Abstract
Apparatus and method for biasing the handles of a plier-type tool. The tool includes a pair of pivotally connected members, each member having a handle portion and a jaw portion joined together by an interconnecting portion. The interconnecting portions define pivot structure by which the members are rotatably connected and structure for capturing a coil spring that is operative to urge the handles apart. When embodied in an internal retaining plier, the handles are urged towards an equilibrium position. The spring capturing structure in each region comprises a slot defined by a pair of nonconverging arcuate edges joined at one end by a rectilinear edge forming a spring abutment and a spring seat at the other end including a spring retaining tongue. The tongue is disposed in a plane diverging from the plane of the interconnecting region and extends inwardly such that when the handles are squeezed, the tongues of respective interconnecting region abut to provide a mechanical stop defining the maximum squeezed position of the handles.
