That is, as shown in fig. 3 and 4, the compression spring 34 is disposed along the length direction of the reset cavity 3301, and since the stopper 321 is located at the opening 3302 of the reset cavity 3301, one end of the compression spring 34 disposed in the reset cavity 3301 may be connected to the stopper 321; since the other end of the reset cavity 3301 is not opened, the other end of the compression spring 34 can abut against the inner wall of the other end of the reset cavity 3301. This corresponds to the both ends of the compression spring 34 acting on the stopper 321 and the unlocking body 33 of the second housing 32, respectively. When unlocking, the unlocking body 33 is forced to extend out of the first accommodating chamber 301 through the opening 3011, and the compression spring 34 is compressed. In the reset operation, the unlocking main body 33 is returned to the first accommodating chamber 301 by the elastic force of the compression spring 34.

The handle 40 is connected to one side of the lock case 10 and has a square shaft. The handle 40 is operable by a user to open the door.

The clutch 50 is disposed in the lock case 10. The clutch 50 has a spindle 51, and the unlocking mechanism 30 is located beside the clutch 50. When unlocking, for example, the circuit main board 20 is triggered by means of fingerprint identification, card swiping sensing or password input, so that the circuit main board 20 sends an unlocking instruction to the unlocking mechanism 30, and the unlocking main body 33 of the unlocking mechanism 30 pushes the mandrel 51 of the clutch 50 under the control of the circuit main board 20; specifically, the circuit main board 20 triggers the motor 333 of the unlocking main body 33, so that the motor 333 drives the second interlocking member 337 to move, the second interlocking member 337 pulls the first interlocking member 334 through the tension spring 336, the first interlocking member 334 pushes the latch bolt 335 to extend out of the opening 3304 of the second accommodating cavity 3303, and the latch bolt 335 pushes the spindle 51 of the clutch 50 to move, so that the spindle 51 is pushed to eject and then drives the square shaft of the handle 40 to rotate, thereby opening the door. After the electronic lock is opened and after a certain time interval, the latch 335 is returned to the second receiving cavity 3303 by the elastic force of the tension spring 336, that is, the tension spring 336 pulls the latch 335 back to the second receiving cavity 3303 by pulling the first linking member 334.

Further, the electronic lock further comprises a fingerprint identification module 60, and the circuit main board 20 is electrically connected with the fingerprint identification module 60, so that the unlocking mechanism 30 controlled by the circuit main board 20 is unlocked in a fingerprint identification mode.

The electronic lock further comprises a card swiping sensing module 70, wherein the card swiping sensing module 70 is electrically connected with the circuit main board 20, so that the circuit main board 20 controls the unlocking mechanism 30 to unlock the lock in a card swiping mode.

The electronic lock further includes a password input module (not shown in the figure), and the password input module is electrically connected to the circuit main board 20, so that the circuit main board 20 controls the unlocking mechanism 30 to unlock the lock by inputting a password.

The electronic lock further comprises a display screen 80, and the display screen 80 is connected with the circuit main board 20.

It can be understood that, by providing the fingerprint identification module 60, the card swiping sensing module 70 and the password input module, and the fingerprint identification module 60, the card swiping sensing module 70 and the password input module are all electrically connected to the circuit main board 20, the electronic lock can be opened by any one of fingerprint identification, card swiping sensing and password input. In all of the three unlocking modes, the motor 333 in the unlocking main body 33 is controlled by the circuit main board 20 to realize automatic unlocking.

When the user uses the key to unlock the lock, the entire unlocking body 33 is pushed out of the first accommodating chamber 301 by the insertion of the key, and the pressing spring 34 is compressed. The unlocking body 33 is then retracted again into the first receiving chamber 301 by the action of the compression spring 34, and the reset is effected. Thus, after unlocking, the unlocking body 33 can always return to the original state. Further, the unlocking main body 33 can be maintained in the initial state by the elastic action of the pressing spring 34, and the unlocking main body 33 is not easily moved from the initial position even if external force is applied, thereby preventing a lawbreaker from unlocking with another tool. For example, it is possible to prevent a lawbreaker from attracting and operating the unlocking body 33 to move out of the first cavity 301 on the outer surface of the lock case 10 by a strong magnet to unlock the lock.

It is to be understood by persons skilled in the art that the embodiments of the present invention described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished.
