The utility model relates to the field of torsion sensors, in particular to a static torsion sensor with an overload protection structure, which comprises a torsion sensor ring, a torsion disc, a connecting block, a strain gauge, an overload limiting block and an overload bump. The torsion disc is located in the torsion sensor ring, and the connecting block is connected between the torsion disc and the torsion sensor ring; an overload limiting block is fixed on the torsion disc, and an overload limiting groove is formed in one side, facing the torsion sensor ring, of the overload limiting block; an overload protruding block is fixed to the inner wall of the torsion sensor ring and inserted into the overload limiting groove, and an overload protection wire groove is formed between the overload protruding block and the inner wall of the overload limiting groove. The overload protection wire groove is formed between the overload protruding block and the inner wall of the overload limiting groove, when overload o
