发明名称 Portable wire puller
摘要 An automatic wire puller is described for drawing an electrical wire from a remote location to a junction box. The puller includes a frame adapted to fit between support studs adjacent an electrical junction or service box. Adjustable brackets on a top side of the frame extend out to engage the studs on back side edges thereof, while similar brackets on the frame bottom engage the opposite, front sides of the studs. A powered winch drawn on the frame turns on an axis spaced forwardly of the frame. The winch produces a moment against the two sets of brackets, causing them to securely clamp against the studs as the winch line is taken up onto the drum.
