Abstract
A rotation joint structure includes a fixed joint, a movable joint, a first limit member, and a second limit member. The fixed base has a locking groove. The movable joint is pivotally connected with the fixed joint. The movable joint has a first slideway and a second slideway connected to each other. The first limit member is movably mounted in the first slideway. The second limit member is movably mounted in the second slideway. When the second limit member is locked in the locking groove, and the first limit member stops the second limit member, the movable joint is locked and cannot be rotated. Thus, the movable joint is disposed at a two-stage locking state.
