[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. In the utility model, when the external pipeline does not have a corresponding flange, the open end of the connecting pipe is abutted against the open end of the external pipeline, and the lap ring is sleeved on the outside of the external pipeline.
