Because the utility model uses hard rubber C type ring 5 to replace screw to prevent adapter 1 from falling off from hole 20, so when assembling, do not need to twist the screw of small volume, can quickly assemble adapter 1 into hole 20, and can form the limit in the whole circumferential direction of adapter 1, to can greatly enhance the stability of adapter 1, further prevent it from falling off from hole 20, hard rubber sleeve 6 can prevent handle 10 from swinging in the process of rotation, greatly improve the operating stability and service life of faucet product.

[0025] As Figure 3 , 4 , 5, 7, 8, the outside wall of adapter 1 is provided with a first annular groove 11, and the inside wall of the hole 20 is correspondingly provided with a second annular groove 201, and the hard rubber C-shaped ring 5 is clamped between the first annular groove 11 and the second annular groove 201. The hard rubber C-shaped ring 5 is an open C-shaped ring with elasticity, and its cross section is a circular arc structure; when the opening of the hard rubber C-shaped ring 5 is tightened, the outer diameter D1 of the hard rubber C-shaped ring 5 is smaller than the inner diameter of the hole 20, and after the opening is loosened, the opening is opened under the action of its own elasticity, and the outer diameter D1 becomes larger and is smaller than the diameter D2 of the second annular groove 201. In this way, during assembly, the hard rubber C-shaped ring 5 is first fitted in the first annular groove 11, the opening of the hard rubber C-shaped ring 5 is clamped with the hand, and the adapter 1 is inserted into the hole 20 by pressing downward, then the hard rubber C-shaped ring 5 automatically opens and is clamped between the first annular groove 11 and the second annular groove 201, thereby preventing the adapter 1 from falling out of the hole 20, and the adapter 1 can also rotate very smoothly; in this way, the adapter 1 can be quickly installed in the hole 20 without screwing the screw, the installation efficiency is very high, and there is no need to punch holes on the side wall of the hole 20, which also helps to prevent moisture and dust from entering the inside of the hole 20 and corroding the valve element 3, thereby helping to prolong the service life of the valve element 3.

[0026] As Figure 2 , 3, 4, 5, 6, the adapter 1 is provided with a sleeve groove 12 for the hard rubber sleeve 6; the hard rubber sleeve 6 is rotatably sleeved on the sleeve groove 12, and the outer diameter D3 of the hard rubber sleeve 6 is greater than the outer diameter D4 of the adapter 1 and less than the inner diameter D5 of the hole 20. In this way, the hard rubber sleeve 6 is rotatably clamped between the adapter 1 and the inner wall of the hole 20, which can not only reduce the gap between the adapter 1 and the inner wall of the hole 20 to prevent the adapter 1 from swinging left and right when rotating, but also will not hinder the smooth rotation of the adapter 1.

[0027] As shown in Figure 2 , 3 , 4, 5, the first annular groove 11 and the sleeve groove 12 are arranged on the adapter 1 in an upper and lower side-by-side manner. In this way, during assembly, the hard rubber sleeve 6 is first placed into the hole 20, and then is encapsulated into the inside of the hole 20 under the limiting action of the hard rubber C-shaped ring 5.

[0028] As shown in Figure 6 , the hard rubber sleeve 6 is provided with a expansion joint 61 arranged along the height direction thereof. In this way, the hard rubber sleeve 6 can be expanded through the expansion joint 61, so as to be sleeved into the sleeve groove 12.

[0029] In order to further optimize the structure of the hard rubber sleeve 6, as shown in Figure 6 , a plurality of rotation protrusions 62 are arranged on the outer side wall of the hard rubber sleeve 6 in a circumferential direction, and the rotation protrusions 62 are arranged between the adapter 1 and the fixed sleeve 2; a recess 63 is arranged on the inner side wall of the hard rubber sleeve 6 and is integrally formed with the rotation protrusion 62, and the expansion joint 61 is preferably arranged on the rotation protrusion 62. In this way, the hard rubber sleeve 6 and the inner wall of the hole 20 are in contact through the rotation protrusion 62, and the contact area is greatly reduced; at the same time, the hard rubber sleeve 6 and the adapter 1 are in contact due to the existence of the recess 63, and the contact area between them is also greatly reduced, so that the friction force received by the adapter 1 during rotation is smaller, and the rotation is more smooth.

[0030] In order to facilitate the sleeving of the handle 10 and the adapter 1 together, as shown in Figure 2 , 4 , the bottom end of the handle 10 is provided with a sleeving protrusion 101, and the top surface of the adapter 1 is provided with a recess cavity 13 for sleeving the sleeving protrusion 101, and the sleeving protrusion 101 can be further bonded in the recess cavity 13 by using glue. In this way, the sleeving protrusion 101 is hidden in the recess cavity 13, and the connection between the handle 10 and the adapter 1 is completely hidden by the covering of the decorative cover 4, so that when the handle 10 is made of transparent materials such as crystal and glass, the connection between the handle 10 and the adapter 1 will not affect the overall transparency of the handle 10, so as to better reflect the material characteristics of transparent materials such as crystal and glass, and improve the product quality.

[0031] As shown inFigure 3 , 7 As shown, the valve core 3 has a valve core rod 31 with splined teeth at its top end, and the adapter 1 has a connecting chamber 16 with splined grooves at its bottom end. The valve core rod 31 is inserted into the connecting chamber 16, and the two are connected together by a splined structure. To further enhance the stability of the connection between the adapter 1 and the valve core rod 31, the fixing sleeve 2 has an annular protrusion 21 arranged circumferentially along its inner sidewall. The annular protrusion 21 surrounds and forms a hole 20, and the inner surface of the annular protrusion 21 is a smooth surface. In this way, the inner diameter of the hole 20 is smaller than the inner diameter of the fixing sleeve 2, greatly reducing the gap between the adapter 1 and the hole 20, and greatly reducing the thickness of the hard rubber sleeve 6 and the hard rubber C-ring 5, so that the adapter 1 can be installed more stably in the hole 20. Since the inner surface of the annular protrusion 21 is a smooth surface, the rotating part 1 can rotate very smoothly in the hole 20.

[0032] To enhance the internal sealing of this utility model, such as Figure 2 , 3 As shown in Figures 4 and 5, the outer wall of the adapter 1 is provided with a first rubber ring groove 14 that forms a sealing structure with the decorative cover 4, and a first rubber ring 15 fitted inside the first rubber ring groove 14. In this way, the first rubber ring 15 can not only form a sealing structure to prevent moisture and dust from entering the faucet, but also generate friction to form damping when the adapter rotates, thereby improving the user's feel.

[0033] like Figure 3 , 7 As shown, the outer wall of the fixed sleeve 2 is provided with a second rubber ring groove 22 that forms a sealing structure with the decorative cover 4, and a second rubber ring 23 embedded in the second rubber ring groove 22. In this way, the second rubber ring 23 can form a sealing structure between the fixed sleeve 2 and the decorative cover 4 to prevent moisture and dust from entering the faucet, and the elastic pressure of the second rubber ring 23 can make the decorative cover 4 fit very tightly on the fixed sleeve 2.

[0034] Furthermore, such as Figure 3 , 7 As shown, the outer wall of the fixing sleeve 2 is also provided with an extension 26. During installation, the fixing sleeve 2 is fixed to the countertop through the extension 26. The bottom surface of the extension 26 is provided with a third rubber ring groove 24 and a third rubber ring 25 embedded in the third rubber ring groove 24. This can prevent hard contact between the fixing sleeve 2 and the countertop when fixing the fixing sleeve 2 to the countertop, prevent damage to the countertop, and form a sealing structure to prevent water and dust from entering the faucet.
