[0029] In this embodiment, when fixation is required, since the sealing sleeve 5 is threadedly connected to the protruding sleeve 2, the fixing sleeve 3 will be limited accordingly, and then the external tube 101 is inserted into the fixing sleeve 3, and the sealing tube 6 is inserted into the sealing sleeve 5, so that the flexible ring 7 is in contact with the sealing ring 8, and then an outward thrust is applied by the push spring 10 to pull the sealing tube 6 outward, thereby ensuring the effective sealing of the sealing ring 8 and the flexible ring 7, and then fixed by multiple bidirectional rods 11, thereby ensuring the installation and sealing effect.

[0030] See also Figures 2 to 5 As an implementation method of the clamping mechanism: the clamping mechanism includes a two-way rod 11, a plurality of telescopic holes 12 are provided on the side wall of the fixed sleeve 3, and a two-way rod 11 is slidably connected in each telescopic hole 12, a spiral groove 13 is provided on the side wall of the external pipe 101, and a plurality of two-way rods 11 respectively abut against the spiral groove 13, and each two-way rod 11 is provided with a limiting sleeve 14, and the limiting sleeve 14 abuts against the outer wall of the fixed sleeve 3.

When stable fixation is required, continue to rotate the threaded sleeve 15 so that the multiple bidirectional rods 11 respectively pass over the rubber strips 17, and then make the multiple bidirectional rods 11 abut against the fixing sleeve 3 respectively. Since the fixing groove 18 has no elasticity, the bidirectional rod 11 is fixed, and then the external tube 101 and the fixing sleeve 3 are in a stable fixed state, thereby completing the fixing process.
