The invention discloses a propeller folding and unfolding device for an unmanned aerial vehicle. The propeller folding and unfolding device comprises a bottom plate, three or more engine arms, a center ring, a driving component and a belt wheel 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, synchronous belt teeth are arranged on the center ring, a connecting rod is arranged between each engine arm and the center ring, and the driving component drives the center ring to rotate through the belt wheel transmission component and a synchronous belt so that the engine arms can be pushed to complete unfolding or folding through the connecting rods. The propeller folding and unfolding device has the advantages of being simpler in structure, easier and more convenient to operate, capable of greatly improving portability and the like.
