[0010] Furthermore, the first auxiliary component includes a first sleeve, a tensioning shaft that passes through the first sleeve along the z direction, and a tensioning assembly connected to the tensioning shaft. The side surface of the first sleeve is provided with a plurality of first openings along the x direction. One end of the tensioning shaft is fixedly connected to the first sleeve, and the other end is movably connected to the tensioning assembly. The first openings are located on one side of the lamp pole, two in total, and are symmetrically arranged. The tensioning shafts are also arranged corresponding to the number of the first openings, and the tensioning shafts are arranged adjacent to the first openings, or directly pass through the first openings, so that the closing movement of the first openings can be faster, thereby connecting the lamp pole better and faster.
