Heating and ventilation pipeline cutting device for building heating and ventilation engineering

The utility model belongs to the technical field of building heating and ventilation engineering, and particularly relates to a heating and ventilation pipeline cutting device for building heating and ventilation engineering. A through opening communicating with the tail end of the limiting groove is further formed in the base and used for corresponding to a cutting part of the heating and ventilation pipeline; a material receiving assembly; the blocking plate stretches across the through opening and is installed on the top of the base, and the blocking plate is arranged to have the moving freedom degree in the horizontal direction and is used for positioning the cutting length of the heating and ventilation pipeline. According to the heating and ventilation pipeline cutting device, due to the fact that the material collecting assembly is arranged, the cut pipeline falls into the material collecting box, automatic material collecting after the pipeline is cut can be achieved, labor consumption is reduced, and
