The invention discloses safety nail clippers which comprise a first clipper, a second clipper and a lever sheet. The first clipper is opposite to the second clipper, a lever mechanism which penetratesthe first clipper and the second clipper is arranged at one end of the lever sheet, a turnover clamping piece is arranged at the other end of the lever sheet, is close to the first clipper and can beturned over around a joint, which is used as a fulcrum, of the turnover clamping piece and the lever mechanism, a free end of the turnover clamping piece can be stretched to be lengthened, a connecting column is arranged at the other end of the first clipper and the other end of the second clipper, a safety positioning mechanism is arranged in the surface, which is close to the first clipper, ofthe connecting column and can be folded into a positioning hole in the free end of the turnover clamping piece, and the first clipper and the second clipper can be pulled by the turnover clamping piece by angles controlled by restraint inclination angles of the safety positioning mechanism. The safety nail clippers have the advantages that the safety nail clippers are provided with the safety positioning mechanism, and accordingly force exerting angles of the turnover clamping piece can be restrained; the same force exerting angles always can be maintained, accordingly, the safety nail clippers are high in safety in use procedures, and the safety of users can be enhanced.
