Description

technical field

[0001] The invention relates to a quick installation mechanism for a propeller of a multi-rotor aircraft, which is mainly used for quick installation of the propeller for a multi-rotor aircraft. Background technique

[0002] A multi-rotor aircraft refers to a special flight device with three or more rotor shafts, which is equipped with a motor on each shaft to drive the propeller (rotor) through transmission to generate lift. The propellers used in traditional multi-rotor aircraft are generally fixed and locked to the output shaft end of the motor. In order to improve the convenience of use, most of the existing propellers for multi-rotor aircraft adopt a quick installation mechanism, which is detachably connected to the output shaft end of the corresponding motor.

[0003] Existing propeller rapid installation mechanisms for multi-rotor aircraft generally include a fixed base fixed to the output shaft end of the motor and a connector detachably mounted on t...
