The invention discloses a two-degree-of-freedom joint of a space robot. The two-degree-of-freedom joint comprises two joint driving assemblies and a joint transmission assembly. Two-degree-of-freedom movement of the joint can be achieved. Three movement modes of pitching, rotating and combining of pitching and rotating can be achieved by adjusting the rotating speeds and the rotating angles of two motors. The joint transmission assembly is a differential movement mechanism formed by two input bevel gears and an output bevel gear. The two input bevel gears are fixedly connected with corresponding hypoid gears respectively, and an output flange is fixedly connected with the output bevel gear.
