[0032] Specifically, through two groups of positioning grooves 16 and positioning rods 15, the rotating wind tube assembly 3 can be assembled on the top of the chassis 2 for positioning to prevent the angle from being deviated. The semicircular button 18 can be rotated to be stuck in the bottom of the sink groove 13, thereby fixing the rotating wind tube assembly 3. The second bolt 19 is rotated to enter the second threaded hole 17 to fix the rotation angle of the semicircular button 18 and prevent the semicircular button 18 from rotating.
