The invention discloses a jack with adjustable base angle. The jack comprises a first fixed seat, a hydraulic cylinder and a hydraulic pump. The hydraulic cylinder and the hydraulic pump are vertically arranged on the first fixed seat. A second fixed seat is arranged below the first fixed seat, a pin shaft is arranged between the lower portion of one end of the first fixed seat and the upper portion of one end of the second fixed seat for hinge joint, a baffle is arranged on the other end of the second fixed seat, a wedge block is arranged on the inner side of the baffle, and the slope on the upper portion of the wedge block is located below the first fixed seat. In this way, by means of the jack with the adjustable base angle, the displacement of the wedge block is changed through an adjusting bolt, the larger the distance, going deep into the position below the first fixed seat, of the wedge block is, the larger the inclination angle of the first fixed seat is, the telescopic pointing angle of the hydraulic cylinder is changed accordingly so that the jack can adapt to hoisting work of various angles, stability is good, adjustment is convenient, and the application range is wide.
