  • the disc may comprise a gear wheel included in a gear transmission driven from the input end.
  • a gear reduction and a suitable adaptation to the possibly limited torque of the power tool may thereby be obtained.
  • the mechanism is adapted to convert the rotational movement of the input end to a back and forth rotational movement of the output end.
  • the output end may then be adapted for drive engagement with the ac- tuatable shaft end by a direct drive engagement with the shaft end.
