摘要： A screwdriving including a housing with a handle section and a motor housing section. A longitudinal axis of the handle section is at an offset angle with respect to a longitudinal axis of the motor housing section. A motor is housed in the motor housing section. An output tool holder is selectively driven by the motor. A user actuatable trigger activates the motor. The screwdriver further includes a bit holder rotatably held on the housing, the bit holder including a first section which includes a plurality of bit retainers; and a second section including a plurality of detents. The screwdriver further includes a pin which engages with the plurality of detents to hold the bit holder in one of a plurality of rotational positions.

摘要： A chainsaw which has a low profile chain cover and a chain bar tightening clutch system. The chain bar tightening clutch system can have a bar tightening knob which drives a clutch which governs the amount of pressure applied to the chain bar by operating the bar tightening knob. The chainsaw can have a chain bar tensioning system which can have a tensioning drive member in an offset position from the tensioning post which positions the tensioning post to achieve a chain tension and compact chainsaw design. The chainsaw can also have an oil cap with a lock channel having a detent with produces a sound when moved from a disengaged to an engage position with an oil reservoir.

摘要： A power tool system which includes a first base unit and a second base unit. The first and second base units each include a housing, a motor housed in the housing, a coupler which is operatively connected to and selectively drivable by the motor and a trigger for activating the motor to drive the coupler. The system also includes a first attachment head which is removably couplable with both the first base unit and the second base unit so that it can be driven by the respective motor of the base unit to which it is attached and a second attachment head which is removably couplable to the first base unit, but which is not couplable with the second base unit.
