According to the locking assembly, a stopping part is movably connected to a pre-tightening fixing base, and the stopping part is fixedly connected to the head end of a driving unit so as to have limiting force. The locking component is connected to the pre-tightening fixing base relative to the stopping component, the locking component has rotating force, and when the locking component is in the limiting state, the locking component is connected with the stopping component in a clamped mode and is limited under the effect of limiting force of the stopping component. After the head end of the driving unit moves, the stopping part is separated from the head end of the driving unit, the limiting force of the stopping part is relieved, the locking part is driven by the rotating force to rotate to the clamping tooth part of the locking shaft head, locking of the locking shaft head is achieved, and therefore the problem that in the locking process in the prior art, the risk of locking switching sinking is prevented is solved.
本申请公开了一种锁止组件,止挡部件活动连接于预紧固定底座,且止挡部件固定连接于驱动单元的首端,以具有限定力。锁止部件相对止挡部件连接于预紧固定底座,锁止部件具有转动力,并在限定状态时,锁止部件与止挡部件卡接,并在止挡部件的限定力的作用下被限定。在驱动单元的首端移动后,止挡部件与驱动单元的首端分离,止挡部件的限定力解除,锁止部件在转动力的带动下转动至锁止轴头的卡齿部,以实现对锁止轴头的锁止,从而解决现有技术中在锁止过程中,防止锁止切换下沉的风险的问题。
