An oscillating fan, by adding an oscillating motor, to drive the drive gear to move along the periphery of the fixed gear, the oscillating motion of the fan is achieved is disclosed. The fan motor is only used for driving the blades to blow air in a rotating mode, so that the load of the fan motor is reduced, and the oscillating motion stability of the blades driven by the drive gear is ensured. Meanwhile, the installation space of the oscillating and rotating pivot part is reduced, so that the whole oscillating fan is small in size, convenient to transport.
