle between the connecting arm and the inner wall of the frame is 35 degrees to 60 degrees.

[0007] In one embodiment of the present invention, the angle between the connecting arm and the inner wall of the frame is 45 degrees.

[0008] In one embodiment of the present invention, the abutting portion has a fitting inclined surface that fits with the connecting arm.

[0009] In one embodiment of the present invention, the fixing portion is perpendicular to the inner wall of the frame, which facilitates the use of the bending section of the stamping die.

[0010] In one embodiment of the present invention, the bottom plate or the frame is made of metal.

[0011] In one embodiment of the present invention, the connecting arm and the fixing portion are formed by stamping.

[0012] In one embodiment of the present invention, the bottom plate is provided with a positioning hole.

[0013] The present invention also provides a fingerprint lock, comprising any one of the above-mentioned connection structures of the frame and the bottom plate.

[0014] In one embodiment of the present invention, it further comprises a silicone pad provided with a connecting column, the edge of the silicone pad has a flange for covering the connecting port, and the connecting column corresponds to the position of the positioning hole.

[0015] In the invention, there is no need to set up additional hardware. The connection between the frame and the bottom plate can be completed by placing the abutting part into the connecting port and bending the bending section. The material consumption is small and the connection is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
