The electronic lock locking structure prevents the plug from being detached from the socket. A motor is mounted inside the electronic lock, and the motor is rotated forward and backward by the forward and reverse voltages. 
The slot on the plug is locked during the forward movement to prevent the off-axis. The lock function releases the lock cylinder during reverse movement to achieve the unlock function. 
This type electronic lock is internally driven by a motor, 
• safe and reliable, 
• lower power  
• longer living life.
