The invention discloses a lifting angle-adjustable jack. The lifting angle-adjustable jack comprises a first fixed plate, a hydraulic pump and a hydraulic extension cylinder, wherein the hydraulic pump and the hydraulic extension cylinder are respectively arranged on the first fixed plate in a perpendicular manner; a second fixed plate is arranged below the first fixed plate; one ends of the first fixed plate and the second fixed plate are hinged by a pin shaft; two thread sleeves are arranged on the first fixed plate; and thread rods downwards pointed to the second fixed plate are respectively arranged in the thread sleeves. Through the mode, in the lifting angle-adjustable jack disclosed by the invention, a handle rotates to change the lengths of the thread rods below the first fixed plate, so that an included angle between the first fixed plate and the second fixed plate can be changed, the pointing direction of the hydraulic extension cylinder is adjusted, and the adjusting convenience is good; and the bottom of the second fixed plate is on the ground, so that the support stability is good, and the operation is safer.
