Safe electronic lock of general lock cylinder

The invention provides a safe electronic lock of a general lock cylinder, and relates to the field of electronic locks. The safe electronic lock comprises a key and the lock cylinder. A communicationend, a drive motor, an inner lock cylinder and an outer lock cylinder are arranged in the lock cylinder. Starting of the drive motor needs to obtain passing of encryption verification of the communication end. The drive motor pushes a lifting valve located in the inner lock cylinder, and therefore a fixed clamp retreats into the lifting valve. The output end of a shaft of the lifting motor is connected with a lifting valve control end in the outer lock cylinder. The lifting valve control end is located in a groove below a connecting buckle. The inner lock cylinder and the outer lock cylinder are rotated at the same time so as to rotate an unlocking driving lever, and the aim of unlocking is achieved. According to the safe electronic lock, unified general specifications are adopted, low-cost fast upgrading and replacement can be achieved, and the requirement of domestic and civil use is met; the drive motor can be started only by obtaining passing of encryption verification of serial and wireless Bluetooth at the same time, the inner lock cylinder and the outer lock cylinder are rotated at the same time through the drive motor so as to rotate the unlocking driving lever, and the aimof unlocking is achieved; and the safe electronic lock is safer.
