[0002] Adjustable angle steel pipe refers to a steel pipe that can adjust the angle of connection with other steel pipes or components in some way. According to different adjustment methods, this type of steel pipe can be divided into many types, such as steel pipes adjusted by wheel buckle assembly, steel pipes adjusted by threaded connection, and steel pipes adjusted by other special structures.

[0003] In the prior art, the connection between two pipes is usually fixed by a connecting assembly, and the angle of the two pipes is the same as the angle of the connecting assembly. For example, if the two pipes are connected by a connecting elbow, the connection stability is good. However, the connection angle of the two pipes is fixed, which is the bending angle of the connecting elbow. The angle between the two pipes is not convenient to adjust after the connection, which affects practicality. Therefore, a steel pipe with adjustable angle is designed to solve the above problem.
