Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , the present invention provides a technical solution, including a drinking water steel pipe 1, a cylindrical connecting plate 2 is connected to one end of the drinking water steel pipe 1, a nut 7 is threadedly connected to the surface of the drinking water steel pipe 1, a rotating ring 8 is rotatably arranged on one side of the nut 7, a fixing structure 81 is connected to one end of the rotating ring 8, a sliding ring 9 is slidably arranged on the surface of the fixing structure 81, a limiting mechanism 91 is connected to one side of the sliding ring 9, an auxiliary mechanism 92 is connected to one end of the sliding ring 9, an L-shaped limiting circular rod 93 is rotatably arranged at one end of the sliding ring 9, and a valve 10 is slidably connected in the cylindrical connecting plate 2;

[0022] The fixing structure 81 includes a cylindrical rod 811, a plurality of second limiting grooves 812 are opened at one end of the cylindrical rod 811, a sliding block 813 is slidably arranged inside one end of the cylindrical rod 811, a sliding rod 814 is connected to one side of the sliding block 813, a first sliding groove 815 corresponding to the sliding block 813 is opened at one end of the cylindrical rod 811, a second sliding groove 816 corresponding to the sliding rod 814 is opened on one side of the cylindrical rod 811, a connecting rod 817 is rotatably arranged at one end of the sliding block 813, a fixing rod 818 is connected inside the first sliding groove 815, a solid rod 819 is connected to the opposite sides of the fixing rod 818, a gripping plate 820 is rotatably arranged at one end of the solid rod 819, and one end of the connecting rod 817 is rotatably connected to one side of the gripping plate 820;

[0023] The auxiliary mechanism 92 includes an auxiliary rod 921. One end of the auxiliary rod 921 is rotatably provided with an adjusting rod 922. One end of the adjusting rod 922 is rotatably provided with a force-applying rod 923. One end of the force-applying rod 923 is rotatably provided with a force-applying circular plate 924. One end of the adjusting rod 922 is provided with a sliding limit groove 925 corresponding to the rotating shaft of the auxiliary rod 921. The auxiliary rod 921 is rotatably arranged at one end of the sliding ring 9, and the adjusting rod 922 is rotatably arranged at one end of the cylindrical connecting plate 2.

[0024] One end of the cylindrical rod 811 is rotatably arranged on one side of the rotating ring 8. Its function is that when the auxiliary rod drives forward through the sliding ring, it will drive the adjusting rod. The adjusting rod rotates towards the force-applying rod, and the force-applying rod squeezes downward, so as to fix the valve more firmly at one end of the drinking water pipe.

[0025] The limiting mechanism 91 includes a plug rod 911 and a plug rod groove 912 opened in 9. One end of the plug rod 911 penetrates through the sliding ring 9 and is slidably arranged in the sliding ring 9 and the plug rod groove 912. A limiting ring 913 is connected to the surface of the plug rod 911. A spring 914 is connected to the top end of the limiting ring 913. A U-shaped limiting block 915 is connected to one end of the plug rod 911. A cross bar 916 is connected to the end of the plug rod 911 away from the U-shaped limiting block 915. Semi-circular handles 917 are rotatably arranged at both ends of the cross bar 916. Its function is that when the sliding ring reaches the specified position and fixes the valve, the sliding ring can be limited and fixed so that the sliding ring will not move.

[0026] A rubber pad 3 is connected to the inner side of the cylindrical connecting plate 2 corresponding to the valve 10. Its function is to further seal the valve so that no leakage will occur.

[0027] A limiting groove 1 5 is opened on one side of the drinking water steel pipe 1. A plurality of limiting rods 6 are connected in the limiting groove 1 5. Its function is to limit the limiting mechanism.

[0028] Both the fixing structure 81 and the auxiliary mechanism 92 are provided with four groups. Its function is to increase the firmness of the fixing of the valve by the fixing structure and the auxiliary mechanism.

[0029] A connecting hole is opened on one side of the cylindrical connecting plate 2 corresponding to the valve 10 and the cylindrical rod 811. Its function is to enable the umbrella-shaped fixing plate to enter the inside of the cylindrical connecting plate through the connecting hole to fix the valve.

[0030] Working principle: put one end of the valve 10 into the cylindrical connecting plate 2, then turn the rotating ring 8 forward and pull the semicircular handle 917. The semicircular handle 917 will drive the crossbar 916 and the plug rod 911 to move backward. The limiting ring 913 fixed on the surface of the plug rod 911 will squeeze the spring backward. The U-shaped limiting block 915 at one end of the plug rod 911 will also move backward as the semicircular handle 917 is pulled. The nut 7 and the sliding ring 9 will move forward with the forward movement of the rotating ring 8. When the sliding ring 9 moves forward, it will push the auxiliary rod 9 21 forward, when the auxiliary rod 921 is pushed forward, the central axis at one end of the auxiliary rod 921 will slide and rotate in the sliding limit groove 925. When the auxiliary rod 921 slides to the limit, it pushes the adjusting rod 922. The adjusting rod 922 and the cylindrical connecting disk 2 are rotationally connected. Due to the lever principle, the adjusting rod 922 will be squeezed inward, and the force rod 923 rotating on the other side of the adjusting rod 922 will be squeezed and continue to squeeze the force circular plate 924 inward. The force circular plate 924 will squeeze one end of the valve 10 to one side of the cylindrical connecting disk 2, and the sliding ring 9 reaches the limit, release the semicircular handle 917, and the spring 914 in the compressed state will be released to push the limit ring 913 forward. Since the insertion rod 911 and the limit ring 913 are connected, the insertion rod 911 and the U-shaped limit block 915 will also move forward. The U-shaped limit block 915 will be engaged with the limit rod 6 in the limit groove 5, which will play a role in limiting and fixing the sliding ring 9. At the same time, the umbrella-shaped fixing plate 820 in the closed state will extend into the rear of the connecting hole through the forward movement of the rotating ring 8, and then the sliding rod 81 will be toggled. 4. The sliding rod 814 will drive the connecting rod 817 on the side of the sliding groove 815 to move upward. One end of the connecting rod 817 is rotatably connected to one end of the umbrella-shaped fixing plate 820, and one side of the umbrella-shaped fixing plate 820 is rotatably connected to the solid rod 819. Therefore, the connecting rod 817 will open the umbrella-shaped fixing plate 820. After the umbrella-shaped fixing plate 820 is opened, the nut 7 is screwed backward. The nut 7 will move backward with the rotating ring 8 and the cylindrical rod 811. The umbrella-shaped fixing plate 820 will be firmly fixed on the side of the valve 10, thereby completing the steps of installing the valve.
