Amplified hold-down clamp

摘要

The clamp is a locked over-center toggle clamp having a toggle lever that actuates a clamp arm between clamped and released positions. An amplification lever is secured to a cam pivot for rotation of the cam pivot inside a base. One end of the clamp arm is pivoted to the cam pivot to act as a follower so that rotation of the cam pivot cams the clamp arm to amplify the hold-down force of the toggle clamp.
