The outer wall of the wear-resistant pad 3 fits the outer wall of the seamless high-pressure pipe body 1. The connecting block 501 is fixedly connected to the rear outer wall of the wrapping block 2. The rear outer wall of the wrapping block 2 is provided with a first positioning hole 6, and the front end of the positioning key 503 is adapted to the first positioning hole 6. The rear outer wall of the adjusting column 4 is provided with a second positioning hole 7, and the front end of the positioning key 503 is adapted to the second positioning hole 7.

[0025] See also Figure 1-Figure 3 The utility model provides a technical solution: the seamless high-pressure pipe body 1 can rotate inside the wrapping block 2 to adjust the inclination angle of the seamless high-pressure pipe body 1, and the wear-resistant pad 3 can prevent the friction and wear between the seamless high-pressure pipe body 1 and the wrapping block 2 during rotation inside the wrapping block 2, thereby protecting the outer wall of the seamless high-pressure pipe body 1;

[0026] By toggling the toggle key 504 backward, the positioning key 503 moves backward, the return spring 502 is compressed, and the wrapping block 2 can slide up and down on the outer wall of the adjusting column 4. When the wrapping block 2 moves up and down to a suitable height position, the toggle key 504 is released, and the positioning key 503 is reset forward with the rebound of the return spring 502. The front end of the positioning key 503 enters the first positioning hole 6 inside the wrapping block 2 and the second positioning hole 7 inside the adjusting column 4 in turn, thereby realizing the adjustment of the height of the wrapping block 2 and the seamless high-pressure pipe fitting body 1, which is convenient for height adjustment according to the actual docking situation of the seamless high-pressure pipe fitting body 1, increases the accuracy of docking, and reduces the installation risk of manual pipe holding.

[0027] Embodiment 2

[0028] A stable base 8 is fixed to the bottom outer wall of the adjusting column 4, and the top outer wall height of the stable base 8 is lower than the bottom outer wall height of the seamless high-pressure pipe fitting body 1.
