Abstract
A hand-operated machine tool includes a movable lever having a cutting portion and a driving portion, a stroke drive comprising a rotating stroke eccentric driven about a rotation axis, the stroke drive operable with the driving portion to reciprocate the cutting portion between end positions, a cam carrier comprising an adjusting cam disposed between the stroke eccentric and the driving portion and operable to move together therewith, the adjusting cam comprising a pitched portion, and a retaining stop configured to engage the cam carrier and move between a released position and an active position. When the retaining stop is moved to the released position, the cam carrier engages and drives the stroke eccentric. When the retaining stop is moved to the active position, the cam carrier disengages the stroke eccentric, thereby adjusting the end positions of the movable lever.
