[0028] The connecting mechanism 3 comprises a support column 31 fixedly connected to the outer wall of the inner spline 1, a rectangular plate 32 fixedly connected to the side of the support column 31 away from the inner spline 1, a support plate 33 fixedly connected to one side of the rectangular plate 32, a threaded rod 34 provided inside the support plate 33, an arc-shaped block 35 threadedly connected to the outer wall of the threaded rod 34, a support arm 36 fixedly connected to the outer side of the arc-shaped block 35, a connecting block 37 fixedly connected to one side of the support arm 36, and a clamping block 38 fixedly connected to the bottom of the connecting block 37.

[0029] Further, a rotating hole is formed in the support plate 33, and the threaded rod 34 is rotationally connected to the inner wall of the rotating hole, so as to stably support the threaded rod 34.

[0030] Further, the threaded rods 34 are oppositely threaded at the two ends of the outer wall, and a torsion sleeve is fixedly connected to the outer wall of the threaded rod 34, so as to facilitate the rotation of the threaded rod 34 by the torsion sleeve.

[0031] Further, a sliding hole is formed in the arc-shaped block 35, and the arc-shaped block 35 is slidingly connected to the outer side of the support column 31 through the sliding hole, so as to stably limit the movement of the arc-shaped block 35. Embodiment

[0032] Reference Figures 1 to 5 Further, based on the first embodiment, the sealing mechanism 4 comprises a sealing cover 41 movably connected to the outer side of the inner spline 1, a sealing ring 42 fixedly connected to the inner side of the sealing cover 41, and a sealing groove 43 formed in the outer side of the inner spline 1, so as to seal the connection between the inner spline 1 and the outer spline 2.

[0033] Further, the sealing ring 42 is movably connected to the inside of the sealing groove 43, and the outer spline 2 penetrates the sealing cover 41, so that the sealing ring 42 can be stably inserted into the inside of the sealing groove 43.

[0034] Further, a rectangular hole is formed in the inside of the sealing cover 41 and the top of the inner spline 1, and the clamping block 38 penetrates the rectangular hole, so that the clamping block 38 can move through the rectangular hole.
