The invention relates to a novel lifting ring for a finished product prestressing steel strand. The novel lifting ring comprises a lifting ring body and an inner hexagon connecting bolt, wherein the connecting bolt is coaxially arranged on the lower end part of the lifting ring through penetrating through a gap; a boss is coaxially arranged on the lower end part of the lifting ring body; a gasket is arranged between the upper end face of the boss and a screw cap of the connecting bolt; a backing ring is arranged in an annular groove formed on the bottom part of the lifting ring body; the lifting ring body is provided with a detachable wrench component. The lifting ring body of the lifting ring can rotate at 360 degrees around an axis, so that the phenomenon that the steel strand moves along with the lifting ring is avoided, and the working efficiency is effectively improved; after the steel strand penetrates through a corrugated pipe, the connecting bolt can be taken out, so that reutilization is realized, and the construction cost is effectively reduced. The novel lifting ring is simple in structure, scientific and reasonable in design, and convenient and quick to operate, not only is the construction efficiency improved, but also the reutilization is realized, and the cost is effectively reduced.
