The invention relates to an electric hydraulic jack integrated main body being a cuboid metal block; an inner structure comprises a piston cavity, a one-way valve cavity, an oil hole and a motor shaft hole; the oil hole is an oil convey path in the metal block, connects the cavities or the cavities with the outer side of the integrated main body, thus forming an oil way body capable of conveying hydraulic oil and self-locking; the metal block enables the hydraulic oil to have good heat radiation effect; the motor shaft hole penetrates the integrated main body; the motor shaft hole and the oil hole connected with an oil pump are formed on the surface of the same side of the integrated main body, thus providing positions for directly mounting a motor and the oil pump, so the jack is compact in structure, and connecting oil leakage problems can be prevented; the electric hydraulic jack integrated main body is reasonable in structure; the formed electric jack is compact in structure, can effectively reduce oil leakage, and improves hydraulic oil heat radiation problem.
