An installation groove 7 is provided on the surface of the connecting pipe 2. A fixing sleeve 4 is provided on the surface of the installation groove 7. A T-shaped sliding groove 10 is provided at the upper end of the connecting pipe 2, and a T-shaped slider 11 is provided in the T-shaped sliding groove 10. A thread 2 18 is provided on the surface of the connecting seat 3, and a thread 1 8 is provided on the surface of the fixing sleeve 4.
[0022] When needed, align the connecting tube 2 6 with the connecting seat 3 and insert it. Then push the fixing sleeve 4 towards the connecting seat 3. The connecting seat 3 has a second thread 18 and the fixing sleeve 4 has a first thread 8. Rotate the fixing sleeve 4 to fix the connecting seat 3 and the fixing sleeve 4 by threading them together. Manually push the T-shaped slider 11 to slide it in the T-shaped groove 10. The T-shaped slider 11 compresses the spring 15, causing the spring 15 to contract in the T-shaped groove 10. At this time, the limiting posts 13 on both sides of the T-shaped slider 11 pass through the through hole 19 and are inserted into the limiting groove 14. Rotate the clamping plate 17 to clamp the clamping plate 17 into the clamping groove 12 to fix the T-shaped slider 11. At this time, the limiting posts 13 inserted into the limiting groove 14 can strengthen the connection between the shut-off valve body 1 and the connecting tube 2 to a certain extent and prevent loosening after long-term use.
[0023] Example 2: Based on Example 1, in order to facilitate the fixing of the connecting pipe 1 2, a retaining ring 5 is fixedly connected to one side wall of the connecting pipe 1 2, and a connecting pipe 2 6 is fixedly installed inside one end of the retaining ring 5. A rubber gasket is provided on one side wall of the retaining ring 5; the thread 1 8 is provided inside the fixing sleeve 4, and a limiting ring 9 is fixed inside the fixing sleeve 4. The limiting ring 9 is slidably installed on the mounting groove 1 7, and a limiting groove 14 is opened on the surface of the limiting ring 9.
[0024] Insert the connecting tube 2 6 into the connecting seat 3, and then push the fixing sleeve 4 towards the connecting seat 3. The connecting seat 3 has a second thread 18 and the fixing sleeve 4 has a first thread 8. Rotate the fixing sleeve 4 to fix the connecting seat 3 and the fixing sleeve 4 by threading them together. A rubber gasket is provided on one side wall of the retaining ring 5, which plays a certain sealing role in the connection between the connecting tube 2 and the connecting seat 3.
[0025] Example 3: Based on Example 2, in order to facilitate the reinforcement of connecting pipe 12, T-shaped slider 11 is slidably installed in T-shaped groove 10. Spring 15 is provided in T-shaped groove 10. One end of spring 15 is fixedly installed on the side wall of T-shaped slider 11, and the other end of spring 15 is fixedly installed on the inner side wall of T-shaped groove 10.

The bottom ends of the two sets of fixing blocks 16 are fixedly installed on the upper surface of connecting pipe 12. A clamping plate 17 is rotatably installed between the two sets of fixing blocks 16.
[0026] Manually push the T-shaped slider 11 to make it slide within the T-shaped groove 10. The T-shaped slider 11 compresses the spring 15, causing the spring 15 to contract within the T-shaped groove 10. At this time, the limiting posts 13 on both sides of the T-shaped slider 11 are inserted into the limiting groove 14 through the through hole 19. Rotate the clamping plate 17 to clamp it into the clamping groove 12, thus fixing the T-shaped slider 11. At this time, the limiting posts 13 inserted into the limiting groove 14 can strengthen the connection between the shut-off valve body 1 and the connecting pipe 2 to a certain extent.
[0027] In actual use, align the connecting pipe 2 6 with the connecting seat 3 and insert it. Then push the fixing sleeve 4 towards the connecting seat 3 to fix the connecting seat 3 and the fixing sleeve 4 with a threaded connection. Manually push the T-shaped slider 11 to slide it in the T-shaped groove 10. The T-shaped slider 11 compresses the spring 15. At this time, the limiting posts 13 set on both sides of the T-shaped slider 11 pass through the through hole 19 and are inserted into the limiting groove 14. Rotate the clamping plate 17 to clamp the clamping plate 17 into the clamping groove 12 to fix the T-shaped slider 11. At this time, the limiting posts 13 inserted into the limiting groove 14 can strengthen the connection between the shut-off valve body 1 and the connecting pipe 2 to a certain extent and prevent loosening after long-term use.
