Abstract
A power tool is provided and includes a housing having a first longitudinal axis extending therein. An output shaft is mounted in the housing along the longitudinal axis operably connected to the working element. A motor in the housing is provided for driving the output shaft. A transmission system has cooperating portions which are movable between (1) a first state wherein the cooperating portions are disengaged from each other allowing the output shaft to reciprocate, and (2) a second state wherein the cooperating portions are engaged with each other causing the output shaft to rotate. A wobble driver is mounted to the output shaft with the wobble driver having (1) a first mode wherein the wobble driver is in driving relation to the output shaft and is capable of reciprocating with the output shaft along the first longitudinal axis, and (2) a second mode when the wobble driver is in non-driving relation to the output shaft. An actuator cooperates with the wobble driver and one of the transmission system cooperating portions. The actuator is selectively movable between (1) a first position wherein the transmission cooperating portions are in their first disengaged state and the wo…
