The invention relates to a foldable joint and a foldable frame. Each connecting pipe of the foldable joint can be coaxially hinged through the corresponding control connecting part, the corresponding first connecting part or the corresponding second connecting part, the hinge structure is simple, an external linkage structure is not needed, and the production efficiency can be effectively improved; during operation, a second rotating piece and a first rotating piece can be rotated in sequence to be folded or unfolded by controlling a control mechanism or even the control connecting part, and the operation process is simple and rapid; a second pin shaft can improve the rotating stability between a second rotating mechanism and the control mechanism; and meanwhile, the foldable joints are adopted, so that the front foot pipe, the rear foot pipe and the handle connecting pipe of the foldable frame can be quickly folded or unfolded, the structure is simple, potential safety hazards are small, and folding and unfolding of the foldable frame can be achieved through handle connecting rods.
