A fastener guide mechanism in a fastener driving tool includes a door member for closing an opening formed on one of the lateral sides of a fastener guide having a driver guide and a fastener guide. The fastener guide includes therein a fastener guide channel. A fastener feeding device having a fastener feeding member moves the fasteners connected by a carrier and disposed in the fastener guide channel forwardly toward the driver guide track of the driver guide one after another. A pressing member is mounted on the door member for pressing the connected fasteners on the fastener feeding member. The pressing member is operable to contact the connected fasteners at a first position when the connected fasteners are of a first kind. The pressing member is operable to contact the connected fasteners at a second position separated from the first position in a direction away from the fastener guide channel. The pressing member is biased by a biasing member for normally biasing toward the connected fasteners. A stopper member prevents movement of the pressing member from the first position in a direction away from the fastener guide channel.

Electric screw driver

A depth adjusting device for a screwdriver which is adapted to control within predetermined desired limits the depth to which a fastener may be driven into a work. The depth adjusting device comprises a locking ring retentively engaging the tool housing, and an adjusting sleeve axially movably carried by the locking ring. The locking ring has a spiral ridge formed on the inner periphery thereof, and the adjusting sleeve has a spiral groove formed peripherally about the rear portion thereof and engageable with the spiral ridge of the locking ring. The locking ring also has an axial slit formed therein and a pair of lugs formed across the slit. A thumb screw is provided to tighten the lugs and thence to retain the locking ring on the adjusting sleeve.

Depth adjusting device for screwdrivers

A portable electric router conventional in its overall structure is disclosed which includes a locking system comprising a locking pin located in the motor housing and adapted to move in a direction perpendicular to and into locking engagement with the guide bar, and a locking lever pivotally disposed adjacent a grip of the motor housing and operative to axially move the locking pin. The locking lever is adapted to pivot toward the grip to thereby press the locking pin against the guide bar.
