Abstract
The present invention discloses a tapping shank which mainly consists of axial, radial and deflection comprehensive floating mechanisms and a high-sensitivity rolling clutch safety mechanism. The present invention has an actual safety guarantee in tapping an M1 thread, solves the problems of axial pressure and tension of a main shaft on a screw tap, and eccentric and deflection errors between the screw tap and a bottom hole, ensures the precision of a hole diameter and a longest service life of the screw tap, and is also a high-precision hole machining floating reamer shank.
