The installation process of the water faucet is as follows:

when the user selects to install the limit option member 30 and the clockwise and counterclockwise rotation angle ranges are the same:

firstly, the valve seat 40 is arranged in the assembly cavity 12, the valve core 50 is arranged in the side cavity 13, and the valve seat 40 and the valve core 50 are fixed with the tap body 10 through the gland 60;

then, the two sealing rings 23 are sleeved on the periphery of the plug-in connector 21, the two second limiting parts 82 are symmetrically arranged by taking the first limiting part 81 as a center, the position of the limiting optional part 30 is adjusted, the limiting optional part 30 is sleeved on the periphery of the limiting driving part 22, and then the positioning part 25 is installed to axially position the limiting optional part 30; then, the plug 21 is inserted into the water outlet channel 43 from the opening of the rotation cavity 11, and at this time, the first position-limiting part 81 is located at the center of the two second position-limiting parts 82, which may be the center of the first space 821 or the center of the second space 822, with actual requirements as the standard;

then, the rotating sleeve 70 is fitted into the top end of the rotating chamber 11, and the positioning screw 71 is screwed into the screw hole 16 to press the end of the positioning screw 71 against the outer periphery of the plug 21, thereby completing the installation of the nozzle 20.

When the user selects to install the limit option part 30, and the clockwise and counterclockwise rotation angle ranges are different:

in the same manner, only when the position of the limiting optional part 30 is adjusted, the two second limiting parts 82 are not symmetrically arranged around the first limiting part 81, taking fig. 10 as an example, when the clockwise rotation angle of the water outlet nozzle 20 is required to be greater than the counterclockwise rotation angle, only the left second limiting part 82 needs to be close to the first limiting part 81, and correspondingly, the right second limiting part 82 is far away from the first limiting part 81.

When the user does not need to install the bump selector 30:

after the valve seat 40 and the valve core 50 are assembled according to the above steps, the plug 21 is inserted into the water outlet passage 43 from the rotation chamber 11, and then the rotation bushing 70 and the positioning screw 71 are installed to position the water outlet nozzle 20.

The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
