Abstract

A stapler has a drive train that drives a stapling head toward a base part in a driving stroke and away from the base part in a return stroke. To accommodate thick workpieces to be stapled, without jamming, the drive train includes a coupling constructed so that its effective connection between coupled parts is releasable and so that it loses its effective connection during the driving stroke to prevent jamming.
