Fastener-driving tool including a reversion trigger

A fastener-driving tool comprising:

• a housing;
• a trigger movably connected to said housing, said trigger being movable between a rest position and an activated position;
• a control valve including an actuating pin;
• an actuation lever movably connected to said trigger, said actuation lever being movable between a rest position and an actuating position adjacent to said actuating pin;
• and
• a workpiece-contacting element movably connected to said housing and being movable between a rest position and an activated position, said workpiece-contacting element including a fixed portion and an end portion movably connected to said fixed portion and being movable between a first position and a second position,
• wherein in said first position, said fixed portion and said end portion are generally aligned with each other and said end portion is not configured to contact said actuation lever when said trigger is in said activated position and said workpiece-contacting element is moved to said activated position, and
• wherein in said second position, said end portion is at a designated angle relative to said fixed portion and is configured to contact said actuation lever when said trigger is in said activated position and said workpiece-contacting element is moved to said activated position;
• wherein in a powered mode, said end portion moves to said second position such that the tool is actuated each time said workpiece-contacting element contacts a workpiece and moves to said activated position causing said end portion to contact said actuation lever and said actuation lever to contact said actuating pin and initiate an actuation of the tool;
• and
• wherein in a non-powered mode, said end portion is in said first position such that the tool is actuated each time said workpiece-contacting element and said trigger are each respectively moved from said rest position to said activated position in a designated sequence.
