when the electronic lock is in a locked state and needs to be unlocked, a user presses the awakening mechanism 12 to enable the electronic lock to enter a normal working state, then the user scans the two-dimensional code through terminal equipment or confirms the identity through modes such as fingerprint identification and the like, and after the identity is confirmed, the circuit board sends an instruction to the motor 6 to enable the motor 6 to rotate, and the lock tongue 5 is synchronously driven to move towards the lock tongue spring 4 to enable the lock tongue spring 4 to be compressed. When one side of the cam main body 72 is contacted with the sensing end of the first travel switch 8, the motor 6 stops, and at the moment, the lock tongue 5 is separated from the locking groove 21, so that the lock hook 2 moves upwards under the stretching force of the lock hook spring 3 to realize unlocking, meanwhile, the contact of the lock tongue 5 and the sensing end of the second travel switch 9 is sensed by the second travel switch 9, the electronic lock is confirmed to be in an unlocking state, and the result is sent to the terminal equipment through the circuit board; after the lock hook 2 moves upwards to realize unlocking, the motor 6 is synchronously reset to enable the cam 7 to be separated from the first travel switch 8, but the lock tongue 5 cannot be reset because the lock tongue 5 is tightly pressed by the lock hook 2. The electronic lock is unlocked through the steps.

When this electronic lock is for unblock state and need shutting, the user aligns the second lockhole with the short hook arm of latch hook 2 to promote the short hook arm of latch hook 2 downwards to in the second lockhole, make magnet 15 sensed by the magnetic inductor. Meanwhile, the long hook arm of the lock hook 2 synchronously moves downwards to enable the lock hook spring 3 to be compressed until the locking groove 21 is aligned with the lock tongue 5, then the lock tongue 5 is clamped into the locking groove 21 due to the stretching force of the lock tongue spring 4 to realize locking, the lock tongue 5 is synchronously separated from the second travel switch 9, the electronic lock is confirmed to be in a locking state, and the result is sent to the terminal equipment through the circuit board. The electronic lock is locked through the steps. However, if the latch hook 2 is damaged, the magnet 15 is forced to leave the sensing range of the magnetic sensor, and the circuit board sends a warning signal to the control end for warning.

The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
