Docking seat 31, the upper end surface of the first docking seat 31 is provided with a first docking block 33, a first fixed seat 34 is provided above the first docking seat 31, a first rotating seat 35 is rotatably provided above the first fixed seat 34, a second docking block 36 is provided on the upper end surface of the first rotating seat 35, a second fixed seat 37 is provided above the second rotating seat 38, a second rotating seat 38 is rotatably provided above the second fixed seat 37, and a second docking seat 39 is provided above the second rotating seat 38. This design solves the problem that the original prestressed concrete pipe oblique pipe has poor strength and is not convenient to adjust.

[0020] As the first embodiment of the present utility model: a first flange 32 is welded on the outer side of the first docking seat 31, and the first docking seat 31 is fixedly connected to the first mounting tube 1 through the first flange 32, and a second flange 311 is welded on the outer side of the second docking seat 39, and the second docking seat 39 is fixedly connected to the second mounting tube 2 through the second flange 311. This design facilitates the connection of the first docking seat 31 and the second docking seat 39 to the first mounting tube 1 and the second mounting tube 2 respectively. A rotation cavity 342 is provided on the upper end surface of the first fixed seat 34, and a rotation limiting ring 351 is provided on the lower end surface of the first rotating seat 35. The rotation limiting ring 351 rotates closely along the inner wall of the rotation cavity 342. This design allows the first rotating seat 35 to rotate freely relative to the first fixed seat 34. Thereby changing the tilt direction of the first rotating seat 35, a first docking groove 343 is provided on the lower end surface of the first fixed seat 34, and the first docking block 33 and the first docking groove 343 are engaged with each other. This design facilitates the fixed docking of the first fixed seat 34 and the first docking block 33. A first limiting hole 341 is provided on the outer side surface of the first fixed seat 34, and a first through hole 331 is provided on the surface of the first docking block 33.

A set of first rotating seat 35 can tilt the connection angle by 10 degrees. For example, when it is required to tilt by 20 degrees, the first rotating seat 35 and the second rotating seat 38 are selected for use together. When in use, the first docking seat 31 is first connected to the first mounting pipe 1 through the first flange 32, and then the first fixed seat 34 is clamped with the first docking block 33 through the first docking groove 343, and the limiting bolt is passed through the first through hole 331 and the first limiting hole 341. The first rotating seat 3 5 can rotate freely relative to the first fixed base 34 and change the tilt angle by 10°. Then, the second fixed base 37 is installed on the upper end of the first rotating base 35 in the same way. The second rotating base 38 can rotate freely relative to the second fixed base 37 and change the tilt angle by 10° again. Finally, the second rotating base 38 is fixedly connected to the second docking base 39 to complete the installation. Through the cooperation between the first rotating base 35 and the second rotating base 38, the angle change between 0-20° can be achieved. Similarly, the user can select more first rotating bases 35 and second rotating bases 38 for docking, thereby obtaining a wider range of angle adjustment.
