[0010] Thereby, the movement of the two arc-shaped strips can be restricted. When the two arc-shaped strips move back and forth, they will pull the tightening ring to tighten, thereby tightening the rubber ring, thereby enhancing the sealing effect of the rubber ring; so that the sealing ring can be tightened conveniently, thereby having good sealing performance and avoiding leakage caused by the medium.

[0018] Depend on Figures 1 to 3 The utility model includes a mounting ring 1, a rubber ring 2 is fixedly mounted on the inner wall of the mounting ring 1, a tightening ring 3 is movably mounted inside the rubber ring 2, an opening 24 is opened on one side of the mounting ring 1, arc strips 5 are arranged on both sides of the opening 24, two sets of elastic clamping components are symmetrically arranged inside the opening 24, arc grooves 4 are opened on both sides of the inside of the mounting ring 1, the ends of the two arc strips 5 that are far away from each other extend to the inside of the arc groove 4, a plurality of limiting ratchet teeth 6 are fixedly mounted on one side of the two arc strips 5, and the arc strips 5 that are close to each other are arranged on the inner side of the mounting ring 1. A fixed connecting rod 10 is fixedly installed at one end, and a mounting plate 11 is fixedly installed at the end of the fixed connecting rod 10 away from the arc strip 5. A circular groove 12 is provided on the surface of the mounting plate 11.

[0019] During work, the operator puts his fingers into the circular holes 12 on the two mounting plates 11, and then pulls the fixed connecting rod 10 in opposite directions, thereby driving the two arc-shaped bars 5 to move toward the inside of the two arc-shaped grooves 4. When the arc-shaped bars 5 move, the positioning slide block 8 is driven by the fixed connecting block 7 to slide along the inside of the positioning slide groove 9, thereby increasing the stability of the arc-shaped bars 5 when moving. While the two arc-shaped bars 5 move, the movement of the two arc-shaped bars 5 is limited by the cooperation of the limiting ratchet 6 and the two elastic snap-fit ​​components. When the two arc-shaped bars 5 move backwards, they will pull the tightening ring 3 to tighten, thereby tightening the rubber ring 2, thereby enhancing the sealing effect of the rubber ring 2; this allows the sealing ring to be conveniently tightened, thereby having good sealing performance and avoiding leakage caused by the medium.

[0020] The two elastic clamping components each include a positioning shaft 13, the two positioning shafts 13 are respectively fixedly mounted on both sides of the inside of the opening 24, the surface of the positioning shaft 13 is rotatably mounted with a limit pawl 14, the two limit pawls 14 are respectively clamped with the limit pawls 14 on the two arc-shaped bars 5, the two limit pawls 14 are fixedly mounted on the side away from each other with a pull rod 22, and one end of the pull rod 22 is fixedly mounted with a pull ring 23; the two limit pawls 14 are fixedly mounted on the side away from each other and on the side of the pull rod 22 with a first rotating joint 15 A transmission rod 16 is rotatably installed on one side of the first rotating joint 15, and a second rotating joint 17 is rotatably installed on one end of the two transmission rods 16 that are away from each other.

[0021] When the two arc-shaped bars 5 move, they both drive the limit ratchet 6 to push the limit pawl 14. When the limit pawl 14 is pushed, the sliding sleeve 18 is driven by the transmission rod 16 to slide along the surface of the sliding rod 19, and at the same time, the spring 21 is squeezed. The elastic force of the spring 21 allows the limit ratchet 6 to move in the direction of the limit pawl 14. When the limit ratchet 6 moves in the opposite direction to the limit pawl 14, it will be limited by the limit pawl 14, thereby limiting the movement of the two arc-shaped bars 5.
