By adopting the technical scheme, the utility model has the beneficial effects that:

1. the utility model adopts a composite layer structure, wherein the conventional power tube is basically of a single-layer structure, namely the whole power tube is formed by adopting a single-layer single material, and the defect is that when the power tube is bent in a small amplitude, the bending part of the power tube is broken or locally cracked due to insufficient toughness or long-time bending state; and through adopting the composite bed structure, including inlayer, flexible supporting layer and skin, wherein inlayer is the same with current power tube, the toughness of pipeline can be strengthened to the flexible supporting layer of increase, connect inlayer and skin simultaneously, and its both sides all are provided with connecting portion, specifically be first connecting portion and second connecting portion, can strengthen the degree of fit between inlayer and the skin, simultaneously at the skin embedded connection net that is equipped with, the setting of connection net can follow inside reinforcing outer toughness, it can guarantee that the skin can not produce the fracture when the power tube takes place to bend, provide the supportability for it.

2. Through all adopt integrated into one piece ground setting up mode with first connecting portion and second connecting portion set up in on the flexible supporting layer, guaranteed its wholeness, can make its performance of connection better simultaneously.

3. Wherein first connecting portion adopts annular protruding, and the second connecting portion adopts annular groove to the respective interval that sets up is the same, and annular protruding and annular groove's setting purpose is compared in plane mechanism, and it can make flexible supporting layer possess better toughness, and when flexible supporting layer self toughness obtains promoting through the institutional advancement, its performance linking property that just can be better, and the holistic toughness of body also can obtain promoting.

4. The first connecting portion and the second connecting portion are all arranged obliquely to the axis of the pipe body, and because the inclined arrangement mode can ensure that the torsion received in the bending process is dispersed more uniformly and further improves the toughness of the pipe body compared with the arrangement mode perpendicular to the axis of the pipe body.

5. When the power tube only needs to be bent to a minimum extent, the first connecting portion and the second connecting portion are set to be opposite in inclination direction, and when the power tube needs to be bent to a greater extent, the first connecting portion and the second connecting portion are set to be identical in inclination direction, and therefore the power tube can be guaranteed to be in the best toughness state under the two conditions.
