[0022] More specifically, the connection assembly 4 is connected and sealed by setting the joint assembly 3. When in use, the threaded tube 35 is first connected to the left thread of the valve body 12 by rotating, and then the fixing nut 32 is rotated so that the square positioning groove 33 on its surface is perpendicular to the card seat 22, and then the rotation is stopped. At this time, the first threaded rack 26 is rotated, and the first threaded rack 26 is separated from the inner cavity of the card slot 23. Under the action of gravity, the card seat 22 is inserted into the interior of the fixing nut 32 through the square positioning groove 33. Then, the first threaded rack 26 is rotated in the opposite direction, and the first threaded rack 26 passes through the card slot 23 to the interior of the card seat 22, thereby fixing the card seat 22. After the holder 22 is fixed, the fixing nut 32 is fixed to prevent it from moving.

Then, under the action of the second sealing ring 42, the gap generated at the joint between the inner cavity of the second joint 41 and the first joint 31 is sealed. Finally, the second threaded rack 36 is rotated, and the second threaded rack 36 passes through the fixing groove 43 to the interior of the second joint 41, thereby fixing it, which has the advantages of good sealing effect and simple operation.
[0023] In some embodiments, the instrument body 11 is connected to the right side of the valve body 12, the L-shaped frame 21 is fixedly installed on the left side of the top of the valve body 12, the through groove 27 is opened inside the L-shaped frame 21, and the holder 22 is arranged inside the through groove 27. More specifically, the valve body 12 is provided to control its fluid, and the through groove 27 is provided to accommodate the holder 22.
[0024] In some embodiments, the positioning block 25 is fixedly installed on the top of the L-shaped frame 21, the first threaded frame 26 is rotated inside the positioning block 25 through threads, and the card slots 23 are evenly opened on both sides of the inner cavity of the card holder 22.

[0025] In some embodiments, the positioning rod 24 slides in the inner cavity of the holder 22, and the two sides of the positioning rod 24 are fixedly connected to the inner cavity of the through groove 27. The fixing nut 32 is fixedly installed on the right side of the first joint 31, and the threaded tube 35 is connected to the right side of the first joint 31. More specifically, the holder 22 is limited by setting the positioning rod 24 to prevent the holder 22 from shaking during movement. The threaded tube 35 and the first joint 31 are rotated mainly by a wrench by setting the fixing nut 32.
[0026] In some embodiments, the inner cavity of the fixing nut 32 is fixedly connected to the surface of the threaded tube 35, the annular groove 34 is evenly opened on the surface of the fixing nut 32, and the square positioning groove 33 is opened on the front of the fixing nut 32 and there is only one of them. More specifically, the annular groove 34 is provided mainly to highlight the existence of the square positioning groove 33. The square positioning groove 33 is provided not only to identify the fixing nut 32, but also to fix the fixing nut 32.

More specifically, by setting the fixing groove 43, the inner side of the second threaded rack 36 is limited to further fix the second joint 41.
[0029] Working principle:
[0030] Step 1: When in use, first rotate the threaded tube 35 to connect it to the left side of the valve body 12 by threading. Then, rotate the fixing nut 32 until the square positioning groove 33 on its surface is perpendicular to the clamping seat 22, and then stop rotating. At this time, rotate the first threaded rack 26, and the first threaded rack 26 will be separated from the inner cavity of the clamping groove 23. Under the action of gravity, the clamping seat 22 will be inserted into the interior of the fixing nut 32 through the square positioning groove 33. Then, rotate the first threaded rack 26 in the opposite direction, and the first threaded rack 26 will pass through the clamping groove 23 and penetrate into the interior of the clamping seat 22, thereby fixing the clamping seat 22.
[0031] Step 2: After the base 22 is fixed, fix the fixing nut 32 to prevent it from moving. When fixing the connecting component 4, you only need to quickly insert the second joint 41 into the inner cavity of the first joint 31, and seal the gap between the second joint 41 and the first joint 31 under the action of the first sealing ring 37. Then, under the action of the second sealing ring 42, seal the gap at the joint between the inner cavity of the second joint 41 and the first joint 31. Finally, rotate the second threaded rack 36, and the second threaded rack 36 passes through the fixing groove 43 to the interior of the second joint 41, thereby fixing it, which has the advantages of good sealing effect and simple operation.
