Abstract
A stapler has a base section and a stapling unit. The stapling unit is pivotally attached to the base section, and the base section is pivotally attached to a baseplate. In an initial position, the base section is fixed relative to the baseplate through a releasable locking mechanism connected to the baseplate and the base section. The base section has pivoting bending arms in an area underneath a support surface for a workpiece to be stapled. When a driver has driven a staple into the workpiece to a position in which the crown of the staple is in contact with the workpiece, the locking mechanism is released, and the base section pivots and is tilted against the baseplate, causing the bending arms to pivot so that the legs of the staple are bent into a position against the workpiece. A cutting pad disposed in an area between the bending arms interacts with the bending arms to cut off excess length of the staple legs.
