Abstract
A fan device is provided, including a fan assembly. The fan assembly includes fan blades, locking sliders, adjusting components, and elastic components. A peripheral side wall of the rotating module defines movable cavities, and each of the locking sliders is slidable and disposed in a corresponding one of the movable cavities. Each of the elastic components is disposed in a corresponding one of the movable cavities, and two ends of each of the elastic components are respectively abut against a top surface of the corresponding one of the movable cavities and a corresponding one of the locking sliders. In a normal state, each of elastic components drive the corresponding one of locking sliders to move toward a bottom surface of the corresponding one of the movable cavities.
