Abstract

The mechanical wrench includes a first jaw, A, interacting with a second jaw, B. The jaws are operated by a tension handle having a rounded end with a hole in it, and a mini roller which engages with a tapered wedge. When mounted on a pivot axis on the first jaw, the handle can apply pressure to the second jaw via the roller and tapered wedge. The first jaw has a square housing enclosure in which a shaft of the second jaw can slide freely. The movement of the tension handle up and down controls the release or pressure of the second jaw with respect to the first jaw.

Description

DESCRIPTION
TENSION WRENCH
My invention comprises of a wrench with two jaws. Jaw A & B, Jaw A holds the main mechanism. With a tension handle that "varies" tension. By way of moving backwards and forwards on an axis. Located on the side of Jaw A's body. Jaw B slides up & down within Jaw A's bodywork.
When the given width of both jaws has been decided, the tension handle is pulled down. Which turns a "concentric" head at the top end of the handle. An inbuilt "mini" roller within the "concentric" head. Engages with an independent tapered wedge, vertically aligned with the moving shaft of Jaw B. Hence the greater the pressure of the handle, engaging the roller on the concentric head of the handle. Further toward the tapered wedge. The greater the grip will be on Jaw B. ai -Jaw a au -Jaw a side view b-Jawb c -tension handle d -tapered wedge e -roller on tension handle f -hole for tension handle to pivot on g -return spring
