Abstract:
A reciprocating cutting tool, comprising:a motor generating a rotational output that is utilized to drive a blade in an orbital path with respect to a workpiece, a motion conversion mechanism coupled to the motor, a slider coupled to or incorporated within the motion conversion mechanism, wherein the slider linearly reciprocates within a first plane when the motor is driven, but substantially does not move in a second plane that is substantially perpendicular to the first plane and a blade holder shaft, a means for pivotally coupling said blade holder shaft to the slider, wherein the blade holder shaft can reciprocate in the first plane and wherein said means allows said blade holder shaft to reciprocate in the second plane, the second plane corresponds to a plane for cutting the workpiece, and whereby orbital cutting motion of the blade in the second plane is generated during a cutting operation.
