The improved unmanned aerial vehicle variable pitch mechanism comprises a fuselage, four sets of racks are arranged on the outer side of the fuselage, driving assemblies are installed at the other ends of the racks, lifting assemblies are arranged at the lower ends of the driving assemblies and comprise lifting motors, the lifting motors are arranged at the lower ends of the racks, and threaded hollow rotating rods are arranged in the lifting motors; a lifting rod is installed at the upper end of the threaded rod through a bearing and penetrates through a driving assembly, the driving assembly comprises a driving motor, the driving motor is installed at the upper end of the rack, rotors are movably installed on the two sides of the upper end of the driving motor, and distance adjusting supports are fixed to the inner sides of the rotors; the upper end of the lifting rod is connected with the distance adjusting support through a distance changing control rod. Through the collaborative design of rigid constraint of the screw transmission threaded rod, the limiting strip groove and the limiting block, the transverse transmission path of a traditional steering engine is simplified into longitudinal coaxial linear driving, and the mechanical gap and inertia delay are remarkably reduced.
