10. A method for using a blanking tool for a pipeline intersection, which is applied to the blanking tool for the pipeline intersection according to any one of claims 1 to 9, and is characterized by comprising the following steps:
step 1, manufacturing a template paper cylinder with the radius the same as that of a branch pipeline, and adsorbing a vertical rod on the top of the outer wall of a main pipeline through a fixing piece;
step 2, adjusting the horizontal rotating rod to rotate to a direction parallel to the axis of the main pipeline and be locked by a first locking piece, and then adjusting two vertical telescopic rods, so that the vertical distance from the top scribing structure and the bottom scribing structure at two ends of the telescopic inner rod to the axis of the vertical rod is equal to the radius of the template paper tube, locking the telescopic outer rod on the horizontal rotating rod, ensuring that the telescopic outer rod cannot move, adjusting the tension of the elastic piece to a proper size, ensuring that the telescopic inner rod can slide freely up and down, and fixing the adjusting rod;
step 3, adjusting a supporting piece on the vertical rod to enable the supporting piece to support the template paper cylinder;
step 4, adjusting a top scribing structure and a bottom scribing structure at two ends of the telescopic inner rod, so that the top scribing structure just contacts the outer wall of the template paper cylinder, and adjusting the height and the bottom scribing structure of the telescopic outer rod, so that the bottom scribing structure just falls on the outer wall of the main pipeline;
step 5, holding a horizontal rotary rod by hand, rotating the horizontal rotary rod around the vertical rod for half a circle, sliding the telescopic inner rod downwards under the action of spring tension in the rotating process, ensuring that the top scribing structure and the bottom scribing structure do synchronous lifting motion in the rotating process, and leaving a closed curve on the outer walls of the main pipeline and the template paper cylinder after the rotation is completed, wherein the closed curve is an intersecting line requiring cutting and blanking before the collision of the main pipeline or the branch pipeline;
and 6, cutting the main pipeline along the upper closed curve of the main pipeline, blanking, sleeving the template paper cylinder on the branch pipeline, and cutting the branch pipeline along the upper closed curve of the template paper cylinder.
