The structure can reliably drive the limiting lock to move through the handle driving mechanism, so that the limiting lock can move stably and reliably. Specifically, the inner handle driving piece can directly drive the main lock tongue and the oblique bolt to unlock when the door is in the door, the oblique bolt can only be unlocked when the door is out of the door, and the outer handle driving piece can be used for opening the door when the main lock is retracted into the lock body and the door is in a half-open state. The outer handle can unlock the latch bolt, when the main lock extends out of the lock body, the outer handle can not open the door, when the main lock retracts into the lock body (namely, in a half-open state), the outer handle can open the door, and the temporary door closing effect is achieved.
