[0032] like Figure 6 and Figure 7As shown, the male end 1 is provided with a hollow insertion part 14 on one side, and a third sealing ring 15 is arranged on the insertion part 14, and a side sealing is formed when the insertion part 14 is inserted into the insertion groove 6. A third chamber 16 is arranged on the other side, and a second sealing part is formed at the bottom of the third chamber 16, which is a first step 17. The second water stop part 41 comprises a hollow second water outlet part 19 connected with the second water stop part 18, and a second water passing groove 20 capable of communicating with the second water flow channel is arranged on the side wall of the second water outlet part 19. A second sealing ring 21 is arranged on the second water stop part 18, and the second water stop part 18 is arranged in the third chamber 16. A fourth step 22 is arranged at the outer end of the second sealing ring 21, and the second elastic member 39 is a spring arranged on the fourth step 22. Under the elastic force of the second elastic member 39, the second water stop part 18 is close to the first step 17, and the second sealing ring 21 is sealed on the end face of the fourth step 22, so as to close the second water flow channel.

[0033] As shown in Figure 1 and Figure 2 , after the male end 1 and the female end 2 are connected, the first water stop part 40 is pushed by the male end 1 and / or the second water stop part 41 to overcome the force of the first elastic member 12, so that the first water stop part 8 is away from the annular protruding part 3, so that the first water passing groove 10 is partially arranged in the first chamber 4, so as to form a water flow passage to make the first water flow channel through; and the second water stop part 41 is pushed by the first water stop part 40 to overcome the force of the second elastic member 39, so that the second water stop part 18 is away from the first step 17, so that the second water passing groove 20 is partially arranged in the third chamber 16, so as to form a water flow passage to make the second water flow channel through, so as to connect the whole water channel.

[0034] It should be noted that the female end 2 is a water inlet end, and the male end 1 is a water outlet end.

[0035] In this embodiment, as shown in Figure 2 , Figure 8 and Figure 9As shown, the female end 2 further comprises a clamping piece 23, which comprises a sliding part 24 and an operating part 25; the sliding part 24 is provided with a through hole 26 for the insertion part 14 to pass through; the lower part of the through hole 26 is formed with a clamping part 27.
