The inner mounting flange 1 includes a first flange plate and an annular protrusion disposed on the side of the first flange plate facing the outer mounting flange 2, the annular protrusion being spaced apart from the edge of the first flange plate. The outer mounting flange 2 includes a second flange plate and a flange formed on the edge of the second flange plate and extending toward the inner mounting flange 1. When the inner mounting flange 1 and the outer mounting flange 2 are connected, the outer wall of the annular protrusion contacts the inner wall of the flange to form a mounting groove located between the first flange plate, the annular protrusion, and the flange, and the O-ring 3 is disposed in the mounting groove. The sealing and limiting assembly also includes a limiting screw 4, which is disposed on the inner mounting flange 1 and penetrates the outer mounting flange 2.

[0019] The sealing and limiting assembly also includes a mounting screw 6 and a knob 8. The mounting screw 6 is located on the inner mounting flange 1 and passes through the outer mounting flange 2. The knob 8 is located on the side of the outer mounting flange 2 opposite to the inner mounting flange 1 and is screwed onto the mounting screw 6. The mounting screw 6 and the knob 8 are arranged in the middle of the inner mounting flange 1 and the outer mounting flange 2.

[0020] The limiting screw 4 passes through the first flange plate and the second flange plate in sequence, and the first nut 5 is screwed onto the limiting screw 4.
