The invention discloses a jack for adjusting an angle through a brake shoe. The jack comprises a turnover adjusting plate and a hydraulic cylinder, wherein the hydraulic cylinder is 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; a wedge is arranged between the fixed base and the turnover adjusting plate for adjusting the angle; and multiple steps corresponding to the bottom of the wedge are arranged on the fixed base. Through the mode, in the jack for adjusting the angle through the brake shoe disclosed by the invention, the included angle between the fixed base and the turnover adjusting plate is determined through the position of the wedge on the fixed base; the lifting angle of the hydraulic cylinder is adjusted through changing the position of the wedge; the support stability of the wedge to the turnover adjusting plate is good; the adjustment is convenient; and the whole structural strength is high.
