Zusammenfassung:The invention relates to an anti-rotation feeding tool used for drilling engineering in an petroleum and natural gas industry, and solves the problems of stick-slip phenomena of drill columns in drilling engineering, inabilities of tool surfaces to stabilize during borehole deflecting, de-pressing of drill bits and the like. According to the technical scheme, an inner cavity of the lower portion of an upper joint is arranged as an internal spline, an external spline of the upper end of a mandrel is inserted into the internal spline of the upper joint, the upper end of the upper joint is in screwed connection with an upper drill column, and the lower portion of the upper joint is in screwed connection with an upper sleeve; a protruding outer edge of the lower end of the upper sleeve and a protruding outer edge of the upper end of a lower sleeve are hooked with each other; T-shaped hooks at the upper ends of the three slips are installed in three T-shaped recesses in the lower ends of slip bases respectively, a
