Power output propeller

The invention relates to a booster of power output equipment such as an engine, an electric motor and the like, in particular to a power output propeller. The power output propeller comprises a power input wheel, a crankshaft, a plurality of connecting rocker arm, a one-way shaft, a power output wheel and a support, wherein the crankshaft and the one-way shaft are fixed on the support through bearings and are in a vertical position relation; a one-way bearing mounting hole is formed in the top of each connecting rocker arm, and the connecting rocker arms are mounted on the one-way shaft through one-way bearings; a chute track is arranged in the center of each connecting rocker arm and connected in series with one corresponding crank throw of the crankshaft, the crank throws are located in the chute tracks and can move along the chute tracks; the plurality of connecting rocker arms are mounted in parallel according to the structure so as to form the linkage whole. According to the power output propeller, output force of the power equipment such as the engine, the electric motor and the like are further converted and boosted, the power output capacity is increased, and low power input and high power output are realized.
