Annular multi-specification wrench

Abstract

The invention discloses an annular multi-specification wrench. The annular multi-specification wrench comprises a wrench body. The wrench body comprises a work part and a handle. The work part is of a piece-shaped circular ring three-dimensional structure. Bayonets are formed in the inner circle of a circular ring and are regularly arranged in an annular manner. Each bayonet comprises two parallel main clamping faces and two auxiliary clamping faces connected with the two parallel main clamping faces. The included angle between every two adjacent clamping faces is 120 degrees. A hollow circular platform is connected to the position over the work part horizontally, and the work part is connected with the handle through the circular platform. The handle is parallel to the work part. By means of the manner, the annular multi-specification wrench is novel in structure, the bayonets of multiple specifications and types are annularly arranged on the work part, and the annular multi-specification wrench is comprehensive and convenient to use. Each bayonet is provided with four clamping faces, the bayonets can be better attached to needed bolts or nuts, and operation is easier. Meanwhile, the handle is arranged over the annular work part, the space is not limited, the hand can exert the acting force of the hand more easily, screwing is more convenient, and certain economic benefits and market prospects are achieved.

Description

technical field [0001] The invention relates to the field of fastening devices, in particular to an annular multi-standard wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with an opening or a sleeve hole for clamping a bolt or a nut at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction to twist the bolt or nut. Wrenches can be divided into two types: adjustable wrench and dead wrench. There are many kinds of dead wrench. The most common one in daily life is open-end wrench. Because of the two-end structure, the bayonet specifications that can be set on one wrench are limited, and a set of two-end wrenches is often required to meet the needs.
