The adjusting blocks are movably arranged at the bottom of the base; the adjusting cavity is formed in the base; the three-way piece is arranged in the main body and used for connecting the hydraulic cavity, the oil inlet pipe and the adjusting cavity; the pressure plate is movably arranged in the adjusting cavity; the gradienter is arranged on the base and used for detecting the levelness of the base and the ground; wherein a guide groove is formed in the top in the adjusting cavity and concaves inwards in the direction of the hydraulic cavity, and the pressure plate is partially embedded into the guide groove so that the pressure plate can slide in the extending direction of the guide groove. Hydraulic oil is contained in the adjusting cavity, and the multiple adjusting blocks are driven to move by moving the pressure plate. The base is further provided with a limiting assembly used for limiting the pressure plate. The jack has the beneficial effect that the jack which can automatically adapt to irregular terrains and is stable and safe is provided.
