Here, the end of the touching slider 30 that is engaged with the rotating piece 20 may be elastically deformed, and when the portion of the touching slider 30 that extends out of the lock base 10 reaches a set value, the end of the touching slot 32 that is engaged with the touching slot 31 is elastically deformed, so that the engagement between the two ends is broken.

In order to allow the contact slide 30 to automatically protrude outside the lock base 10, a contact slide drive 33 for driving the contact slide 30 to protrude outside the lock base 10 is preferably also provided in the lock base 10. Further preferably, the touching slider driving mechanism 33 is a compression spring, one end of which is in contact with the inner wall of the lock base 10, and the other end of which is in contact with the touching slider 30. Of course, the above-mentioned touch slider driving mechanism 33 may also be two permanent magnets, one of which is disposed on the lock base 10 and the other of which is disposed on the touch slider 30.

In order to make the touching slide 30 better contact with the door frame and at the same time be able to be separated from the groove on the door slot, the end of the touching slide 30 extending out of the lock base 10 is preferably provided with a ball 300. Of course, the end of the touching sliding block 30 extending out of the lock base 10 may be a roller, or the end of the touching sliding block 30 extending out of the lock base 10 may be a hemispherical shape.

Referring to fig. 2, 3 and 4, in order to facilitate the user to unlock the lock of the present invention by using a key, a main tongue poking plate 40 is further rotatably disposed inside the lock base 10, a main tongue guiding sliding block 41 is disposed on the main tongue poking plate 40, and a main tongue guiding sliding groove 42 matched with the main tongue guiding sliding block 41 is disposed on the main lock plate 110; meanwhile, a key poking piece 50 is rotatably arranged on the lock base 10, and meshing teeth which are mutually matched and driven are arranged between the key poking piece 50 and the main tongue poking piece 40; when the main tongue pulling piece 40 rotates, the main tongue guiding sliding block 41 slides along the main tongue guiding sliding groove 42 to drive the main lock plate 110 to drive the main tongue 11 to extend out of the lock base 10 or retract back into the lock base 10. Therefore, when the lock of the present invention is used in cooperation with a lock core, the pins on the lock core are inserted into the pin holes 500 formed in the key blade 50, and when the user rotates the lock core with a key, the pins on the lock core drive the key blade 50 to rotate, and the key blade 50 drives the main tongue blade 40 through the engaging teeth to drive the main lock plate 110 and the main tongue 11 to retract into the lock base 10, thereby realizing the function of unlocking with a key.

In addition, in order to realize door opening by adopting a door handle, a handle pulling piece 60 is preferably further rotatably arranged in the lock base 10, and meshing teeth which are mutually matched and driven are arranged between the handle pulling piece 60 and the main tongue pulling piece 40.
