The invention provides a propeller quick-release mechanism. The propeller quick-release mechanism comprises a motor and a propeller which are mounted at the tail end of an aerofoil, wherein the lower part of the propeller is movably connected with a propeller mounting base; arc-shaped clamping grooves with opposite openings are formed in the propeller mounting base; the rotating end of the motor is movably connected with a cuboid-shaped motor mounting base; a retractably connected pressing shaft is arranged on each of the two sides of the motor mounting base; a pin shaft is fixed in the horizontal direction perpendicular to each pressing shaft; a groove adapting to the pressing shafts is formed in the arc-shaped part of each clamping groove; the arc-shaped parts and the pin shafts are in movable limited connection with each other. Through retraction of the pressing shafts, the propeller can be mounted and dismounted, the limit structure is reasonable, the flight demand is met, quick replacement and collection of vulnerable parts are realized conveniently and quickly, and particularly, when the propeller quick-release mechanism is used for mass production and use, low efficiency caused by the reason that professionals and professional tools are not in place is avoided.
