Therefore, the arrangement form can enable the motor to drive the rotating shaft to do rotary motion, further drive the compression or expansion motion of the rotary spring, and the rotary spring is fixed in the lock tongue cavity, so that the rotary spring can drive the lock tongue to move up and down along the shaft of the rotating shaft.
