An upper clamping member detachably connected to a lower support mechanism by a threaded member positioned in line with the shear bar axis to clamp the shear bar therebetween connecting apparatus detachably affixing the shear bar to each of the levers includes a threaded fastener received through an opening extending through each lever and threadably engaged with the shear bar. The connecting apparatus also includes cupped washer assemblies to create a ball joint effect to facilitate the relative movement between the levers and the corresponding fasteners, permitting the shear bar to be moved linearly by a pair of pivotally movable levers.
