[0027] refer to Figure 2 , Figure 3 , Figure 4 The longitudinal fixing assembly 6 includes a shell 1 61 and a shell 2 62. The shell 1 61 and the shell 2 62 are both semicircular. The bottom of the shell 1 61 and the shell 2 62 are rotatably connected by a rotating shaft 63. The top of the outer surface of the shell 1 61 is fixedly connected with two ear plates 64. The outer sides of the two ear plates 64 are rotatably connected with a pulling plate 65. The inner side of the pulling plate 65 is located at the rear end of the ear plate 64 and is rotatably connected with a rotating rod 66. The middle part of the rotating rod 66 is threadedly connected with a fixing rod 67. The end of the fixing rod 67 is threadedly connected with a resisting rod 68. The top of the outer surface of the shell 2 62 is fixedly connected with two fixing plates 69. The fixing plate 69 is engaged with the resisting rod 68. By rotating the pulling plate 65, the rotating rod 66 is rotated, and then the fixing rod 67 threadedly connected with the rotating rod 66 is synchronously lifted or lowered, and then the resisting rod 68 is also synchronously rotated in the fixing plate 69 with the movement of the fixing rod 67, thereby realizing the function of clamping or loosening between the shell 1 61 and the shell 2 62.

[0028] Reference Figure 3 , Figure 4 The longitudinal fixing component 6 also includes a sealing rubber strip 610 on the inner wall surface of the shell 1 61 and the shell 2 62. A snap-fit ​​groove 611 is provided between the sealing rubber strips 610. The width of the snap-fit ​​groove 611 matches the width of the snap-fit ​​plate 52. When the shell 1 61 and the shell 2 62 are used to fasten, the snap-fit ​​plate 52 is placed in the snap-fit ​​groove 611.

At the same time, the clamping plate 52, under the extrusion of the shell 1 61 and the shell 2 62, will gradually reduce the gap between the first flange 1 and the second flange 2 along the wedge surface, thereby greatly improving the fit tightness between the first flange 1 and the second flange 2. At the same time, the sealing rubber strip 610 can further enhance the overall sealing effect.
