The design is also based on the need to manually push the clutch fork 55 to move in the event that the motor 63 is de-energized and not functioning properly.

The cover plate 60 of the box body is provided with a relief hole 63, so that the shifting sleeve 40 can conveniently extend out of the clutch device to be connected with the shifting sleeve gear 52 and the square lock body rod.

Based on the design, the working principle of the fingerprint lock can be summarized as follows:

fingerprint verification is passed;

the operator presses the positioning member 212 so that the positioning member 212 is withdrawn from one of the positioning through holes 61;

after the handle 72 is turned to drive the turntable 30 to rotate by a specific angle, the positioning piece 212 is inserted into the other positioning through hole 61;

the motor 52 is energized to drive the clutch fork 55 to move in a direction approaching to the clutch pin 34, so that the clutch pin 34 is inserted into the limiting hole 41, and the reset block 30 can be connected with the dial sleeve 40;

the handle 72 is rotated, the turntable 30 is kept fixed, the handle 72 drives the reset block 30 to rotate so as to drive the shifting sleeve 40 to rotate, and simultaneously drives the square rod of the lock body fixedly connected with the shifting sleeve 40 to rotate, so that the fingerprint lock is unlocked.

Of course, the fingerprint authentication step may be performed after the handle 72 and the turntable 20 are rotated by a specific angle as a whole.

As can be seen from the above description, the fingerprint lock of the present invention is mainly characterized in that when the position of the handle 72 needs to be adjusted, only the positioning member 212 needs to be pressed and the handle 72 needs to be rotated, so that the working efficiency is greatly improved compared with the prior art that the screw needs to be unscrewed and then the handle needs to be rotated.

Preferably, the cover 50 of the case body is provided with a limiting groove 62, the limiting groove 62 is arc-shaped, and the limiting groove 62 is disposed around the relief hole 63. The reset block 30 is provided with a limiting portion 31, and the limiting portion 31 is provided with a limiting protrusion 312, wherein the limiting protrusion 312 is embedded in the limiting groove 62, so as to limit the rotation range of the turntable 20. Of course, if the operator wants to rotate the handle 72 360 degrees, the limiting groove 62 and the limiting protrusion 312 may not be provided.

Accordingly, the box cover 60 is provided with three positioning through holes 61, and the three positioning through holes 61 are equally spaced around the relief hole 63. Preferably, the angle between the connecting lines of the centers of the adjacent two positioning through holes 61 and the relief holes 63 is 90 degrees, in other words, when the positioning portion 212 is pulled away from one of the positioning through holes 61 and then inserted into the adjacent one of the positioning through holes 61, the turntable 20 is rotated by 90 degrees. Based on this, the position of the handle 72 with respect to the clutch device can be adjusted according to the operation habit of the operator. Assuming that the angle between the handle 72 and the clutch is 0 when the handle is aligned with the length direction of the clutch, the relative position of each positioning hole 61 and the positioning member 212 is adjusted by pressing the positioning member 212 and then rotating the turntable 30, and the angle by which the handle 72 can be rotated relative to the clutch is 90 degrees and 180 degrees. The operator can adjust the position of the handle 72 by selecting an angle suitable for his or her own operating habits. Of course, the number of the positioning holes 61 is not limited to three, and may be 2, or may be an integer greater than 3, which is specifically set depending on the operation habit of the operator.

Further, a turntable pad 24 is disposed between the turntable 20 and the communication hole 121, the communication part 12 includes a containing part 122 disposed around the communication hole, and a containing space is formed between the turntable pad 24 and the containing part 122 to place the fingerprint head wire 13. In addition, a second wire hole 123 is formed in the side plate of the case 10 far from the accommodating portion 11, and a third wire hole 714 is formed in the handle post 71, the third wire hole 714 is communicated with the accommodating portion 122, and the second wire hole 123 is communicated with the third wire hole 714, so that the fingerprint head wire 13 is conveniently extended out to be electrically connected with an external device. It can be seen that by providing the accommodating portion 122 for accommodating the fingerprint head wire 13, the fingerprint head wire 13 is prevented from coming into contact with other parts to interfere with the other parts.

Similarly, in the power module 50, the mounting box 51 includes a mounting cavity (not numbered), the motor 52 and the motor wire 521 connected to the motor 52 are disposed in the mounting cavity, and the mounting box 51 and the box body 10 are provided with corresponding first routing holes 112 so as to facilitate routing of the motor wire 521, which can prevent the motor wire 521 from contacting with other parts to interfere with the other parts.

In addition, the fingerprint lock of the invention can make the thickness of the clutch device smaller than or equal to 17mm through the above modularized design, thereby realizing the thin design of the fingerprint lock.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
