Abstract
A self-assembly micro fan includes a body, a plurality of blades and flexible joints, with any one of the blades being connected to the body by one of the flexible joints while each flexible joint is regarded as a pivot to move the blade connected therewith to have an angle relative to a radial direction of the body. Besides, each of the flexible joints has plural link members or at least one link member and extension member to provide variable types of shape of the micro fans, so that the air driving efficiency of the self-assembly micro fan is improved.
