The main tongue plate 15 is thus moved in the direction of the lock hole by the pressure of the spring assembly until it abuts against the main tongue lever, at which time the main tongue 2 is in the retracted unlocked state. At the same time, the latch bolt pulling plate 14 moves clockwise along with the square core rotating block 12, the latch bolt pulling rod 1401 moves downwards, and because the latch bolt pulling rod 1401 is abutted with the latch bolt assembly 4, the latch bolt assembly 4 moves downwards along with the latch bolt pulling rod 1401, at the moment, the latch bolt 404 is in a recovery unlocking state, the door can be opened, after the key is pulled out, at the moment, the latch bolt assembly 4 is popped up again due to the acting force of the latch bolt spring 405, the latch bolt pulling plate 14 can also return to the original position under the acting force of the latch bolt assembly 4, the square core rotating block 12 also returns to the position initially abutted with the latch bolt pulling plate 14 due to the abutting of the latch bolt pulling plate 14, and because the gear pulling plate 13 is separated from the square core rotating block 12, the position of the gear pulling plate 13 is not changed after the lock body is unlocked, at the moment, and the lock body is in an unlocking state.
