The invention discloses a propeller folding device for an unmanned aerial vehicle. The propeller folding device comprises a bottom plate, three or more engine arms, a center ring, a driving component and a gear transmission component. The engine arms are sequentially arranged on the bottom plate in the circumferential direction, one end of each engine arm is hinged to the bottom plate through a shaft and can rotate around the hinge point, and the other ends of the engine arms are used for allowing a propeller component of the unmanned aerial vehicle to be mounted. The center ring is located in the middle of the bottom plate, the gear transmission component is mounted on the peripheral side of the center ring, transmission teeth for being matched with the gear transmission component are arranged on the center ring, a connecting rod is arranged between each engine arm and the center ring, and the driving component enables the center ring to rotate through the gear transmission component so that the engine arms can be pushed by the connecting rods to rotate to complete unfolding or folding. The propeller folding device has the advantages of being simpler in structure, easier and more convenient to operate, capable of greatly improving portability and the like.
