The first notch 101 is on the outer peripheral surface of the mating end, the first notch 101 may be configured as a rectangular opening, the first bottom wall surface 101a is a bottom wall surface of the first notch and is disposed inside the first notch, the second notch 102 is also disposed at the mating end, the second notch 102 and the first notch 101 are sequentially arranged in a radial direction of the mating end, the second notch 102 is also configured as a rectangular shape, the second notch 102 has four wall surfaces, wherein a wall surface close to one side of the first notch 101 is a second bottom wall surface 102a, the second bottom wall surface 102a is disposed adjacent to the first bottom wall surface 101a, and the first bottom wall surface 101a and the second bottom wall surface 102a are gradually overlapped when the mating end is stressed, that is, when the mating end is tightly hooped, so as to reduce the diameter of the mating end, tighten the mating end, and improve the tightness of the pipeline connection structure.
The first bottom wall surface 101a and the second bottom wall surface 102a may be on the same straight line, so as to be suitable for narrowing the width of the first notch 101 and the width of the second notch 102 gradually when the connecting pipeline 120 is tightened, and the first bottom wall surface 101a and the bottom wall surface are overlapped gradually, thereby ensuring that the aperture of the connecting pipeline 120 is variable.
