Fixing device for robot maintenance

The invention relates to the technical field of robot maintenance equipment, in particular to a fixing device for robot maintenance. The fixing device comprises a limiting structure, an angle adjusting structure, a length adjusting structure, a storage structure and staggering structures. The two staggering structures are symmetrically arranged diagonally at two ends of length adjusting structurefor adjusting the supporting length, the length adjusting structure is arranged to support two power arms different in separating distance conveniently, so that it is more convenient and flexible to operate, the staggering structures are arranged to support the two power arms not in the same plane conveniently, so that the power arms of various types are supported and limited, and the two staggering structures are symmetrically arranged diagonally, so that the staggering distance is increased. On end of the angle adjusting structure is connected to the staggering structures, and the limiting structure is arranged at t
