The invention discloses a hydraulic jack which comprises a jack body and a sleeve movably installed on the jack body. The sleeve is provided with an open end and a closed end, a multi-stage telescopic rod is installed at the open end of the sleeve, and the multi-stage telescopic rod can be retracted into the sleeve; and a locking piece for locking the multi-stage telescopic rod in the sleeve is arranged at the closed end of the sleeve. The hydraulic jack is novel in design and easy to operate, and due to the arrangement of the multi-stage telescopic rod, the multi-stage telescopic rod is shrunk in the sleeve and is not prone to being lost; the multi-stage telescopic rod is drawn out of the sleeve and can be used as a rotating wrench to work; through the arrangement of the locking piece, when the jack body is not used, the locking piece can lock the multi-stage telescopic rod in the sleeve, and carrying and using are convenient; and through arrangement of a stop block and a through hole, the locking effect of the locking piece on the multi-stage telescopic rod in the sleeve can be further enhanced.

    本发明提出了一种液压千斤顶,包括千斤顶主体以及活动安装在千斤顶主体上的套筒,其中:套筒具有开口端和封闭端,套筒开口端安装有多级伸缩杆,多级伸缩杆可收缩进行套筒内;套筒封闭端上设有用于将多级伸缩杆锁定在套筒内的锁件。本发明设计新颖,操作简单,通过多级伸缩杆的设置,多级伸缩杆收缩在套筒内,不易丢失;多级伸缩杆从套筒抽出,可充当转动扳手进行工作;通过锁件的设置,千斤顶主体不使用时,锁件可以将多级伸缩杆锁定在套筒内,携带方便,使用方便;通过挡块与通孔的设置,可以进一步的增强锁件对多级伸缩杆在套筒内的锁定效果。
