Abstract

The invention provides a cascade fan structure that is easy to assemble, has a strong bonding force and can effectively alleviate mutual interference. The cascade fan comprises a fan frame, a plurality of movable blade portions which are connected in cascade along an axial direction of the cascade fan, a first retainer mounted inside the fan frame for receiving and retaining a first movable blade portion, and a second retainer detachably coupled to the first retainer for receiving and retaining a second movable blade portion.
