摘要： In pneumatic non-load quick dual-speed hydraulic jack, the small of piston ring (17) of hydraulic pump cylinder integrates with pump body (19) and external ring of step pump core (14) to form movable assembly. The middle part of step pump core (14) is provided with pump core step interface (8) used for conversion of hydraulic speed. The step hole on the same axis of pneumatic valve block on special pneumatic valve structure is provided with washer (48), button (49), pneumatic valve core (45), compressed spring (68) and valve core fastness set. The pneumatic valve parts can replace the hydraulic quick pump structure partially when the high-pressure air source is available. High-pressure air delivered to the oil reservoir of the external sleeve (4) presses the hydraulic oil into the oil chamber of oil cylinder, and thus facilitates the quick lift of jack piston under light load or empty load.

摘要： An adjustable hydraulic horizontal jack including a frame, a hydraulic unit, a jib unit, link rods, and a handle. Here, the structures of the jib and the link rod(s) are improved according to an embodiment. With the improved structures, the jack has rational structures and can act reliably. In addition, under the parameters equivalent to those of conventional hydraulic horizontal jacks, the jack of an embodiment of the present invention can change the height of the lowest position and the load by adjusting the length of the jib and link rods. Therefore, the jack is adapted to jacking up not only a light automobile with a low chassis but also a heavy automobile with a high chassis, thus having a wider scope of application.
