The invention discloses a single-degree-of-freedom rotary joint driven by synchronous ropes, and relates to the technical field of snake-shaped arm robots. In order to solve the problems that when an existing rope-driven single-degree-of-freedom rotary joint rotates, due to the fact that the rope variation of two driving ropes is different, when a single motor is used for synchronously controlling the two driving ropes, the two driving ropes cannot always keep constant tension without the assistance of other driving rope tensioning mechanisms, and the two driving ropes cannot be continuously tensioned. And therefore, the problems of poor joint rigidity and low motion precision are solved. The joint fixed section is rotationally connected with the joint movable section through two synchronous mechanisms, the top end of the joint movable section is connected with the bottom end of the joint connecting rod through a bolt, a plurality of first through holes are formed in the edge of the lower surface of the joint
