Abstract:
1. A vibrating drill/driver comprising: a tool housing; a spindle disposed within said tool housing movable in an axial direction thereof and also rotatable about a longitudinal axis thereof; a motor disposed within said tool housing for driving said spindle about the longitudinal axis thereof; a switching handle supported by said tool housing for rotation about a longitudinal axis thereof; a clutch mechanism interposed between said motor and said spindle for adjustably varying a working torque in dependence on rotation of said switching handle; a switching ring having a recessed portion defined therein and capable of rotating together with said switching handle; a switching plate having a tip for engagement in said recessed portion; and a vibrating cam mechanism operable to undergo a slidable engagement to provide a vibration for repeatedly driving the spindle in an axial direction thereof when said tip of said switching plate is engaged in said recessed portion of said switching ring, wherein the rotation of said switching handle in one direction causes the vibrating drill/driver to be set in one of a clutch mode in which a working torque can be varied, a vibrating mode in which the spindle is provided with a vibration in an axial direction thereof, and a drilling mode in which a working torque from said motor is directly transmitted to said spindle in this order.
