The side of the sealing block 5 is also provided with a plurality of water outlet grooves 52. The water outlet grooves 52 are located at the second channel 41. A first sealing ring 10 is provided between the sealing block 5 and the joint tube 3 to prevent water from flowing into the gap between the joint tube 3 and the joint ring 4. A second sealing ring 11 and a third sealing ring 12 are provided between the sealing block 5 and the joint ring 4. The second sealing ring 11 and the third sealing ring 12 are located at both ends of the water outlet groove 52 to prevent water from flowing into the joint tube 3 and the joint gap. During assembly, the joint ring 4 is inserted into the rotating channel, and then the sealing block 5 is installed into the joint tube 3 to make the joint tube 3 sealed. The first sealing ring 10, the second sealing ring 11, and the third sealing ring 12 are tightened with the inner walls of the sealing block 5, the joint tube 3, and the joint ring 4, respectively. When in use, the first connecting pipe 1 is connected to the faucet body, and the second connecting pipe is connected to the water outlet. Water flows in from the first connecting pipe 1, then flows out from the first channel into the joint tube 3, then flows into the fluid channel 51 of the sealing block 5, then flows out from the water outlet groove 52, then flows into the second channel 41, and then flows out from the second connecting pipe 2. When in use, the user can adjust the angle of the second connecting pipe 2 by rotating the second connecting pipe 2, and then adjust the angle of the water outlet, so as to facilitate the use of the user. At the same time, when installed on the wash basin, the angle of the first connecting pipe 1 and the second connecting pipe 2 can also be adjusted to prevent the second connecting pipe 2 used for water outlet from interfering with the user when washing his hair or face, thereby hindering the user from washing.

[0028] In order to further fix the first connecting tube 1 and the second connecting tube 2, and prevent the joint ring 4 from being separated from the joint tube 3, a fixing column 7 is also included, a socket channel 53 is provided on the sealing block 5, the fixing column 7 is penetrated in the socket channel 53, a fixing channel 8 is provided between the fixing column 7 and the sealing block 5, and the fixing channel 8 penetrates the sealing block 5, the fixing column 7 and the sealing block 5 are connected by screw locking, and a fourth sealing ring 9 is provided between the fixing column 7 and the inner wall of the socket channel 53. The sealing block 5 is fixed in the joint tube 3 by screws, so as to prevent the joint from falling apart during use, thereby preventing the joint ring 4 from being separated from the joint tube 3, which is beneficial for long-term use by users.

[0029] In order to prevent the second connecting tube 2 from automatically falling back under the action of gravity after being rotated, a spherical end pin 13 is also included.

The second connecting pipe 2 is matched with a first boss 22 and a second boss 23 on the inner diameter of the first connecting pipe 25. The first boss 22 and the second boss 23 are penetrated in the first connecting pipe 25. The protrusions 24 are evenly distributed around the second boss 23. The protrusions 24 resist the inner wall of the first connecting pipe 25. A sealing ring is provided between the first boss 22 and the first connecting pipe 25 to prevent water leakage. The first connecting pipe 25 is also provided with a locking hole 251 for preventing the first connecting pipe 25 and the second connecting pipe 2 from detaching from each other. During installation, the other end of the first connecting tube 25 is directly inserted into the second connecting tube 2, and then the screws that prevent the first connecting tube 25 and the second connecting tube 2 from detaching are locked. Then the other end of the first connecting tube 25 is also connected through the above-mentioned joint, and the extension and lengthening of the water outlet pipe can be completed, so that the user can control the water outlet over a larger area and at a larger angle, making it more convenient for the user to use.
