ことが出来る。 A second embodiment of the present invention is shown in FIGS. 2-4. In this embodiment, as shown in FIG. 2, the ring 21 has a pair of vertical holes 21A and a pair of horizontal holes 21B.
The vertical hole 21A is located at the top and the horizontal hole 21B is located at the bottom. A large number of rings 21 are arranged vertically and horizontally, and rods 22 are passed through vertically and horizontally through vertical holes 21A and horizontal holes 21B, and nuts 23 are screwed onto both ends of the rods 22. The rings 21 are interconnected and fixed to the tray 20.
Configure. In this embodiment, the size of the tray can be adjusted by increasing or decreasing the number of rings 21 arranged.
