A revolvingly spraying device includes a sheath tube and a revolvingly spraying tube. The revolvingly spraying tube includes a transmitting tube and a curved tube connected with the transmitting tube. The transmitting tube is inserted within the sheath tube. A front bearing is provided in one end, near the curved tube, of the transmitting tube, and a rear bearing is provided in the other end of the transmitting tube. The revolvingly spraying tube has a front position limiting portion radially protruding therefrom to retain the front side of the front bearing, and a rear position limiting portion radially protruding therefrom to retain the rear side of the rear bearing. Thus, the revolvingly spraying device has fewer component parts and is convenient for assembly. |
