Novel rotary joint

The invention provides a novel rotary joint with a simple structure and easy operation. The rotary joint comprises a sphere (1) and a main body (2), wherein a connecting passage (3) is arranged in the sphere (1) and the main body (2), the sphere (1) is provided with a spherical joint (7), an outlet of the connecting passage (3) is arranged at the end part of the spherical joint (7), a sphere holding cavity (8) distributed in a spherical surface shape is arranged in the main body (2), and the sphere (1) is arranged in the sphere holding cavity (8); the sphere (1) provided by the invention is provided with the spherical joint (7), and the sphere can very freely rotate in the holding cavity by the characteristics of the spherical structure when the spherical joint (7) is arranged in the sphere holding cavity (8), so that the rotary joint can fit for pipeline connections of a plurality of steering angles, thereby reducing the purchase amount of the joint, and the purchase cost is reduced as a result.
