Box fan

The utility model relates to an electric fan technical field discloses a box fan, including down casing and stabilizer blade, lower casing is equipped with mount table that extends from its internal surface and the through -hole that pierces through the external surface of inferior valve from the mount table up end, the stabilizer blade includes the base, rotation axis that follow base upper surface extends and the block portion that sets up from two at least intervals that the rotation axis extends, block portion keeps away from rotation axis one end surface and is equipped with and has relative with the base supporting and lean on supporting of face and lean on the part, the rotation axis is rotatably inserted and is located the through -hole, support and wear out the mount table up end by the part, the base upper surface is held with inferior valve external surface counterbalance, support and hold by face and the counterbalance of mount table up end, in order will descend the casing card at the base and between supporting by the face, make casing and base axial position relatively fixed down, thereby the stability when improving the box fan operation, the rotation axis is the adjustable base of rotation in the casing through -hole and the relative position of casing down under, but according to actual need adjusts the stabilizer blade position at any time.
