The abutment portion may have two symmetrically arranged or at least three circumferentially arranged portions, or may be annular.

The reversing process of the structure of the oblique lock tongue 2 of the door lock provided in the embodiment comprises the steps of moving the locking piece 3 in the direction away from the oblique lock tongue 2 through the opening 201, rotating the locking piece 3180 degrees after the locking piece 3 is moved to the first unlocking position, loosening the locking piece 3, and completing the reversing of the structure of the oblique lock tongue 2.

The unlocking process of the door lock provided in this embodiment includes providing a driving force for the driving component 500 by a mechanical key or a motor, driving the unlocking pulling piece 7 to rotate after driving the main bolt component to unlock for a period of time or in the unlocking process of the main bolt component, and driving the pushing piece 8 to move in a direction away from the inclined bolt 2 by the rotating unlocking pulling piece 7, and driving the locking piece 3 to move to a second unlocking position by the pushing piece 8, so that the inclined bolt 2 can retract into the lock case 200 to open the door by pushing the door body.

When unlocking is finished and the door handle or the mechanical key is released, the locking piece 3 is restored to the locking position under the action of the elastic force of the first elastic piece 6, and the inclined bolt 2 structure extends out of the lock case 200 under the action of the elastic force of the second elastic piece 300.

Although embodiments of the present invention have been described in connection with the accompanying drawings, various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the invention, and such modifications and variations fall within the scope of the invention as defined by the appended claims.
