[0025] During the use of this solution, the extrusion screw 9 is first rotated to move upward, driving the sliding plate 10 and the three plug rods 11 to move upward, separate from the three slots 12 at the initial position, and loosen the sealing fixation of the three sealing sleeves 6, so that the staff can pull the three sealing sleeves 6 and the active air pipe 7 to perform synchronous telescopic movement. After moving to the appropriate length, the movement is stopped, and the extrusion screw 9 is rotated downward again to drive the sliding plate 10 and the three plug rods 11 to move downward, pass through a pair of jacks, and extend to the corresponding slots 12 below for insertion, so that the three sealing sleeves 6 and the active air pipe 7 are limited and fixed after the adjustment is completed to keep them stable, so as to achieve the appropriate length adjustment of the three active air pipes 7 according to the use requirements, without changing the cutting torch with different air pipe specifications for use, reducing the use cost and enhancing the use effect.
