A shaking frequency adjustable electric fan is composed of a supporting body (1), the fan head (2), the fan head under the regulating member (3), (4), a large piece of assembly of motor current breaking and the size of the adjusting knob (5), small motor current breaking and adjusting knob (6). The fixed gear (7), a limiting piece (8), polarity conversion parts (9), large motor (10), small motor (11), (12), bolt nut (13), polarity conversion and small motor fixed on the plate assembly. It mainly solves the existing electric fan amplitude and frequency can not be adjusted according to the needs of the users of the lack of the design of the frequency adjustable adjustable head limiting piece can adjust the fan range through the electric fan, small motor by adjusting the current size can adjust the fan frequency, the head frequency and amplitude adjustable function of electric fan and bring some convenience for users living, this design suitable for occasions to promote the use of a fan in a variety of needs.
