[0030] Specifically, the first pipe body includes a straight pipe section 211 and an arc-shaped pipe section 212. The first end of the straight pipe section 211 is inserted into the main outlet, and the second end of the straight pipe section 211 is connected to the first end of the arc-shaped pipe section 212. The second end of the arc-shaped pipe section 212 is provided with a first outlet nozzle 213. The first end of the straight pipe section 211 is provided with an external thread, and the inner wall of the connecting sleeve is provided with an internal thread that is threadedly connected to the external thread.

[0031] In some embodiments, the faucet further includes a quick-connect fitting 32, and the secondary water outlet assembly 22 is interconnected with the corresponding secondary water outlet through the quick-connect fitting 32; the secondary water outlet assembly 22 includes a third pipe body, a second valve 222, and a second water outlet 221. The outer wall of the third pipe body has a large-diameter section 225 and a small-diameter section 224.
