And the positioning block 12 is fixedly connected to the first mounting ear 9. The jack 13 is opened on the second mounting ear 10 and the positioning block 12. The plug post 14 is slidably installed in the jack 13. By setting the jack 13, it is convenient for the plug post 14 to be slidably installed therein, and thus the auxiliary installation function can be achieved. The two threads 15 are opened on the outer surfaces of both sides of the plug post 14. The two nuts 16 are screwed on the two threads 15. The sealing cover 6 is hermetically installed at one end of the dark pipe 4. The water inlet pipe 5 is fixedly installed on the dark pipe 4. The external thread 22 is opened on the dark pipe 4. And the dark pipe 4 is connected to the internal thread in the second connecting pipe 2 through the external thread 22.

[0035] When in use, by inserting the two water collecting pipes 3 into the gap between the first connecting pipe 1 and the fourth connecting pipe 101, and then sleeving the first mounting sleeve 7 and the second mounting sleeve 8 on the first connecting pipe 1 and the water collecting pipe 3, at this time the positioning block 12 will be inserted into the corresponding positioning groove 11, and then the plug post 14 is inserted into the jack 13, and by rotating the nut 16, the fixed installation of the plug post 14 can be completed, and thus the connection between the first connecting pipe 1 and the water collecting pipe 3 can also be completed, improving the convenience and stability during connection;
