The invention discloses an efficient hydraulic jack which comprises a base, a pressure relief assembly, a driving mechanism, an oil pump assembly, a bevel disc, a first shell, a second shell, an oil cylinder, a piston rod and an annular sliding rail, a plurality of oil pumps are used for pumping oil to the piston rod in turn, and compared with a single oil pump pumping mode, the interval time between oil suction and output of the oil pumps can be greatly shortened; therefore, the working efficiency is improved; the jack works by pulling the handle, and compared with a traditional operation rod moving mode, the jack can be used by an operator more conveniently; and the handle is quickly pulled in the no-load state, so that the oil pumps quickly pump oil to enable the piston rod to extend outwards, and the working preparation time is saved.

    本发明公开了一种高效液压千斤顶,包括底座、泄压组件、驱动机构、油泵组件、斜面圆盘、第一外壳、第二外壳、油缸、活塞杆和环形滑轨,通过多个油泵轮流泵送油液至活塞杆,相较于单个油泵泵送的方式,能够大幅减少油泵吸油与输出的间隔时间,从而提高工作效率;通过拉动手柄的方式使千斤顶工作,相比传统移动操作杆的方式,能够更为方便操作者使用;在空载状态下快速拉动手柄,使多个油泵快速泵送油液让活塞杆向外伸出,从而节省了工作准备时间。
