The blocking rod 51 is fixed to the inner side wall of the mounting hole and is parallel to the axis of the mounting hole. A second spring 56 is provided between the sliding plate 50 and the bottom of the mounting hole. A plurality of limit blocks 46 are fixed at equal intervals in the circumferential direction on the side of the sliding plate 50 away from the second spring 56.

The vertical plate 53 and the rotating block 47 are coaxially arranged, and a damping plate 52 is arranged between the vertical plate 53 and the rotating block 47.

[0047] During use, the button 44 is pressed, which drives the shaped member 45 to move, separating the sliding plate 50 from the limiting plate 49 and allowing the limiting block 46 to escape from the limiting hole 54. The first rod 21 is then rotated to adjust the angle of the first rod 21. The button 44 is then released, and the sliding plate 50, under the action of the second spring 56, approaches the limiting plate 49, allowing the limiting block 46 to penetrate into the limiting hole 54, thereby fixing the first rod 21 at the desired angle. The second rod 22 operates in exactly the same manner as the first rod 21.

[0050] The gas pipe 23 is passed through several limiting rings 24, and the limiting rings 24 are fixed to the outer walls of the second rod body 22 and the first rod body 21. The several limiting rings 24 are coaxially arranged and evenly spaced along the length direction of the second rod body 22 and the first rod body 21, so that the second rod body 22 and the first rod body 21 drive the position of the gas pipe 23 to change through the limiting rings 24; several auxiliary rollers 32 are rotatably connected to the inner wall of the limiting ring 24, making it easier for the staff to pull the gas pipe 23 and facilitate adjusting the length of the gas pipe 23.
