As shown in fig. 1 and 2, the barrier strips 2 are uniformly fixed on the cylindrical surface of the inner side of the outer cylinder 3 along the circumference, and the jet flow ejected by the jet hole 10 is directed to the barrier strips 2, so that the reverse acting force of the jet flow on the rotating cylinder 4 is enhanced, and the rotating speed of the rotating cylinder 4 is improved.
