[0003] When the bellows is used, a coating layer is formed on the surface of the pipe body by coating a heat insulation material (the material can be fluorinated ethylene propylene copolymer) to make the bellows have high-efficiency heat insulation performance. When the bellows is used, the bellows will be damaged under stress after being stretched to the limit, which will cause problems affecting the use of the bellows. UTILITY MODEL CONTENT

[0004] The utility model solves the technical problem that when the bellows is used, the bellows will be damaged under stress after being stretched to the limit, which will cause problems affecting the use of the bellows.
