The invention discloses a pitch angle fine adjustment mechanism of an aerial variable pitch propeller, the propeller and a method. The pitch angle fine adjustment mechanism comprises an adjustment worm and an adjustment turbine. The adjusting worm comprises an operation section and a worm section which are connected in sequence; the adjusting turbine comprises a front shaft section, a turbine section and a rear shaft section which are connected in sequence; the worm section is meshed with the turbine section; the two adjusting worms are distributed on the two sides of the adjusting turbine in parallel. An eccentric connecting hole is axially formed in the adjusting turbine and used for being connected with an eccentric variable-pitch pin. Fine adjustment of the pitch angle of the propeller can be achieved, pitch angle errors of different blades are eliminated, and the consistency of the pitch angles among the multiple blades is improved.
