Corrosion-resistant metal hose

The utility model discloses a corrosion-resistant metal hose which comprises a sleeve, a polytetrafluoroethylene hose is arranged in the middle of the inner side of the sleeve, a spring coil is arranged between the sleeve and the polytetrafluoroethylene hose, fixing heads are arranged at the two ends of the spring coil, and the polytetrafluoroethylene hose and a connector are glued together. The corrosion-resistant metal hose solves the problems that an existing metal hose is poor in corrosion resistance, the service life of the metal hose is affected, a corrosion-resistant lining is arranged in some metal hoses, but when the hose is bent, the lining can be broken, and normal use of the metal hose is affected. The structure of the metal hose is improved and optimized, the polytetrafluoroethylene hose is installed in the metal hose, the corrosion resistance of the metal hose can be effectively improved through the polytetrafluoroethylene hose, and meanwhile the spring is arranged on the inner side of the metal
