BACKGROUND OF THE INVENTION 
     This utility model relates to a diversion conduit and particularly to a diversion conduit commonly used for irrigating the greening. 
     There are a variety of irrigation systems for existing flower beds, lawns and other greening facilities. One of them is to use a diversion conduit to connect the water tap for irrigation; this kind of irrigation system is most common and simple to construct with low cost, and finds the widest application. However, practice finds that the difference between the conduit body and the connector in material and structure renders the conduit body venerable to fracture at the connection with the connector, and that the connection between the conduit body and the connector is a fixed and dead connection. Once the conduit body fractures, the entire diversion conduit will be useless, causing great waste. 
     It shows that the above existing diversion conduit is obviously in convenient and imperfect in structure and use, which requires further improvement. It is also one of the significant improvement objectives to develop a newly structured diversion conduit that is structurally simple and convenient to use with detachably connected conduit body and connector so that once the conduit body fractures, its use can be restored.

     The purpose of this utility model and solution to its technical problem can be further achieved by the following technical solutions. 
     As to the aforementioned diversion conduit, the said external cap includes internal threads and internal projection. The minor diameter of the internal thread is smaller than the external diameter of the conduit body, and the internal diameter of the internal projection is almost equal to the external diameter of the conduit body. The internal calipers include external threads and external projection. The external threads match the internal threads of the external cap. The external projection has a trapeziform axis cross section; the external diameter of its end is slightly smaller than the internal diameter of the conduit body while the external diameter of its bottom is slighter greater than the internal diameter of the conduit body. The external cap and the internal calipers are bolted. The end of the conduit body is clamped by the internal projection of the external cap and the external projection of the internal calipers. 
     As to the aforementioned diversion conduit, the water intake connector comprises a butterfly cap connected via locking piece with the internal calipers of the water intake connector. 
     As to the aforementioned diversion conduit, the said water intake connector is provided with internal threads and the butterfly cap provided with a projection at the connection with the internal calipers. The end cap of the locking piece is tightly appressed to and bolted with the calipers projection.
