Cutting equipment for water supply and drainage engineering pipeline

The utility model discloses cutting equipment for a water supply and drainage engineering pipeline, and relates to the technical field of pipeline cutting equipment. A supporting rod is fixedly arranged on the upper surface of the machining plate, a top plate is fixedly arranged at the upper end of the supporting rod, a side plate is fixedly arranged on one side of the top plate, an electric telescopic rod is fixedly arranged on the upper surface of the side plate and the upper surface of the top plate, a convex plate is arranged at the output end of the electric telescopic rod, and a penetrating groove is formed in the upper surface of the top plate. A pipeline needing to be machined can be inserted between the circular clamping blocks, then the driving motor can be started to drive the screw rod at the output end to rotate, so that the first rotating block matched with the screw rod can move, the supporting disc can be driven to rotate, the supporting disc rotates to enable the sleeve plate connected to the
