Two circular ring supports are symmetrically mounted on the front end and the rear end of the pedestal. Circular ring rotating frames are rotatably mounted in the circular ring supports. Rolling balls are hermetically mounted between the circular ring supports and the circular ring rotating frames. Two groups of arc racks are mounted on the inner circumferences of the circular ring rotating frames longitudinally symmetrically. The teeth of the arc racks are disposed on the outer surface of the arc racks. An upper moving mechanism and a lower moving mechanism are mounted on the two groups of arc racks symmetrically with the circle center of the arc racks. Rotating teeth are disposed on the circumference of the circular ring rotating frame extended from the circular ring supports. A driving gear is meshed with the rotating teeth.
