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. When mounted on a pivot axis on the first jaw, the handle can apply thrust to a shaft of the second jaw. The first jaw has a square housing enclosure in which the 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

tension wrench 1
Description:
The enclosed invention shows a mechanical wrench. It has two jaws. One Jaw A' is the principle foundation, the second Jaw B', interacts with Jaw A'. The second Jaw B, is enclosed with Jaw A by way of a square shaft, part of Jaw B. Jaw A has a square hole as part of its structure of which Jaw B' slides freely up and down.
Thirdly Jaw A has a handle attached to it which swings up and down on a pivot. The top part of the handle, nearest axis the pivot and attachment point has a concentric' rounded head so as to apply thrust' to the shaft of Jaw B. The handle when pulled downwards pulls Jaw A towards Jaw B as the handle when pulled, pushes the shaft of Jaw B and also pulls Jaw A toward each other similtaneously. C') L()
