when the door is locked, the lock core gear rotates the main gear, and the two convex blocks on the main gear stir the main tongue poking plate to deflect by taking the rotating support shaft as the center to push the square tongue plate on the square tongue assembly to extend out of the door; when the door is opened, the master gear is driven by the lock cylinder gear to rotate reversely, the main tongue poking plate deflects reversely by taking the rotating support shaft as a center, and the main tongue poking plate pushes the square tongue plate on the square tongue assembly to retract;
when the spatula is retracted to the tail end, the main gear is meshed with the upper shifting fork, and the upper shifting fork drives the middle shifting fork to rotate and retract the spatula assembly; when the lock core gear stops rotating to an idle state, the upper shifting fork, the middle shifting fork, the main gear and the latch bolt on the latch bolt assembly automatically reset under the action of the latch bolt spring on the latch bolt assembly.
2. The lock body with the handle capable of opening the door left and right according to claim 1, wherein a mechanical lock cylinder liner for driving the lock cylinder gear to rotate is further installed on the lock body shell.
3. A lock body having a handle for opening doors from left to right according to claim 1, wherein a driving motor for driving the gear of the lock cylinder to rotate is further installed in the lock body housing.
4. The lock body of claim 1, further comprising an upper hook and a lower hook, wherein the upper hook and the lower hook are respectively disposed on the upper hook and the lower hook, and the upper hook and the lower hook are respectively engaged with a pushing block disposed on the tongue plate, and the upper fork drives the main tongue plate to deflect, and the upper hook and the lower hook are driven to extend together to realize a back-lift door lock.
