Secondly, four side struts 8 are rotatably connected to both sides of the side wall of the oxygen concentrator 1, and buffer plates 9 are elastically slidably connected to the ends of the side struts 8, and the side struts 8 are rotatably connected to the side walls of the oxygen concentrator 1 through damping shafts. When the oxygen concentrator 1 is carried and used, the side struts 8 and the buffer plates 9 can be used to auxiliary support the oxygen concentrator 1 from the side, so as to facilitate the convenient carrying and use of the oxygen concentrator 1;

[0025] In addition, when the oxygen concentrator 1 uses the side support rods 8 and the buffer plates 9 for auxiliary support from the side walls, for example, on a vehicle or in a transfer box, the side support rods 8 can be rotated to a suitable position through the damping shaft, and then the buffer plates 9 can slide out from the inside of the side support rods 8 elastically and support the side walls of the oxygen concentrator 1, thereby preventing the oxygen concentrator 1 from tipping over when being carried.
