Abstract
A rotatable ball joint is provided. The rotatable ball joint is adapted to enable an object to be rotatably assembled on a foot stand, where the foot stand includes a fixed hole. The rotatable ball joint includes a friction part, a shapeshifting sphere, and an assembly part. The shapeshifting sphere is adapted to be compressed from a first state to a second state. A size of the shapeshifting sphere in the first state is greater than a size of the fixed hole, and a size of the shapeshifting sphere in the second state is less than the size of the fixed hole. The shapeshifting sphere is adapted to be disposed in the fixed hole. The shapeshifting sphere is connected to the assembly part. The object is adapted to be assembled on the assembly part. The friction part is configured on an outer surface of the shapeshifting sphere. When the shapeshifting sphere is disposed in the fixed hole, the friction part is in contact with an inner wall surface of the fixed hole to temporarily maintain the rotatable ball joint at a specific angle relative to the foot stand. A universal ball joint assembly is further provided.
