Patent attributes
A rotating assembly is provided and is adapted to be assembled on a foot stand. The rotating assembly includes a limit ring, a base, a spherical friction part, and a pressing module. The limit ring is adapted to be fixed on the foot stand. The base is movably assembled on the limit ring along an axis. The base and the limit ring form a space. The spherical friction part is rotatably disposed in the space between the limit ring and the base. The pressing module is adapted to be fixed on the foot stand. The pressing module is configured on one side of the base along the axis, and pushes the base to a direction of the limit ring to compress the space formed by the base and the limit ring, so that the spherical friction part is in contact with the limit ring and the base. The spherical friction part is temporarily maintained at a specific angle by friction between the spherical friction part and the limit ring and friction between the spherical friction part and the base. A universal ball joint assembly is further provided.
