The invention discloses an inclined angle-adjustable jack. The jack comprises a turnover adjusting plate, a hydraulic pump and a hydraulic cylinder, wherein the hydraulic pump and the hydraulic cylinder are vertically arranged on the turnover adjusting plate; a fixed base is arranged below the turnover adjusting plate; the fixed base and one end of the turnover adjusting plate are hinged by a pin shaft therebetween; two waist holes are formed in the other end of the turnover adjusting plate; the fixed base is provided with two swing rods respectively extending above the waist holes; and fastening bolts extending into the waist holes are arranged at the outer side of the fixed base. Through the mode, in the inclined angle-adjustable jack disclosed by the invention, the heights of the swing rods extending above the turnover adjusting plate are changed by using the fit between the fastening bolts and the swing rods; the included angle between the fixed base and the turnover adjusting plate is adjusted; the extension pointing direction of the hydraulic cylinder is changed; and the proper lifting angle is adjusted, so that the angle adjusting flexibility is good, and the lifting stability is high.
