Further, the connection part of described first hook and second hook is skewed.
Further, the afterbody of described first hook and second hook is equipped with the firm circle of fastening and returns hook structure.
Further, described metal tube is a circular hollow tube.
Further, described sealing layer is the smooth circular hollow tube of inner tubal wall.
Further, described elastic protective layer is the circular hollow tube of wave-like type for outer tube wall.
Further, described sealing layer adopts the high resilience sealing material to make; Described elastic protective layer adopts the high resilience material to make.
The mutual sleeve pipe of metal described in the utility model can adopt stainless steel belt or Galvanized Steel Strip, corrosion resistance and good.
Elastic protective layer described in the utility model adopts the high resilience material, and section configuration is wave-like type, has guaranteed wear-resisting, the anti-bending strength of metallic hose, and has further improved the bearing capacity of metallic hose.Described sealing layer adopts the high resilience sealing material, guaranteed the sealing of metallic hose, and inner tubal wall is smooth, can reduce the flow resistance of fluid in pipe, reduces the pressure loss, improves efficiency of transmission, and prolongs the working life of metallic hose.
