Those skilled in the art can understand that the material tray 3 is directly placed on the two first optical axes 4, and the material tray 3 rotates with the traction of the consumable material feeding work, and the two first optical axes 4 can reduce the resistance of the material tray 3 to rotate. In addition, the support body 1 can adapt to material trays 3 of different sizes, which can improve the utilization rate of the support body 1.

[0024] Furthermore, the first side frame includes a first oblique beam 12, a first top cross beam 11, a second oblique beam 16, a first ring body 13 and multiple groups of reinforcing ribs 14; the first oblique beam 12, the first top cross beam 11, the second oblique beam 16 and one side of the bottom frame form a trapezoidal outer frame; the first ring body 13 is located in the trapezoidal outer frame; one end of the multiple groups of reinforcing ribs 14 are connected to the outer wall of the first ring body 13, and the other end radiates outward and is connected to the trapezoidal outer frame; the second side frame has the same structure as the first side frame.
