After the fingerprint panel 2 transmits information to the circuit board 28 and the fingerprint matching is successful, the battery 26 will transmit electricity to the motor 5 to drive the device to operate, and the lock can be opened.

[0033] It should be noted that the present utility model is a fingerprint lock for a jewelry box. When a user needs to open the jewelry box, the finger is placed on the fingerprint panel 2 on the front side wall of the box wall 1. The fingerprint panel 2 identifies the user's fingerprint. If the fingerprint matching is successful, an unlocking signal is sent to the circuit board 28 inside the lock box 3.

[0034] After receiving the unlocking signal, the circuit board 28 is connected to the motor 5 through a line, and the motor 5 starts. The output terminal of the motor 5 drives the first bevel gear 6 to rotate. Since the first bevel gear 6 meshes with the second bevel gear 8, the rotation of the first bevel gear 6 causes the second bevel gear 8 to start rotating outside the first connecting rod 7. The first cylindrical gear 9 behind the second bevel gear 8 also rotates synchronously.

[0035] The rotation of the first cylindrical gear 9 drives the meshing second cylindrical gear 12 to rotate. The second cylindrical gear 12 is rotationally connected to the second connecting rod 10 through a fixing ring 11. The first rack 13 on the right side of the fixing ring 11 moves as the second cylindrical gear 12 rotates.

[0036] The movement of the first rack 13 drives the meshing second rack 17 to move. The second rack 17 is fixed to the left side wall of the support rod 15. The support rod 15 is rotationally supported by a support rod 14. As the second rack 17 moves, the support rod 15 starts to rotate around the support rod 14. During this process, the first spring 16 in the middle hole groove on the front side wall of the support rod 15 plays a role in buffering and assisting in resetting.

[0037] When the first rack 13 is rotating, the three gears on the right side of the first rack 13 will mesh with the second rack 17 to drive the second rack 17 and the support rod 15 to rotate upward. At the same time, the latch 18 on the right side of the support rod 15 will move downward and out of the inside of the buckle 19. When the second rack 17 rotates upward, it will drive the second rack 17 to rebound and reset through the first spring 16 inside the support rod 15, so that it meshes with the first rack 13 on the fixed ring 11 when unlocking next time.

[0038] The right side wall of the support rod 15 is fixedly connected with the latch 18. As the support rod 15 rotates, the latch 18 gradually moves away from the buckle 19 in the inner hole of the front plate 4. The right end of the buckle 19 is fixedly connected with the connecting plate 20. When the latch 18 leaves the buckle 19, under the action of the second spring 25, the connecting plate 20 moves to the right. The left outer side of the linkage rod 23 is slidably connected inside the fixed block 22, and the right outer side is fixedly connected with the connecting ring 24. The left side wall of the connecting ring 24 is fixedly connected with the right end of the second spring 25. Under the pulling force of the second spring 25, the connecting plate 20 drives the buckle 19 to move to the right, thus realizing the unlocking of the jewelry box.

[0039] When it is necessary to lock the jewelry box, the system sends a locking signal, and the motor 5 rotates in the reverse direction. Each component starts to move in the reverse direction, and the latch 18 moves closer and combines with the buckle 19 again to realize the locking of the jewelry box.
