[0002] PVC pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the earliest plastic pipe developed and applied. PVC is its abbreviation. The main component is polyvinyl chloride. Other ingredients are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive.

[0003] Before connecting the PVC pipe, you need to trim both sides of the pipe, remove the burrs on the pipe mouth, and then apply glue before connecting.

[0012] Furthermore, fixing rings are provided inside the fixing clamp and the sliding clamp.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can drive the threaded screw to rotate by setting a screw motor, so that the movable platform can move on the surface of the threaded screw, drive the fixed PVC pipe to move, so that both ends of the PVC pipe can contact the trimming grinding wheel, so that the PVC pipe can be trimmed. At the same time, due to the movement of the movable platform, the trimming direction can be changed without disassembling the PVC pipe, which simplifies the trimming steps and improves the trimming efficiency.

[0015] 2. The movement of the sliding clamp can be controlled by adjusting the knob, so that it cooperates with the fixed clamp to fix the PVC pipe. At the same time, PVC pipes of different sizes can be fixed through the fixing ring. BRIEF DESCRIPTION OF THE DRAWINGS
