[0023] The conveying platform 101 is shaped like a rectangular plate. A fixed frame 102 is arranged directly above the conveying platform 101, and the fixed frame 102 is composed of two groups of vertical plates spaced below and n-shaped plates arranged horizontally directly above the vertical plates.
