It also features a movable lower connector 31, which can be rotated to a designated position to dispense water as needed, meeting more requirements. Furthermore, if the structure is not coaxial, the rotation will be stuck, not smooth, have a short lifespan, poor user experience, and be prone to leakage. Therefore, this utility model adopts a coaxial structure, making the rotation process smoother.

[0026] Please refer to the details. Figure 1 , 4 The faucet also includes a column 10, with the support assembly 20 located below it within the column 10. Specifically, the lower support base 21 is secured to the inside of the column 10 by several bolts. For example, three mounting platforms extending towards its central axis are provided inside the column 10, which can not only support the lower support base 21 but also be used to install it. The support base has a first through hole 213 for bolts to pass through, and the mounting platform has an internal threaded hole. The bolt passes through the first through hole 213 and is screwed into the internal threaded hole, thus realizing the installation and fixation of the lower support base 21.

[0027] Please refer to the details. Figure 2 , 45, 6, 7, 8, 9, Upper support seat 22 is fitted onto the outer side of the lower support seat 21 and locked to the lower support seat 21 by several first locking elements 24.

The lower water outlet channel 311 communicates with the inner side of the rotating part. The first sealing ring 50 includes a main body 51, which is an R-shaped sealing ring. The end face of the main body 51 is provided with a first groove 52, and the inner side is also provided with two annular steps. Specifically, a first annular groove 216 for the first sealing ring 50 is provided on the outer side of the lower support 21, above and below the water flow channel 211. The two first sealing rings 50 are respectively sleeved in the two first annular grooves 216, and the first grooves 52 face the water flow channel 211. When water is entering, the water flow is under low pressure, and the main body 51 can achieve a seal. When the water flow is under high pressure, the skirt of the R-type sealing ring provides a seal. At the same time, the inner wall of the R-type sealing ring has two semi-circular annular steps, which can be used for double-layer sealing. The inner wall friction provides a better sealing effect, smoother rotation, and longer service life.
