Problems solved by technology

[0002] The existing knives and saws for cutting pipelines are linear on one side or both sides. When cutting the pipeline, the knife and the saw contact with the pipeline at one point, which is very inconvenient when cutting, and the cut section is not smooth. There have been pliers-structured pipe-cutting saws in the art, but they have technical problems such as easy damage and short service life, which limit their use, and the straight-line back and forth cutting method cannot solve the problem of uneven cutting planes. question

Abstract

The invention belongs to the technical field of pipeline cutting, and provides a cutter saw for cutting a pipeline. The cutter saw comprises two saw bodies which are symmetrically arranged, the corresponding ends of the two saw bodies are connected in a hinged mode, the other ends of the two saw bodies are each provided with a saw handle, the opposite sides of the two saw bodies are each providedwith a semicircular opening, the surface of each saw body is provided with a saw blade capable of sliding back and forth in the direction of facing the corresponding semicircular opening, arc-shaped saw teeth which are concaved inwards are arranged on the side, close to the corresponding semicircular opening, of each saw blade, and the other side of each saw blade is connected with a spring. The technical problems that in the prior art, pipeline cutting is inconvenient, and the cutting plane is not flat are solved.

Description

technical field [0001] The invention belongs to the technical field of pipe cutting, and relates to a knife saw for cutting pipes. Background technique [0002] The existing knives and saws for cutting pipelines are linear on one side or both sides. When cutting the pipeline, the knife and the saw contact with the pipeline at one point, which is very inconvenient when cutting, and the cut section is not smooth. There have been pliers-structured pipe-cutting saws in the art, but they have technical problems such as easy damage and short service life, which limit their use, and the straight-line back and forth cutting method cannot solve the problem of uneven cutting planes. question. Contents of the invention [0003] The invention proposes a knife saw for cutting pipes, which solves the above technical problems. [0004] Technical scheme of the present invention is realized like this: [0005] A knife saw for cutting pipes, comprising: [0006] The two saw bodies are s...
