[0002] Copper pipe is also called red copper pipe. It is a kind of non-seam pipe pressed and drawn. Copper pipe has good electrical conductivity and thermal conductivity, and is the main material of electronic product's electrical accessories and heat dissipation accessories. It has become the first choice of modern contractors for installation of water supply pipeline, heating and refrigeration pipeline in all residential commercial buildings. Copper pipe has strong corrosion resistance and is not easy to oxidize. It is not easy to react chemically with some liquid substances and is easy to bend.

[0003] Through patent retrieval, it is found that the air conditioner copper pipe stretcher with publication number CN211915014U is provided with a guide wheel and a pipe groove. The semi-finished copper pipe passes through the pipe groove on the guide wheel until the pneumatic clamp clamps the semi-finished copper pipe. The two electric sliding tables alternately pull the semi-finished copper pipe to move to the right. The two guide wheels cooperate to extrude the semi-finished copper pipe, so that the semi-finished copper pipe is in a straight line. The first compression wheel and the second compression wheel uniformly extrude the semi-finished copper pipe, improving the quality of the finished copper pipe. However, it does not set a structure for placing the coiled copper pipe. When the coiled copper pipe is stretched, the coiled copper pipe may rotate, causing the surface of the coiled copper pipe to rub against the ground or other surfaces, causing the surface of the copper pipe to be damaged due to friction, reducing the production quality of the copper pipe, and making it relatively inconvenient to use.
