Abstract
A portable crimping tool is disclosed that includes an actuating mechanism that varies the amount of force made available to the crimping dies. A linear actuator having an axis is provided to move a movable die along that axis into crimping engagement with the mating die. The actuating mechanism includes a pair of links pivotally attached to a slide member. A wedge carried by the linear actuator engages a pair of rollers on the links, causing the rollers to move about other rollers attached to the frame, thereby causing the links to move the dies into crimping engagement.
