A contact groove meshing with the outer wall of the gas cylinder 7 is opened at the top left side of the top block 8. The top block 8 plays a role in supporting and limiting the inclination angle of the gas cylinder 7.
[0027] Guide rails 9 are fixedly connected to both the front and rear sides of the left end of the fixing frame 4 where the gas cylinder 7 is located. Guide rods 10 are slidably connected inside the guide rails 9. The guide rails 9 are arranged in an arc shape. Sliders meshing with the inner walls of the guide rails 9 are arranged on the outer walls of the guide rods 10. The guide rods 10 extend outside the guide rails 9. A limiting ring A11 is fixedly connected between the guide rods 10 outside the gas cylinder 7. A limiting ring B12 is rotatably connected to the left side of the limiting ring A11. A notch meshing with the limiting ring A11 and the limiting ring B12 is opened at the left end of the top of the fixing frame 4. Moving rods 13 are rotatably connected to both the center position of the left side of the limiting ring A11 and the front and rear ends of the right side of the limiting ring A11.

A clamping port meshing with the welding assembly 25 is opened at the front end of the placing tray 24. When the welding is completed, the welding assembly 25 is wound on the placing tray 24, and the clamping port at the front end of the placing tray 24 limits the welding assembly 25.
[0031] Working principle: When the portable CO2 welding mobile cart is in use, the bottom of the gas cylinder 7 is inserted into the bottom support 6. At the same time, the limit ring B12 meshes with the limit ring A11. The limit ring A11 limits the gas cylinder 7 inside the limit ring B12 through the fastening rod 15 and the fixed ring 16. Rotate the moving rod 13, and the moving rod 13 drives the rubber pad 14 to perform centering limit on the gas cylinder 7. Push the top of the gas cylinder 7 to make it tilt, and the gas cylinder 7 rotates with the bottom support 6 as the axis. The gas cylinder 7 drives the guide rod 10 to move in the guide rail 9 through the limit ring A11. When the guide rod 10 moves to the right end of the guide rail 9, rotate the adjusting rod 20, and the adjusting rod 20 drives the limit block 19 to mesh with the guide rod 10. At this time, the gas cylinder 7 is completely limited. After welding is completed, wind the welding assembly 25 around the placement disk 24, and the clamping port at the front end of the placement disk 24 limits the welding assembly 25.
