ABSTRACT:
A toggle clamp includes a movable first pin having an axis and a stationary second pin. An arm is carried by the first pin for rotation in a first direction applying pressure to a load and a second direction releasing the pressure. An exterior spring element is coupled between the first and second pins. The spring element exerts a spring force that biases the first pin toward the second pin. The spring element is releasable for exchange with another spring element to change the spring force.
