The present invention illustrates an electric fan includes a motor, a rotatable disc and a fan blade. The motor has a driving shaft extended outwardly, the rotatable disc is connected with an end of the motor, and a fan shaft is pivotally connected on the rotatable disc and obliquely disposed relative to the driving shaft. The fan blade is disposed on the fan shaft. A connecting member is disposed between the driving shaft and the fan shaft. The rotatable disc is driven by a driving device to drive the fan shaft to rotate about the driving shaft, so as to expand a blowing range of airflow generated by the fan blade.
