A dual rod positioning structure, for connecting and fixing two single rods sleeved on or inserted into one another, includes positioning holes respectively located on rod bodies of the two single rods and a positioning seat capable of being engagedly fixed to the positioning holes and sleeved on the single rods. The positioning holes are arranged on two adjacent sidewalls of the single rods. Inserted into the positioning seat are a positioning element selectively engaged in the positioning holes, a spring, a positioning pin and an outward protruding button. The positioning structure overall is structurally simple, convenient to assemble, and stable in terms of positioning.
