Description

Open end wrench structure

The invention relates to an open-end wrench structure, in particular to an open-end wrench structure, the first rotating part is provided with a first layer and a second layer, and the surface and opening of the second layer are provided. The other surfaces of the wrench are treated differently.

As is known in the prior art, a conventional open-end wrench structure, such as U.S. Patent No. 2,687,056, is based on the fact that one or both ends of the body are provided with a drive portion which is a domed open end, the body and drive The part is a forged type, and the open-end wrench is subjected to a plurality of other processes, such as annealing, drum, punching, heat treatment or vibration processing, to complete an open-end wrench structure, and the open-end wrench is applied after the process is completed or during the process step. Matte treatment, mirror treatment, electroplating, blackening, nickel plating, chrome plating, tin plating, titanium plating, color electric painting, painting, coloring, printing, transfer or other methods are applied to the entire surface of the body and the driving part. The treatment makes the open-end wrench have a more aesthetic appearance, which is also the basic structure of a conventional open-end wrench.

The matte finish, mirror finish or electroplating allows the open-end wrench to have its own metallic color, while black, nickel, chrome, tin, titanium, color, lacquer, color, print or transfer The outer surface of the wrench has a color representation.

However, the missing structure of the U.S. patent structure is that all surfaces of the body and the driving portion have a single surface shape, such as a matte surface, a mirror surface, a plated surface or a blackened surface, and the open wrench is in a single state. Underneath, the open end wrench is still monotonous in appearance.

In view of the structure of the above-mentioned conventional open-end wrench tool, the inventors have years of experience in related industries, and finally have an open-end wrench structure product.

The system of the open-end wrench structure is provided with a first rotating portion, the first rotating portion is provided with a first layer and a second layer, and the outer surface of the second layer is differently processed from other outer surfaces of the open-end wrench deal with.

An open-end wrench structure includes: a system having a handle, the handle having a first rotating portion at one end, the first rotating portion being an open end, the first rotating portion being provided a first layer and a second layer, the first layer is U-shaped, the first layer is connected to the handle, the second layer is protruded from the upper and lower sides of the first layer, and the second layer is wound around The open end of the first rotating portion, the sectional area of the second layer is smaller than the sectional area of the first layer, and the second layer is away from the handle; the open wrench is applied to the body and the handle after the process is completed or in the process step And the first surface of the first rotating portion is subjected to a first processing, the second layer is provided with a first surface and a second surface, and the first surface and the second surface are removed by the machine equipment, the first surface and the second surface The second processing is further performed, and the second processing is different from the first processing.

The first surface and the second surface are the second processing, while the other is the first processing, and the second processing is different from the first processing, such that the first rotating portion has two different State appearance, the appearance of the open-end wrench is variability. The first rotating part of the open-end wrench has different structures. If each open-end wrench has the same first processing, but the different first rotating parts are treated differently, the second processing is performed by the appearance.
