The invention relates to a straight-back lifting hook with a buckle type safety piece. The straight-back lifting hook with the buckle type safety piece comprises a lifting hook body and a safety piece, wherein the safety piece is arranged at an opening part of the lifting hook body; one end of the safety piece is configured to be a fixed end and is connected with the upper end of the lifting hook body; the other end of the safety piece is configured to be a connection end; an opened pin groove is formed in the end and is connected with a locking pin which is arranged at the lower end of the lifting hook body in a clamping manner, so that the safety piece is connected with the lifting hook body in a releasable locking mode; a sealed rectangular pin groove is formed in the fixed end of the safety piece; a rotation shaft fixedly connected with the upper end of the lifting hook body is arranged in the rectangular pin groove; two opposite support pieces are respectively arranged at the upper end and the lower end of the lifting hook body; a rotation shaft is arranged between the support pieces at the upper end; and a locking pin is arranged between the support pieces at the lower end. Compared with the prior art, the straight-back lifting hook can be welded in any position of the workpiece; and the lifting hook adopts the buckle type safety piece, so that the bearing strength is high, and thus a steel cable of the lifting hook cannot fall off. The straight-back lifting hook is convenient to use, safe and reliable.
