Moreover, the push-pull mechanism generally adopts a gear linkage braking mode, but the phenomenon of abrasion or clamping and stopping easily occurs in the long-term use process of the gear, so that the service life is influenced.
For example, chinese patent 201610811290.7 provides a push-pull lock comprising a lock body and a push-pull mechanism disposed on the lock body, the push-pull mechanism comprising a housing, a first connector, a second connector, a third connector, a fourth connector, a gear assembly, a movable rod, a first rack, and a second rack; the shell comprises a first shell and a second shell, the second shell is covered on the first shell, a containing cavity is formed in the first shell, a first limiting hole, a second limiting hole, a third limiting hole and a fourth limiting hole are formed in the second shell, the first limiting hole, the second limiting hole, the third limiting hole and the fourth limiting hole are communicated with the containing cavity, and the shell is used for being fixed on the lock body; the first connecting piece is located in the first limiting hole at least partially, and the first connecting piece can slide in the first limiting hole. The push-pull lock can realize mutual switching of four unlocking modes of left push, left pull, right push and right pull, but the switching mode is complex. When the unlocking mode of left pushing is needed, the first connecting piece and the first rack are required to be dismounted, and the second connecting piece is required to be dismounted; when the unlocking mode of left pulling is needed, the first connecting piece and the first rack are needed to be dismounted, and the third connecting piece is needed to be dismounted; when the unlocking mode of right pushing is needed, the fourth connecting piece and the second rack are needed to be dismounted, and the second connecting piece is needed to be dismounted; when the unlocking mode of right pulling is needed, the fourth connecting piece and the second rack are required to be detached, and the third connecting piece is required to be detached. However, the first rack and the second rack are both located in the housing, and the housing is fixed in the lock body, so that when the unlocking mode is replaced, the lock body and the housing part need to be removed, then the gear assembly part is removed to detach the corresponding parts, and after the detachment is completed, the parts need to be installed back one by one again, so that the operation is complex, and the universality is poor. And the door is opened in a mode of joint control of the gear assembly, so that the gear is easy to rust or wear in the long-term use process, the phenomenon of blocking is caused, and the service life and the safety are influenced.
