The invention relates to the technical field of space robots, in particular to a three-degree-of-freedom soft butt joint which comprises a transmission mechanism, a damping buffering assembly and a sensing assembly. The transmission mechanism comprises a clutch, a cross shaft structure, a Z-axis rotating shell, a Y-axis rotating shell and the like; the damping buffer assembly comprises a rotary magnetorheological damper, a torsion spring mechanism and the like; the sensing assembly comprises an encoder and the like. According to the soft butt joint, the flexibility of a butt joint mechanism is controlled mainly through a damping buffering assembly, space six-dimensional momentum unloading is achieved according to an operation task, and therefore soft butt joint of space operation is achieved.
