Design of main parts of spring collet

Collet sleeve The clamping organization of the spring collet selects the spiral clamping organization to finish clamping and lock the tool handle. The nut sleeve is equipped with a gear ring, which is intended to transmit torque through the correct meshing of the gear ring and the gear in the clamping organization. In order to reduce the collision and loss of the ring gear nut sleeve when clamping the tool, a V-shaped groove is added between the outer end of the ring gear nut sleeve an
