Apparatus for single hand attachment of drywall corner beads

Abstract

A tool that can be held and operated with one hand to attach a corner bead to an outside corner of drywall includes a substantially V-shaped member having a pair of interior surfaces disposed at an angle of less than 100° and a frame or handle attached thereto. The handle maybe sized and shaped to fit comfortably in the palm of a human hand. A lever is pivotally attached to the handle. A pair of opposed pincers having pointed tips are pivotally mounted relative to the V-shaped member so as to allow the tips to move in a converging direction. A mechanical linkage system translates force applied to the lever into a the converging motion of the pincers. The apparatus facilitates transmitting to the corner bead force applied to the frame in a first direction and deforming the corner bead with a second force applied to the frame/lever in a second direction, the second force having a component in a second direction substantially opposite the first direction, the second force having a magnitude correlating to the defamation force applied to the corner bead.
