Background

The jack is light and small lifting equipment which takes a rigid jacking piece as a working device and jacks a heavy object through a top bracket or a bottom supporting claw within a small stroke. The jack is mainly used for the departments of factories, mines, transportation and the like as vehicle repair, other lifting, supporting and the like. The structure is light, firm, flexible and reliable, and can be carried and operated by one person. The jacks are divided into a mechanical jack, a hydraulic jack and the like, and the principles are different. In principle, the most basic principle on which a hydraulic drive is based is pascal's law, i.e. the pressure is uniform throughout the liquid. Thus, in a balanced system, a relatively small piston exerts a relatively small pressure thereon, while a large piston exerts a relatively large pressure thereon, which can keep the liquid stationary. Therefore, different pressures at different ends can be obtained by the liquid transfer, and the purpose of conversion can be achieved. The common hydraulic jack uses the principle to achieve the force transmission. The screw jack pulls the handle in a reciprocating way, the claw pushes the ratchet wheel to rotate in a clearance way, the bevel pinion drives the bevel pinion to rotate the lifting screw rod, and therefore the lifting sleeve can be lifted or descended to achieve the function of lifting tension, but the screw jack is not as simple as a hydraulic jack.
