Fabricated built-in flexible water supply pipe

The utility model discloses an assembly type built-in flexible water supply pipe, and belongs to the technical field of built-in water supply pipes. The pipe comprises a main pipe body and an outer protection layer, the outer protection layer is arranged on the outer side of the main pipe body in a sleeving mode, an anti-deformation metal layer and a shaping metal layer are arranged between the outer protection layer and the main pipe body, the anti-deformation metal layer is tightly attached to the outer side of the main pipe body, and the shaping metal layer is tightly attached to the outer side of the anti-deformation metal layer. And the outer protection layer is tightly coated on the outer side of the shaping metal layer. According to the composite flexible water supply pipe, the anti-deformation metal layer and the shaping metal layer are arranged, and the anti-deformation metal layer adopts the circular torsion spring, so that when the whole composite flexible water supply pipe is bent and deformed und
