The invention discloses a variable-pitch transmission mechanism of an unmanned aerial vehicle rotor wing and a corresponding variable-pitch mechanism, and belongs to the technical field of unmanned aerial vehicles. A transmission mechanism of an unmanned aerial vehicle rotor wing comprises a variable pitch supporting rod, a fork-shaped piece and an adjusting mechanism. One end of the variable-pitch strut is connected with a steering engine of the unmanned aerial vehicle, and the other end is rotationally connected with the fork-shaped piece; an adjusting mechanism is hinged to the fork-shaped piece and comprises a variable-pitch pull rod and a variable-pitch ring, and a fixing clamp is arranged on the variable-pitch ring. A pitch changing mechanism of an unmanned aerial vehicle rotor wing comprises a rotor wing, a propeller hub and a transmission mechanism. The propeller hub comprises a shaft hole and a supporting arm, the variable-pitch supporting rod penetrates through the shaft hole, the variable-pitch ring is sleeved outside the supporting arm, and the fixing clamp is located between double-layer structures of the supporting arm. A propeller root part of the rotor wing is of a flat structure and is arranged on a fixing clamp of the variable-pitch ring; and the paddle root is connected with the support arm through a spherical hinge bearing. The transmission mechanism is simple in structural design, high in transmission flexibility, good in stability, capable of increasing the lift force of the unmanned aerial vehicle during flight and increasing the maximum flight speed and suitable for small unmanned aerial vehicles.
