step three: after the moving mechanism (5) is lifted, the stabilizing plate (33) rotates to drive the moving plate (51) to rotate, so that the moving plate (51) drives the ejector rod (71) to extrude the rotating block (76) to turn over when moving, and the ejector rod (71) slides over the top of the rotating block (76); when ejector pin (71) reset, the arc surface of ejector pin (71) lateral wall can contact with the arc surface of rotatory piece (76) lateral wall earlier, rotatory piece (76) lateral wall is injectd by anti-rotating plate (79), at this moment, ejector pin (71) can be pushed ejector pin (71) and drive baffle (75) extrusion second spring (74) shrink, ejector pin (71) can enter into the inside of overhead tank (72), the top of rotatory piece (76) is slided to the tip of ejector pin (71), when the instant of ejector pin (71) slip rotatory piece (76) top, second spring (74) can jack up baffle (75) downwards, baffle (75) drive ejector pin (71) joint once more to the one side of rotatory piece (76).
