Adjustable PVC pipeline cutting device

The utility model discloses an adjustable PVC pipeline cutting device. The invention discloses an adjustable PVC pipeline cutting device. The device structurally comprises a meshing fluted disc, a cutter, an adjustable channel cutting device, a lower handle, a second connecting rod, a connecting pin shaft, a first connecting rod and an upper handle, the meshing fluted disc is mounted in the upperhandle in an embedded manner; the utility model discloses an adjustable PVC pipeline cutting device. An adjustable channel cutting device is arranged on the structure; pre-cutting, the arch state canbe gradually recovered; the pressure is continuously applied towards the interior and the bending is realized; and if the diameter of the pipeline is large, the pipeline can be bent outwards to be attached to the pipeline, then a cutting path is limited on the pipeline, the path is prevented from deviating in the cutting process, a vertical plane state can be cut out in the pipeline cutting process, and the matching rate i
