The invention provides a lifting jack, and belongs to the technical field of automobiles. The problem that an existing lifting jack cannot be repeatedly used after being triggered is solved. The lifting jack comprises a barrel-shaped shell, a driving shaft capable of sliding in the axial direction of the shell is arranged in the shell in a penetrating mode, the outer end of the driving shaft extends out of the shell, a limiting piece capable of being connected with the driving shaft and axially limiting the driving shaft is arranged in the shell, a driving spring connected with the driving shaft and an unlocking structure capable of relieving axial limiting of the driving shaft are further arranged in the shell, and after the limiting piece relieves limiting, the driving spring can drive the outer end of the driving shaft to move in the direction away from the shell. The lifting jack has the advantage of being capable of being repeatedly used after being triggered.
本发明提供了一种举升器,属于汽车技术领域。它解决了现有举升器在触发后无法重复使用的问题。本举升器包括呈筒状的壳体,壳体内穿设有能沿壳体轴向滑移且外端伸出壳体的驱动轴,壳体内设置有能与驱动轴相连并将驱动轴轴向限位的限位件,壳体内还设置有与驱动轴相连的驱动弹簧和能解除驱动轴轴向限位的解锁结构,当限位件解除限位后驱动弹簧能带动驱动轴外端朝远离壳体方向运动。本举升器具有在触发后能重复使用的优点。
