Abstract
An electro-magnetic stapling tool having a mechanism for adjusting the power with which the solenoid-operated plunger and the staple driver drive the staples. In its preferred embodiment, the power adjusting a mechanism includes a manually adjustable selector knob having a cam element, and includes a cam follower mounted in association with the upper end of the solenoid core. Rotation of the selector knob adjusts the length of the solenoid power stroke and the resulting driving power of the stapling tool.
