[0032] The first main water outlet pipe 4 and the first main water inlet pipe 12 are connected with the second main water outlet pipe 5 and the second main water inlet pipe 13 through the first clamping device, so that the core pulling holes to be reserved are communicated with each other, avoiding the need to specially use screws to block the core pulling holes, improving the assembly speed, reducing the leakage risk, and simplifying the structure of the valve core body.

[0033] In order to enable the faucet to have a water distribution function and facilitate the production of the water distribution valve seat 15, the water distribution valve seat assembly includes: a water distribution valve seat 15 communicated with the second main water outlet pipe 5, at least two water distribution outlet holes 16 opened on the water distribution valve seat 15, and water distribution outlet pipes 17 arranged on the water distribution valve seat 15 and respectively communicated with the water distribution outlet holes 16.

[0034] In order to enable the faucet to have the function of multi-terminal water outlet to meet the various needs of users, there are three water distribution outlet holes 16. The water distribution outlet pipes 17 are arranged in matching with the water distribution outlet holes 16, and a top spray water outlet 18, a shower water outlet 19 and a lower water outlet 20 are respectively arranged on the water distribution outlet pipes 17.

[0035] In order to further reduce the manufacturing difficulty and design difficulty of the production mold, the top spray water outlet 18 with a different orientation from the shower water outlet 19 and the lower water outlet 20 is separately produced.
