The outer pipe is provided with a plurality of large hollow joint barrels and a plurality of small hollow joint barrels, the peripheral faces of the large joint barrels and the peripheral faces of the small joint barrels are arranged to be smooth, the large joint barrels and the small joint barrels are alternately sleeved outside the inner pipe and make contact with one another, and the largest cross sectional area of the large joint barrels is larger than that of the small joint barrels. Due to the fact that the inner pipe is wrapped by the outer pipe, the structure is not prone to aging and fracture, and service life is prolonged. The inner sides of the adjacent joint barrels squeeze mutually, the bending angle of the inner pipe is limited, and the inner pipe is not prone to fracture. Meanwhile, the large joint barrels and the small joint barrels are alternately sleeved outside the inner pipe, so that the whole hose pipe becomes inerratic and orderly, and appearance is more beautiful. The cross sectional areas of the large joint barrels are inconsistent with those of the small joint barrels, and therefore the whole hose pipe is layered better. Moreover, the peripheral faces of the large joint barrels and the peripheral faces of the small joint barrels are arranged to be smooth, so that the hose pipe is convenient to grab. Different decorative effects can be achieved through replacement of joint barrels in different shapes, and therefore the hose pipe is various in style. Even if the outer pipe is damaged, only the damaged joint barrel needs to be replaced, and therefore maintenance cost is low.
