The working principle of this invention is: When the user uses the key to open the door from outside, the key is inserted into the hole and then rotates. It drives the lock rod to rotate. The lock rod pushes the lifting pin into the through hole. Afterwards, the user only has to continue to rotate the handle or key in the same direction, the door will be unlocked. Afterwards, please rotate back the key to enable the lifting pin to spring back through the lifting pin spring. The outer rotary shell and the inner rotary shell no longer have the engaged movement relationship, then, if the outer rotary shell is revolved, it is in the idling condition.

When the outdoor unlocking motor is started, the communication equipment or intelligent panel sends signal to the control core to drive the motor. Then, the shaped cammed wheel rotates and prizes the connecting rod, and moves forward the push shell above the connecting rod. As the push rod moves, it drives the transmission mechanism in the push shell to advance forward as well. The lifting pin will be inserted into the inserting hole of the ratchet wheel.
