The rotation of the operating ring 2 drives the trapezoidal block 3 to move through the threaded connection, so that the first arc plate 5 and the second arc plate 6 press the outer wall of the pipeline hose as the trapezoidal block 3 moves. At this time, the first arc plate 5 and the second arc plate 6 cooperate with the first annular groove 7 and the second annular groove 8 respectively to compress and seal the pipeline hose.
