Abstract: A rotation connection mechanism includes a plate assembly, a movement structure assembly, and a torsion structure assembly. The plate assembly includes a middle plate, a first plate, and a second plate. The first plate is rotatably connected to the middle plate. The second plate is rotatably connected to the middle plate. The movement structure assembly includes a first movement structure and a second movement structure. The first movement structure is arranged at a first end of the plate assembly. The second movement structure is arranged symmetrically with the first movement structure and arranged at a second end of the plate assembly. The torsion structure assembly is arranged on a side of the middle plate and includes a first torsion structure and a second torsion structure. The first torsion structure cooperates with the first movement structure. The second torsion structure cooperates with the second movement structure.
