With the arrangement, only the adjusting section 51 is exposed outside, and the rest parts of the conductive wires 50 are located inside the transverse frame 22 and the vertical frame 21, so that the conductive wires can be effectively protected. And the adjusting section 51 is arranged at the connecting part of the transverse frame 22 and the vertical frame 21, so that the adjusting section 51 is far away from the suspension lamp head 40, and the risk that the adjusting section 51 is touched by a user by mistake is reduced.
