A moving ring 6 is sleeved on the outer surface of the fixing ring 4, and an arc-shaped toggle block 7 is symmetrically installed on the outer surface of the moving ring 6. A plurality of cavities 8 are provided inside the moving ring 6, and a moving block 10 is slidably connected inside the cavity 8. A pull rod is installed at one end of the moving block 10, and the pull rod passes through the moving ring 6 and is installed with a pull ring. A spring 11 is sleeved on the outer surface of the pull rod, and a blocking block 12 is installed at the other end of the moving block 10, and the blocking block 12 passes through the cavity 8. The upper end surface of the blocking block 12 is an arc surface, and the inner wall of the cavity 8 is symmetrically provided with a matching groove 9, and the matching groove 9 is slidably connected to the matching groove 9. The block 13 is fixedly connected to the moving block 10 by the matching block 13. The moving block 10 is pulled by the pull ring and the pull rod to move the compressed spring 11. The moving block 10 drives the blocking block 12 to retract into the cavity 8. Then, the assembly ring 19 of the pipe 18 can be quickly removed. A number of grooves 14 are provided on the inner wall of the moving ring 6. A guide rod 15 is installed inside the groove 14. A slider 16 is sleeved on the outer surface of the guide rod 15, and the slider 16 is fixedly connected to the outer surface of the fixed ring 4. A spring 2 17 is sleeved on the outer surface of the guide rod 15, and the spring 2 17 is located above the slider 16. Pipes 18 are provided on both sides of the valve body 1.

The blocking block 12 compresses the spring 11. When the assembly ring 19 is stuck in the inside of the fixed ring 4 and the assembly ring 19 leaves the blocking block 12, the blocking block 12 loses its limiting force, and the movable block 10 is pushed to reset by the spring 11. The movable block 10 drives the blocking block 12 to reset and block one end of the assembly ring 19, thereby quickly installing the valve body 1.
