[0023] The above solution is adopted: by providing the adjustment mechanism 8, it is convenient for the staff to operate and use the limiting ring 5 when installing and adjusting the limiting ring 5.

[0024] refer to Figure 3 The positioning mechanism 9 includes a cross bar 901, a positioning rod 902 and a tension spring 903. The surface of the connecting block 803 contacts the surface of the cross bar 901. The rear side of the cross bar 901 is fixedly connected to the front side of the tension spring 903. The rear side of the tension spring 903 is fixedly connected to the inner wall of the positioning cavity 7. The tension spring 903 is sleeved on the surface of the positioning rod 902.

During rotation, the surface of the fixed column 802 is squeezed by the inner wall of the limit groove 13 to make the two fixed columns 802 move toward the opposite side, and the fixed column 802 drives the connecting block 803 to move toward the opposite side, and the surface of the cross bar 901 is squeezed by the surface of the connecting block 803 to move the cross bar 901 forward. The cross bar 901 drives the positioning rod 902 to move forward according to the moving trajectory provided by the limiting groove 11, and at the same time stretches the tension spring 903 to move the positioning rod 902 to the inside of the positioning cavity 7. At this time, the limiting ring 5 can be replaced. By replacing limiting rings 5 ​​of different calibers, connecting pipes of different sizes can be restricted to prevent displacement during use.
