[0023] The servo motor 4 is started to drive the rotating rod 5 to rotate, and the rotating rod 5 drives the rectangular rod 10 and the round rod 22 to rotate. An oscillation structure consisting of a circular ring 9, a rectangular rod 10, a rectangular groove 20, a round rod 22 and a wave groove 21 is installed on the annular surface of the rotating rod 5.
