Background

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 on it, while a large piston exerts a relatively large pressure on it, which keeps the liquid still. 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 pulls 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 lift or descend to achieve the function of lifting tension.

The existing hydraulic jacks are generally used in diameter or combined with corresponding outer framework mechanisms, but the angles of the existing hydraulic jacks cannot be adjusted, and the angle adjusting mechanism is relatively flexible, so that the bearing range is limited, and the existing hydraulic jacks are easy to collapse; the jack is of an integral structure or a relatively stable structure and serves as an auxiliary mechanism, so that the bearing degree is increased, and collapse is prevented.
