Abstract
A gripping device with a precision ratcheting mechanism includes an upper and a lower arm, each terminating in a U-shaped receiver, connected by a pair of pivotal joints. A pawl device is pivotally connected to the U-shaped receiver of the upper arm, while a post, passing through the pawl device, is pivotally connected to the lower arm. The post contains a plurality of teeth on one surface and a teeth-engaging member in the pawl device contains a plurality of corresponding teeth which engage the teeth on the post. The teeth are disengaged by pressing a release surface, which compresses a spring and physically moves the teeth-engaging structure away from the post, allowing the post to move freely within the pawl device.
