The revolvingly spraying tube 3 includes a transmitting tube 31 and a curved tube 32 connected with the transmitting tube 31. The transmitting tube 31 is inserted within the sheath tube 2. A front bearing 41 is provided in one end, near the curved tube 32, of the transmitting tube 31, and a rear bearing 42 is provided in the other end of the transmitting tube 31. The revolvingly spraying tube 3 has a front position limiting portion 33 radially protruding therefrom to retain the front side of the front bearing 41, and a rear position limiting portion 34 radially protruding therefrom to retain the rear side of the rear bearing 42. Thus, the revolvingly spraying device 100, 100a has fewer component parts and is convenient for assembly.</p> |
