Abstract
A rotating means for a suction tube is capable of adjusting the position of the suction valve. Such means is mainly made of a suction valve. The interior of the suction valve is in communication with each other. The rear end of the suction valve has a first connecting tube. Further, a second connecting tube is provided at the front end of the suction valve opposing the first connecting tube. The interior of the second connecting tube is connected to a rotating tube. The outer periphery of the rotating tube is provided with a resilient protruding ring, so that a gap is formed between the rotating tube and the inner periphery of the second connecting tube. Finally, the second connecting tube is connected to a sleeve, and the sleeve is then connected to the outer periphery of the rotating tube. With the gap formed between the rotating tube and the second connecting tube, the rotating tube and the second connecting tube can be displaced with respect to each other, thereby to adjust and rotate the position of the suction tube.
