Patent ID: 7836968

Claim:
A power tool system comprising: a power tool comprising a motor, a start switch with ON and OFF states, wherein the OFF state comprises a state in which the start switch prevents the motor from running, and wherein the ON state comprises a state in which the start switch does not prevent the motor from running, a rotatable output drive, a drive train operatively extending between the motor and the output drive for transmitting torque from the motor to the output drive, and a tubular sleeve, a portion of the power tool extending through the tubular sleeve, the tubular sleeve being movable along an axis relative to the power tool and rotatable output drive between first and second positions, wherein the sleeve is biased toward its first position, wherein the tubular sleeve and start switch are operatively connected with each other such that the start switch is in its OFF state when the sleeve is in its first position, and the start switch is in its ON state when the sleeve is in its second position, and wherein axial movement of the tubular sleeve from its first to its second position places the start switch from its OFF state into its ON state.
