Fixed on the horizontal line, when the wrench 23 is lifted upwards, the end of the wrench 23 near the connecting piece is recessed into the through hole of the connecting piece, the fixing piece 25 is loosened, and the welder can fold the end connected to the second folding piece 11 inwards by 90° for storage.

Adjust the spacing according to the diameter of the flange's circular hole to fix the flange in the appropriate position and ensure its stability before proceeding to the next process. Alternatively, depending on welding requirements, utilize the first and second folding structures, and through connecting blocks A7 / B15, connecting rods a8 / b16, and the folding structure (including the first folding part 10, the second folding part 11, and the wrench 23), to adjust the lengths of the telescopic rod 9 and the second telescopic rod 17 for welding. When one of the folding structures needs to be used, the wrench 23 can be used to fix or loosen the folding structure for horizontal use or to fold it inward at a 90° angle for storage. After use, store the tools on the shelf 2 to ensure the workbench is tidy.
