Abstract
The invention discloses a rotation adjusting structure of an electric fan. The rotation adjusting structure comprises a machine body, a connecting seat, a roll ball and a rotating shaft, wherein the roll ball is fixed on the machine body, and the connecting seat rotates around the rotating shaft relative to the machine body. The rotation adjusting structure also comprises a leaf spring which is fixed on the connecting seat, and the roll ball presses against the leaf spring and pre-presses the leaf spring. The connecting seat rotates to drive the roll ball to rotate, and because the elastic force of the leaf spring makes the roll ball able to elastically roll on the leaf spring, multi-angle elastic adjustment is realized. By the rotation adjusting structure of the electric fan, the connecting seat can perform multi-angle rotation relative to the machine body and is anti-abrasive, and the service life of the roll ball is prolonged.
