In this patent, the folding connection structure is composed of a first fixed plate, a second fixed plate and a connecting plate. The first fixed plate is arranged at both ends of the side of the first plate, the second fixed plate is arranged at both ends of the side of the second plate, and the connecting plate is arranged in the middle position of the outer side of the first fixed plate and the second fixed plate, and the ends of the connecting plates are provided with bearings. The first fixed plate and the second fixed plate are both movably connected to the connecting plate through bearings, and the first plate and the second plate are movably connected through a folding connection structure. It has a foldable movable connection structure, which reduces the assembly process during use and improves the convenience of use.

[0004] When using the above patent, we found that the device does not have the ability to rotate and position the bearing, which causes the plate to rotate easily when unfolding or folding, thereby affecting the stability of the plate during use.
