[0048] The working principle and usage process of the present utility model:

[0049] First, the operator places one section of the automotive pipeline to be welded on the top of the second support block 5, then starts the second pneumatic cylinder 8 to lower the second pressing block 9 to clamp the automotive pipeline. Then, according to the bending degree of the other section of the automotive pipeline, the operator starts the driving motor 401, causing the driving shaft 402 to drive the driving gear 403 to rotate. At this time, the driven gear 303 engaged with the driving gear 403 will drive the first support block 301 to rotate through the connecting rod 302 until the position angle of the first support block 301 matches the bending degree of the automotive pipeline. Subsequently, the operator places the automotive pipeline with a bending degree on the top of the first support block 301 and aligns the welding position with the already fixed automotive pipeline. Then, the operator starts the first pneumatic cylinder 305 to make the first pressing block 306 press the automotive pipeline with a bending degree. The mutual cooperation of each mechanism enables the first support block 301 to fixedly support automotive pipelines with different bending degrees without repeatedly disassembling and adjusting the first support block 301, thus facilitating the welding operation of the operator.

[0050] Immediately afterwards, the operator starts the power motor 18, causing the rotating shaft 19 to drive the rotating rod 20 to rotate, thereby generating a thrust on the outer surface of the exhaust duct 17 by the inner wall of the rotating rod 20, pushing the exhaust duct 17 with the collection box 12 to move along the inner surface of the operating table 2 until the smoking pipe 13 is aligned with the welding position. Subsequently, the operator starts the blower 15, enabling the fumes generated during the welding process to enter the collection box 12 from the smoking pipe 13 and be discharged from the exhaust duct 17 after being filtered by the activated carbon packet 14, thereby realizing the automatic collection and treatment of the fumes generated during the welding process.
