A first clamping plate 202 is fixedly arranged at the output end of the hydraulic rod 201, and a second clamping plate 203 is arranged on the top of the workbench 1. The stainless steel welded pipe is clamped and fixed between the first clamping plate 202 and the second clamping plate 203. During use, the stainless steel welded pipe is inserted between the first clamping plate 202 and the second clamping plate 203, and the hydraulic cylinder is operated to drive the first clamping plate 202 and the second clamping plate 203 to clamp the stainless steel welded pipe, so as to clamp stainless steel welded pipes of different sizes, improve the clamping stability of the stainless steel welded pipe. And the above structure is a structure already existing in Chinese Patent [CN219746985U] and has been described in Chinese Patent [CN219746985U], so the present utility model will not elaborate on it here. A rotating assembly is arranged on the support column 2, and the rotating assembly includes:

[0026] A rotating unit, which is used to adjust the position of the end of the stainless steel welded pipe. The rotating unit includes a rotating shaft 3 and a connecting block 4. The rotating shaft 3 is rotatably connected to the support column 2, and one end of the rotating shaft 3 is fixedly connected to the outer wall of the hydraulic rod 201. By rotating the rotating shaft 3, the hydraulic rod 201 is driven to rotate, so that the rotating hydraulic rod 201 drives the first clamping plate 202 to rotate, and then drives the stainless steel welded pipe clamped on the first clamping plate 202 to rotate, facilitating the adjustment of the direction and position of the end of the cut stainless steel welded pipe;

[0027] A positioning unit, which is arranged on the outer wall of the rotating shaft 3 and is used to limit the use orientation of the first clamping plate 202 and the second clamping plate 203.
