[0019] The fixing mechanism 9 is installed on the outer wall of the column 1. The fixing mechanism 9 includes a flexible fixing ring 901, a protective sleeve 902, a fixing rod 903, a mounting bracket 904, a sliding sleeve 905, a mounting hole 906, and a locking rod 907. The flexible fixing ring 901 is sleeved on the outer wall of the column 1. The inner wall of the flexible fixing ring 901 is provided with a protective sleeve 902. A fixing rod 903 is installed at one end of the outer wall of the flexible fixing ring 901, and a mounting bracket 904 is welded to the other end of the outer wall of the flexible fixing ring 901. A sliding sleeve 905 is welded to the outer wall of the mounting bracket 904.
