Special structure capable of effectively reducing stress-strain value of compressor connecting pipeline

The invention discloses a special structure capable of effectively reducing stress-strain values of a compressor connecting pipeline, and relates to the technical field of compressor pipelines. The system comprises a compressor connecting pipeline; straight edge structures used for reducing stress strain are arranged at the two ends of each bent position in the compressor connecting pipeline. The bending angle of each bending part is not more than 90 degrees; the compressor connecting pipeline is a copper pipeline; the wall thickness of the copper pipeline is not less than 1mm; a metal plate fixing base is fixed to the straight edge structure, reaching the tail end of the third-time bending position, in the compressor connecting pipeline. And the metal plate fixing seat is flexibly connected with the straight edge structure through a flexible rubber hose or a rubber pad. The straight edge structures used for reducing stress and strain are arranged at the two ends of each bent position in the compressor connec
