The invention relates to the technical field of propellers, and discloses a lift-type adjustable-pitch full-revolving propeller for a ship. The propeller comprises a base fixed on a hull; a lifting assembly, wherein the fixed end of the lifting assembly is fixed on the base; a propeller body which is arranged at the movable end of the lifting assembly and comprises a propelling shaft, a propeller and a screw pitch adjusting piece, wherein the screw pitch adjusting piece is arranged on the propelling shaft and can move in the axial direction of the propelling shaft so as to adjust the screw pitch of the propeller; a rotating assembly which is arranged at the movable end of the lifting assembly and comprises a rotating power piece and a rotating shaft, wherein the rotating power piece can drive the propelling shaft and the propeller to rotate through the rotating shaft; and a rotating assembly which is arranged at the movable end of the lifting assembly and comprises a rotating power piece and a rotating shaft, wherein the rotating power piece can drive the propeller body to rotate through the rotating shaft. The lifting type pitch-adjustable full-revolving propeller disclosed by the invention solves the problems of high noise and high resistance to a ship in the prior art, and can be suitable for various occasions.
