Combined helix tube

The invention discloses a combined helix tube. The combined helix tube comprises a tube body, wherein the tube body is a hollow threaded cylinder, and connection bases are mounted at two ends of the tube body; a tooth tip is arranged on each connection base and comprises a plurality of convex ends and a plurality of concave ends, insertion pieces are arranged at the convex ends, and slots are formed in the concave ends; the two adjacent connection bases are wrapped with a rubber layer. Accordingly, the helix tube adopting a combined structure is more convenient to extend and can meet requirements for different lengths. 本发明公开了种组合螺旋管，包括管体，所述管体为中空带有螺纹的圆柱体，所述管体两端安装有连接座；所述连接座上设有齿棱，所述齿棱上包括若干凸起端和若干凹进端，所述凸起端设有插片，所述凹进端设有插槽；两相邻的所述连接座外包裹层橡胶层。通过上述方式，本发明种组合螺旋管，该螺旋管采用组合结构，使得扩展更加的方便，可以适应不同的长度需要。
