Referring to FIGS. 2 and 7 , when the linking member 60 is driven by the inner rotating member 61 and moves toward the outer rotating member 63 along the length direction X to the second locking position, the pushing portion 612 that continues to rotate positively The second rail 614 will be separated from the linking member 60 . Since the convex portion 621 of the limiting member 62 is no longer pushed by the pushing portion 612 , the limiting member 62 will be subjected to the elastic force of the second elastic element 66 . It swings in the direction of the inner rotating member 61 and blocks the blocking surface 60c on the side of the blocking surface 60c facing the lock block 5 with the limiting portion 622 , so as to block the movement of the linking member 60 along the length direction X, and is stable in the Second lock position.

During the movement of the linking member 60 from the first locking position to the second locking position, the third slope 60g of the linking member 60 will guide the barb portion 641 of the unlocking member 64 to move away from the linking member 60 direction, when the link 60 is located at the second locking position and the barb 641 is separated from the third inclined surface 60g, the barb 641 will be subjected to the elastic force of the third elastic element 67 to move toward the The linking member 60 swings in the direction and is hooked on the third pushing surface 60f.

Thereby, the lock block 5 is still penetrated through the door frame 3, and the purpose of locking can also be achieved. The difference is that, as shown in FIG. 8 , when the user outside the door drives the outer rotating member 63 to rotate through the outer handle 72 or the user inside the door through the inner handle 74 , the first swing arm of the outer rotating member 63 rotates. 631 will synchronously drive the unlocking member 64 to move away from the inner rotating member 61, and when the barb 641 drives the linking member 60 to move to the unlocking position, the lock block 5 is separated from the door frame 3 to unlock the door. the goal of.

At this time, due to the blocking surface 60c and the third pushing surface on the linking member 60 60f moves away from the limiting portion 622 and the barb portion 641 respectively. Therefore, the link 60 can be moved to the unlocking position without being blocked, so that the lock block 5 can be separated from the door frame 3 to achieve purpose of unlocking.

Referring to FIGS. 7 and 4 , when the user outside the door operates the lock cylinder 73 through a key (not shown) to drive the inner rotating member 61 to rotate in the opposite direction, or the user inside the door operates the inner locking member 71 to drive the inner rotating member 61 to rotate in the opposite direction. When the inner rotating member 61 reversely rotates, the pushing portion 612 of the inner rotating member 61 will enter the second rail 614 and push the convex portion 621 of the limiting member 62 in the second The positioning member 62 swings away from the inner rotating member 61 , whereby the limiting portion 622 of the limiting member 62 is separated from the blocking surface 60c of the linking member 60 , and the linking member 60 is released, so that the linking member 60 Under the action of the elastic force of the first elastic element 65 , it moves away from the outer rotating member 63 along the length direction X, and returns to the first locking position.

It should be noted that this embodiment is not limited to being installed on the door leaf 2, and in other variations of this embodiment, as shown in FIG. Since those with ordinary knowledge in the art can infer the extended details according to the above description, no further description will be given.
