Its principle is based on the pressure difference across, let it be the transformation of energy. If the pressure of the liquid with the machine mechanical energy transfer to each other the two can be transformed into each other. The design of this thesis is the use of a hydraulic jack hydraulic transmission principle. But also the use of typical products of hydraulic transmission. Hydraulic jacks with small, which has no complicated structure, installation firm, low weight, easy to carry, easy handling, easy maintenance, transmit force, a single person can be done, and many other advantages, so that we can in many Construction saw his shadow. In particular, widely used in automotive repair and family car tire change during unloading ideal as the main tool. In practice, we often encounter production manual alone is very difficult, such as transfer of goods, alignment, clamping and other processes, we need the help of hydraulic jacks. Also home car to change a tire, for example, and car repair workshop and other places, need to use the jack to help us. Our lives are often nece
