Abstract: A movable type frame assembly includes upright rods, connecting seats, support rods, and frame bodies. End portions of the connecting seats are provided with insert slots along X, Y, and Z-axes. Each connecting seat is further provided with a vertical insert hole corresponding to a position between two adjacent insert slots. One insert slot of the connecting seat receives a top end of the upright rod. The horizontally insert slots receive support rods such that they make a frame structure. The frame body is placed on the frame structure, and has comer end portions provided with indentations for butting against the connecting seats. Each indentation is provided with a hook for engaging the insert hole of the connecting seat. The vertical insert slots of the connecting seat may receive an additional upright rod or support rod of the same diameter to permit formation of a multiple-tier frame assembly.
