Therefore, the door body can be conveniently opened or closed in daily life by arranging the inclined tongue, and the door body does not need to be opened by a key every time the door is opened or closed. When the door is opened, the square tongue is driven to retract into the lock body by the rotation of the key, the inclined tongue is driven to retract by further rotation of the key, the door body is opened, and the inclined tongue extends out of the lock body after the key is pulled out. The inclined tongue is provided with an inclined plane so as to force the inclined tongue to automatically retract into the lock body after the inclined plane collides with the door frame when the door body is closed, and the inclined tongue automatically extends into the lock hole after the inclined tongue is aligned with the lock hole on the door frame. In order to ensure stable locking and matching, the shape of the lock hole corresponds to that of the inclined tongue.
When the lock body is installed on the daily door body, due to the type of the door frame or the installation position of the door frame, the positions of the lock holes of the corresponding oblique tongues on the door frame are different, such as the inner side faces of the lock holes of the corresponding oblique tongues deflect towards the inner side of the door or the inner side faces of the lock holes of the corresponding oblique tongues deflect towards the outer side of the door, thus, the installed oblique tongues are not matched with the lock holes, the oblique tongues cannot be inserted into the lock holes after the door body is closed, the door frame can only be installed again or the orientation positions of the oblique tongues on the lock body can only be adjusted, the orientation of the oblique tongues is fixed, the reversing cannot be carried out, and the door frame is fixed on the wall surface, so that the detached integrity cannot be ensured.
