The inserting conductive connection device of a lamp rod includes a pair of upper lamp rod and a lower lamp rod, an inner walls of the upper lamp rod and lower lamp rod are formed with a first threaded section and a second threaded section, respectively; a connecting seat assembled to a top of the lower lamp rod. The connecting seat includes a large annular surface and a small annular surface; a conductive seat assembled to a bottom of the upper lamp rod. In assembly, an annular cork and a positioning ring are locked to an interior of the upper lamp rod and lower lamp rod, respectively, for positioning the lamp rod. Since the positioning ring is not directly locked to the upper lamp rod; when the positioning ring is locked by hand tool, the insertion of the receptacle and plug will not be affected.
