ABSTRACT:
A mechanical clamping device for coupling any an object requiring infinite positioning to a fixed surface and which quickly and easily locks the object firmly in position without the use of electricity or hydraulic fluids. A triple pivoting linkage is employed which magnifies the force applied to a locking lever to thereby facilitate locking of the object in position. The ball seat configuration provides an additional force magnifier at the interface of the ball of the object being clamped and a ball seat defined within the clamping device. An adjusting screw is preferably provided for selectively varying the play between upper and lower clamping plates thereby enabling the clamping force applied to a ball within the device to be varied.
