[0022] In this embodiment, the rotating shaft 3 cooperates with the limiting ring plate 7 and the limiting rail 6 for the rotation use of the movable carrier plate 4.

[0023] A number of groups of metal iron rods 8 are equidistantly distributed on the lower side of the movable carrier plate 4, and the metal iron rods 8 are attracted to the magnet plate 9.

[0024] In this embodiment, the position of the movable carrier plate 4 is fixed through the cooperation of the metal iron rods 8 and the magnet plate 9.

[0025] A cylinder 12 is clamped and installed on the fixed frame plate 11, and the telescopic rod 13 is fixedly connected to the output end of the cylinder 12.

[0026] In this embodiment, the lifting plate 14 is moved through the cooperation of the telescopic rod 13, the two groups of limiting rods 16 and the two groups of limiting hoops 17.

[0027] Specifically, first place several groups of plate-shaped aluminum die-castings into the interiors of several groups of transparent shell plates 5 respectively, and then start the air cylinder 12 on the lower side of the fixed support plate 11 to drive the telescopic rod 13 to contract.
