The jack comprises a telescopic component and a loading component, the telescopic component is provided with a limiting plate, an outer pipe and an inner pipe, the inner pipe is located in the outer pipe and movably connected with the outer pipe along the center line of the outer pipe, the outer pipe is of a hexagonal pipe structure, and the loading component is arranged on the outer pipe. The limiting plate is fixedly installed outside the outer pipe and is only connected with one side face, the extending direction of the limiting plate on the outer pipe is parallel to the center line of the outer pipe, a limiting hole is formed in the limiting plate, and the loading component is movably installed on the outer pipe. The jack capable of rapidly adjusting the height is provided with a flexible detachable structure, and the operation height adjusting process combining rough adjustment and fine adjustment is formed. The position change of the operation height of the load-carrying component is large and time-consuming during coarse adjustment, the change of the length of the telescopic component, namely the change of the overall operation height of the jack is small and time-consuming during fine adjustment, the effect of quickly adjusting the operation height is finally achieved, and time and labor are saved.

    本发明公开了一种高度快速可调式千斤顶,它包括伸缩部件和载重部件,所述伸缩部件设有限位板、外管和内管,所述内管位于外管内部并且内管沿着外管的中心线与外管活动连接,所述外管为六角管结构,所述限位板固定安装在外管的外部且只与其中一个侧面连接,所述限位板在外管上的延伸方向平行于外管的中心线,所述限位板上设有限位孔,所述载重部件活动安装在外管上。高度快速可调式千斤顶具有灵活的可拆装结构,形成粗调与微调相结合的作业高度调节过程;粗调时载重部件的作业高度位置变化大、用时少,微调时伸缩部件的长度变化即千斤顶整体的作业高度变化小、用时少,最终获得作业高度的快速调节效果,既省时、又省力。
