Fastener driving tool having contact arm in contact with workpiece

ActiveUS20050001001A1Sufficient operabilitySufficient workabilityStapling toolsNailing toolsEngineeringAbutment
A nail gun having a contact arm normally biased in a direction away from a workpiece by compression springs. A free end of the contact arm is brought into abutment with a workpiece and a trigger is pulled for driving a nail thereinto. In the trigger pulling operation, an inner end of the contact arm is engaged with a trigger arm which is biased by a plunger spring through a plunger. Because the contact arm is held on the workpiece, the plunger is moved to provide ON state against biasing force of the plunger spring. Immediately after the nail driving, a nail gun body is moved in a direction away from the workpiece relative to the contact arm. This causes disengagement of the trigger arm from the inner end, to relatively move the nail gun body toward the workpiece by the biasing force of the compression springs. This means relative movement of the contact arm in the direction away from the workpiece. If the trigger is released, the trigger arm is again brought into engagement with the inner end, because the trigger arm is normally urged toward the inner end by a trigger arm spring.
