[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model enables the first sealing ring to push the second sealing ring by mutual contact between the second chamfer on the second sealing ring and the first chamfer on the first sealing ring, so as to reduce the gap and push the second sealing ring to move by mutual extrusion between the second sealing ring and the first sealing ring; and enables the third chamfer on the second sealing ring to contact with the third chamfer on the third sealing ring so that the second sealing ring pushes the third sealing ring to extend when moving, thereby reducing the distance between the two flange rings.
