The invention discloses an unmanned aerial vehicle wing driving mechanism. The unmanned aerial vehicle wing driving mechanism comprises a driving motor fixed in a vehicle body, the output end of the driving motor is provided with a first rotating rod, the first rotating rod is connected with a third rotating rod through a length-adjustable second rotating rod, and the end of the third rotating rodis provided with a lantern ring used for being connected with a rotating shaft; and threads are arranged at the two ends of the second rotating rod, the rotating directions of the threads located atthe two ends of the second rotating rod are opposite, threaded sleeves are connected to the two ends of the second rotating rod in a threaded mode, one threaded sleeve is rotationally connected with the first rotating rod, and the other threaded sleeve is rotationally connected with the third rotating rod. One thread sleeve is rotationally connected with the first rotating rod through a first bearing, and the other thread sleeve is rotationally connected with the third rotating rod through a second bearing; and the middle part of the second rotating rod bulges outwards to form a polygonal prism. The unmanned aerial vehicle has the advantages that the driving motor is not easy to damage, flight accidents are not easy to cause, the wind resistance is small, the maintenance is easy, the application range is wide, and the service life is long.
