Cutting device for heat pump accessory machining

The cutting device for heat pump accessory machining comprises a fixing plate, a connecting plate is fixedly installed at the front end of the fixing plate, a fixing ring is fixedly installed at the front end of the connecting plate, an arc-shaped groove is formed in the surface of the fixing ring, and a connecting rod is connected into the arc-shaped groove in a sliding mode. According to the pipeline cutting device, the exterior of a pipeline is fixed through the outer limiting plate, the interior of the pipeline is fixed through the inner limiting plate, the cutting positions of the pipeline through the outer limiting plate and the inner limiting plate are located on the left side and the right side of the position to be cut, and the situation that the pipeline shakes in the cutting process is avoided; therefore, the situation that a cutting line is uneven due to the fact that the pipeline shakes during cutting is avoided, and the sealing performance and the connectivity of the pipeline are not affected; a
