An internal hexagonal bolt 11 is arranged inside the outer housing 12. Rotating the internal hexagonal bolt 11 from the outside can drive the connecting rod 14 to rotate, which is convenient for the worm 13 to rotate, thereby driving the worm gear 15 to rotate the rotating base ring 16. The first flat thread 17 inside the rotating base ring 16 meshes with the second flat thread 20 on the outer side of the movable tongue 18, so that the movable tongue 18 moves in the movable cavity 19 and approaches the wedge-shaped ring groove 6, so that multiple flanges are interlocked and fixed with each other, which is convenient for the installation of the flanges. One end of the internal hexagonal bolt 11 is fixedly provided with a connecting rod 14. A worm 13 is fixedly arranged on the outer side of the connecting rod 14. A rotating base ring 16 is rotatably arranged inside the socket pipe sleeve 10. A worm gear 15 is fixedly arranged on the outer side of the rotating base ring 16. The clamping mechanism 4 includes a plurality of movable tongues 18 which are arranged at equal intervals inside the socket pipe sleeve 10. A wedge-shaped ring groove 6 is opened on the outer side of the connecting pipe 1 away from the socket pipe sleeve 10. The wedge-shaped ring groove 6 cooperates with the movable tongue 18 to fix the flanges to each other;

[0034] An activity cavity 19 is opened at a position of the socket pipe sleeve 10 near the second flat thread 20. A first flat thread 17 is arranged inside the rotating base ring 16. A second flat thread 20 is arranged on one side of each of the plurality of movable tongues 18 close to the worm gear 15. The first flat thread 17 cooperates with the second flat thread 20, which is convenient for the rotating base ring 16 to drive the movable tongue 18 to move when rotating;

[0035] A sealing ring 3 is fixedly arranged at a position inside the connecting pipe 1 near the socket pipe sleeve 10. The sealing ring 3 is used to improve the connection tightness between multiple flanges. A wedge-shaped surface 9 is arranged on one side of each of the plurality of movable tongues 18 close to the wedge-shaped ring groove 6. The wedge-shaped surface 9 is convenient to fit with the position of the wedge-shaped ring groove 6, which is convenient for installation. The worm gear 15 and the worm 13 are meshed, which is convenient for the worm 13 to drive the worm gear 15 to rotate. A rear opening 8 is arranged on one side of the connecting pipe 1 close to the wedge-shaped ring groove 6. A front opening 7 is arranged on one side of the connecting pipe 1 close to the socket pipe sleeve 10. The front opening 7 and the rear opening 8 cooperate with each other, which can facilitate the flow of the substance to be conveyed inside the flange. Each of the plurality of movable tongues 18 is clamped inside the wedge-shaped ring groove 6. The movable tongue 18 cooperates with the wedge-shaped ring groove 6, which is convenient for the installation of multiple flanges.

[0036] Working principle: Slip the sleeve 10 over one end of the connecting pipe 1 near the wedge-shaped ring groove 6, with the position of the movable tongue 18 corresponding to that of the wedge-shaped ring groove 6. Rotate the hexagon socket head bolt 11 to rotate within the outer housing 12, causing the hexagon socket head bolt 11 to drive the connecting rod 14 to rotate, thereby driving the worm 13 to drive the worm gear 15 to rotate. The first flat thread 17 on the inner side of the rotating base ring 16 meshes with the second flat thread 20 on the outer side of the movable tongue 18, causing the rotating base ring 16 to drive multiple movable tongues 18 to move. The multiple movable tongues 18 move towards the inner side of the wedge-shaped ring groove 6 and fit against the outer side of the connecting pipe 1. The sealing ring 3 is used to improve the connection tightness between multiple flanges. The wedge surface 9 facilitates fitting with the position of the wedge-shaped ring groove 6, thereby enabling the mutual installation of multiple flanges.
