[0002] A wrench is a tool used to turn bolts, nuts, and other objects that are difficult to turn by hand. This wrench includes a handle and a U-shaped opening at the end of the handle. One symmetrical side, the existing wrench includes adjustable wrench with adjustable wrench size and fixed wrench with fixed wrench size. It is very fast for loading and unloading bolts or nuts of the same type. The adjustable wrench is more convenient. The general wrench can only twist the fasteners with nuts. However, when some pipes do not have nuts and need to be tightened, pipe wrenches are needed. The repeated use of the two tools is inefficient. , so a wrench with convertible jaw angle is proposed

Abstract

The invention discloses a wrench capable of transforming a jaw angle. The wrench comprises a wrench body, a movable jaw, a too-shaped jaw, a limiting pin, a transforming wheel, a dowel pin and a fastening pin, wherein a mounting plate body is arranged above the wrench body; a wrench lip body is arranged on the tooth-shaped jaw; the movable jaw is mounted in the wrench body; the wrench lip body is matched with the movable jaw; a mounting part is arranged below the wrench lip body; the mounting part is fixedly arranged on the mounting plate body through the dowel pin; a locking surface is arranged on the mounting part; the locking surface is matched with the outer wall of the transforming wheel; the locking surface is connected with a convex blocking part; the transforming wheel is fixedly arranged on the mounting plate body through the fastening pin; a concave blocking part is arranged on the transforming wheel; a limiting slot is formed in the transforming wheel; the dowel pin acts on the limiting slot; and a handle is arranged below the wrench body. Jaw transforming is carried out through the transforming wheel, so that operation is simple; and the jaws are great in opening, so that cylinders of various shapes can be adapted, and therefore, scope of application is wider.
