At present, the known locking mechanism generally requires the user to input the correct electrical signal through an external device when in use, so that the control circuit in the box provides power to the locking mechanism to realize electronic opening; after use, the safe is closed, and the electric drive locking mechanism is used to restore the security locking state of the safe. However, the existing locking mechanisms of this type are generally designed to be relatively simple, not safe enough, and cannot effectively avoid the use of external force to push the lock tongue to forcibly release the security locking state during use. The security performance is poor, and when the electric drive of the locking mechanism fails, it is difficult to open the safe. The locking mechanism can only be violently disassembled to open the safe, which is very inconvenient to use.
