US Patent 6991202 Flex grip fixture clamp

A grip head includes a progressive support clamp, a biscuit clamp and a ball joint. The progressive support clamp can be actuated from an open position to a support member clamp position. The support member clamp position clamps a support member in a support member channel defined in the progressive support clamp and allows rotation of a ball of the ball joint, to enable positioning of an accessory coupled with the ball. The progressive support clamp can be further actuated to a full clamp position. The full clamp position clamps the support member and fixes the position of the ball and the position of the accessory coupled therewith.
