Abstract: An improved connection structure for the supporting rod of a floor lamp, which can easily be disassembled for packing, and assembled quickly to use; the top part of the rod has a rotary switch and a joint member; the upper part of the stub connector is provided with two recess points, and a L-shaped groove. A joint member is provided with two L-shaped connecting grooves and a slanting-and-curved side so as to facilitate the joint member to connect with the upper end of the stub connector. The joint member also has a round hole for receiving wire terminals; when the supporting rod is disassembled, the wires of the lamp can also be disassembled for packing convenience; therefore, the structure of the supporting rod can provide high safety for the wires.
