The invention discloses a portable double-loop insulating supporting rod for pole replacement. The portable double-loop insulating supporting rod comprises at least two sets of supporting cylinders which are mounted together in a sleeved mode. When conducting wires need to be supported, the first lower supporting cylinder and the second lower supporting cylinder can be separated to be in a horizontal state and positioned through a positioning device; then according to the actual need, the first middle supporting cylinder and the second middle supporting cylinder are separated by a certain angle, and the first upper supporting cylinder and the second upper supporting cylinder are separated by a certain angle; then positioning between the first lower supporting cylinder and the first middlesupporting cylinder, between the first middle supporting cylinder and the first upper supporting cylinder, between the second lower supporting cylinder and the second middle supporting cylinder as well as between the second middle supporting cylinder and the second upper supporting cylinder is achieved through connecting rods; and then the conducting wires are hung on hooks, thus the conducting wires can be fixed, and the phenomenon that wire phase spacing is too small is avoided.
