The invention discloses a thin type hydraulic lifting jack. The thin type hydraulic lifting jack comprises a hydraulic cylinder body and a piston top rod cylinder arranged inside the hydraulic cylinder body, wherein a first groove is formed in the lower part of the piston top rod cylinder; a first sealing ring is arranged inside the first groove; a second groove is formed in the top of the inner wall of the hydraulic cylinder body; a second sealing ring is arranged inside the second groove; an oil inlet is formed in one side of the lower side wall of the hydraulic cylinder body; an oil outlet is formed in the other side of the lower side wall of the hydraulic cylinder body; a ring-shaped oblique oil inlet notch is formed in the bottom of the piston top rod cylinder, so that the bottom of the piston top rod cylinder is trapezoidal. The thin type hydraulic lifting jack is simple and reasonable in structure, good in sealing performance and relatively high in start-up speed.
