[0026] The curved foot outer sleeve 4 is provided with a curved foot inner tube 5, one end of the curved foot inner tube 5 is provided with a first external thread and the end is threadedly connected to the first internal thread provided on the inner wall of the first connecting tube 1 after passing through the curved foot outer sleeve 4; the inner wall of the other end of the curved foot inner tube 5 is provided with a wrench groove 502 for convenient wrench clamping and rotation; the outer side of the curved foot inner tube 5 is provided with a plurality of first sealing rings 7 along the axial direction of the curved foot inner tube 5 to achieve a sealing effect between the outer wall of the curved foot inner tube 5 and the inner wall of the curved foot outer sleeve 4.

[0027] One end of the first connecting tube 1 is integrally formed with a limiting protrusion 101, and four limiting protrusions 101 are provided, and the four limiting protrusions 101 are arranged at equal intervals along the circumferential direction of the first connecting tube 1; the inner wall of the curved foot sleeve 4 is provided with a limiting groove 401 adapted to the limiting protrusion 101, and when the curved foot sleeve 4 is sleeved on the outer side of the end of the first connecting tube 1, the limiting groove 401 is engaged with the limiting protrusion 101;

[0028] An annular protrusion 501 is integrally formed on the outer side of the end of the curved foot inner tube 5 away from the first connecting tube 1, and an avoidance groove 402 for avoiding the annular protrusion 501 is provided on the inner wall of the end of the curved foot outer sleeve 4 away from the first connecting tube 1; when the curved foot outer sleeve 4 slides relative to the first connecting tube 1, the annular protrusion 501 slides in the avoidance groove 402 and limits the sliding distance of the curved foot outer sleeve 4; the sliding distance of the curved foot outer sleeve 4 is greater than the length of the limiting protrusion 101 in the axial direction of the first connecting tube 1.

[0029] The matching structure of the annular protrusion and the avoidance groove can limit the range of movement of the curved foot outer shell to prevent it from detaching from the curved foot inner tube, thereby achieving the sliding and rotation effects of the curved foot outer shell and ensuring that the stable connection structure between the first connecting tube, the curved foot inner tube and the curved foot outer shell is not affected, further improving the use effect of the utility model.

[0030] The end of the first connecting tube 1 away from the curved foot sleeve 4 is provided with a curved foot nail 6 which can move in the first connecting tube 1 and limit the flow area of the water channel 201. The outer wall of the curved foot nail 6 is provided with a second external thread and is threadedly connected to the second internal thread provided on the inner wall of the end of the first connecting tube 1 through the second external thread.

After rotating to the required angle, slide the first connecting pipe relative to the curved foot sleeve in the opposite direction again so that the limiting protrusion re-engages with the limiting groove (as shown in FIG. Figure 3 As shown); it not only achieves the installation angle adjustment effect of the bent foot, but also avoids the bent foot from rotating again after the angle adjustment. The entire angle adjustment process can be operated without using a wrench, making the installation operation of the faucet more convenient and bringing convenience to the installation operation of the faucet;

[0035] On the other hand, the present invention adopts the design of a bent foot nail connected to the inner wall of one end of the first connecting pipe, so that the water flow state inside the entire bent foot can be controlled by adjusting the screw-in length of the bent foot nail, so that the bent foot can realize the control of water flow size and water flow opening, water flow closing and other states. Its operation is simple, convenient and fast, which further improves the use effect of the bent foot.
