[0037] As a further improvement of the present invention: a connecting hole 21 is provided on the inner wall plate of the side frame edge 2 at the lower portion of the lower cross beam 3, and a through groove 71 is provided on the inner wall plate of the movable support tube 7 along the height direction. The through groove 71 is located in the middle of the inner wall plate in the width direction, and the through groove 71 is connected to the inner cavity of the movable support tube 7;

[0038] The fastening and adjusting device 8 comprises a bolt 81, a nut 82 and an elastic self-fixing member 83, and the elastic self-fixing member 83 is made of plastic material;

[0039] The nut 82 is mounted on the elastic self-fixing member 83 , which is mounted in the movable support tube 7 . The bolt 81 passes through the connecting hole 21 and the through-groove 71 and is screwed into the nut 82 .

[0040] Bolt 81 is a round-head hexagonal countersunk bolt. To adjust the height, loosen bolt 81, then move the movable support tube 7 inward, retracting it into the side frame 2, or extending it a certain distance outward. The elastic self-fixing device 83, nut 82, and bolt 81 remain stationary, while the movable support tube 7 moves relative to the elastic self-fixing device 83. After adjusting the height, tighten bolt 81 again, making adjustment easy.
