Furthermore, the stability of the engaging ring 32 can be improved, so as to prevent the sealing column 31 from loosening and improve the stability of the sealing column 31. Since installation grooves 33 are provided at the middle positions on both surfaces of the sealing column 31, and sealing rings 34 are arranged in the inner cavities of the two installation grooves 33, the sealing performance between the sealing column 31 and the second sealing groove 24 and the first sealing groove 14 can be increased. Furthermore, the sealing performance between the second flange 21 and the first flange 11 can be improved, so as to ensure a tight fit with the flange and improve the sealing effect.
