The invention discloses a guide-tube type double-flow-direction propeller. The propeller comprises a propeller hub, inner propeller blades, a water tube, propeller blades and a guide tube, the inner propeller blades are located between the propeller hub and the water tube, the 2-4 inner propeller blades are evenly distributed on the propeller hub, the propeller blades are located between the water tube and the guide tube, the 2-4 propeller blades are evenly distributed on the water tube in a side-inclined mode, the guide tube is located outside the propeller blades, and the gap between the inner wall of the guide tube and the propeller tip of each propeller blade ranges from one millimeter to three millimeters. By means of the mode, a guide tube double-flow-direction structure is adopted for the propeller, and the propelling efficiency of the propeller can be effectively raised.
