Abstract
An electromagnetic stapler includes a driver for driving fasteners into a workpiece, and a solenoid for providing power to the driver. The solenoid has a coil, and a core that is operatively connected to the driver. The stapler also includes a manually adjustable depth adjuster for adjusting a depth of drive of the fasteners. The depth adjuster is movable between a plurality of predefined positions, including a maximum depth of drive position, a minimum depth of drive position, and at least one intermediate depth of drive position. The depth adjuster includes a cam having a cam surface that interacts with the core so as to define an upper position of the core, an adjustment knob operatively connected to the cam, and a detent mechanism for securing the cam at one of the plurality of predefined positions to thereby define the upper position of the core.
