The circumferential surface of the disk is a spherical surface which is matched in the spherical cavity of the rotating block, so that the disk can freely rotate in the spherical cavity in 360 degrees in all directions.

In addition, the thickness of the disc should be less than the width of the elongated slot. Thus, the disc can be put into the spherical cavity from the elongated notch; when the circumferential surface of the disk is attached to the spherical cavity, the disk can be rotated, and the disk can be positioned in the spherical cavity and cannot be separated outwards through the elongated notch. Of course, the diameter of the circular through hole should be larger than the diameter of the inclined support rod to avoid interference with the circular through hole when the inclined support rod rotates. When the inclined supporting rod is rotated downwards to be in a roughly horizontal position, the inclined supporting rod rotates from the circular through hole to be positioned in the positioning opening, and at the moment, the first panel and the second panel can be unfolded in the folding through hole in an unfolding mode, so that the folding panel is in an unfolding state. It should be noted that the inclined support bars are arranged transversely and close to the width side of the front side of the folding through hole.
