The traditional hand-held small fan has a fixed shape and can only be used by hand. It is easy to hold it for a long time. The angle of the air outlet cannot be adjusted freely, and the blowing range is limited. It is difficult to liberate hands in desktop, camping, outdoor operations and other scenes. This product is aimed at multi-scene portable cooling requirements. On the basis of keeping the handheld fan compact and portable, it adds a universal snake bone hose that can be shaped arbitrarily, breaking the limitation of the traditional fan fixed form and taking into account the two use modes of handheld and bracket.
