Abstract
The utility model discloses a ship propeller, which relates to the technical field of propellers, and comprises a mounting block, the outer wall of the mounting block is fixedly connected with a propeller blade, the outer wall of the mounting block is fixedly connected with a vortex elimination fin at the front end of the propeller blade, and the outer wall of the propeller blade is sleeved with a protective shell. The protective shell is composed of a first shell and a second shell, and the first shell and the second shell are connected through a connecting mechanism. By arranging the connecting mechanism, the connecting block is inserted into the connecting groove until the clamping block is clamped into the clamping groove under the action of the elastic force of the spring, and the connecting block is positioned; and after completion, a rotating block is rotated, the rotating block rotates to drive a threaded rod to rotate, the threaded rod rotates to drive an inserting block to move, the inserting block is inserted into an inserting groove to fix a clamping block, and the clamping block cannot move out of a clamping groove, so that the first shell and the second shell are fixedly connected, and the protective shell is conveniently and rapidly installed.
