The invention relates to a marine variable-paddle-bending-degree propeller which aims at solving the problems that a traditional marine propeller is small in propulsive force, low in propulsive efficiency and not high in maneuverability and no technical schemes for improving the propulsive force and the propulsive efficiency of the propeller by changing the bending degree of the propeller exist. The marine variable-paddle-bending-degree propeller comprises a propeller hub and a plurality of paddles. Each paddle comprises a paddle body, a flap, a second flap driver, a flap fixing rod, a flap push rod and a displacement amplification mechanism. The paddles are evenly and fixedly arranged on the propeller hub in the circumferential direction. A flap installation hole is machined in each paddle body. The flap fixing rods are inserted in the flaps. The two ends of each flap fixing rod are fixedly arranged on the side walls of the corresponding flap installation hole. The displacement amplification mechanisms are arranged on the second flap drivers in a sleeving mode. Each second flap driver is fixedly arranged on the corresponding paddle body in the mode that the second flap driver is close to the corresponding flap installation hole. The marine variable-paddle-bending-degree propeller is used for the field of propeller manufacturing.
