Abstract
This invention relates to an open-end wrench structure, including a body that has a handle portion and a first rotation portion. The first rotation portion is disposed with a first layer, a second layer and a third layer. The second layer is protruded outside the first layer at the top and bottom sides. The second layer is surroundingly disposed to an opening end of the first rotation portion. The cross sectional area of the second layer is smaller than that of the first layer. The second layer is away from the handle portion and the third layer connects the first layer and the second layer. The first layer is provided with a fourth layer at an extension to the handle portion. The second layer is provided with a fifth layer at an extension to the handle portion. The third layer is provided with a sixth layer at an extension to the handle portion. The first layer is provided with a first cross section. The second layer is provided with a second cross section. The cross-sectional area of the second cross section is smaller than that of the first cross section. A third layer is disposed between the first cross section and the second cross section in a stacked and stretched manner, which means that the first cross section becomes the second cross section gradually. The fourth section has a third cross section. The fifth layer has a fourth cross section. The cross-sectional area of the fourth cross section is smaller than that of the third cross section. A sixth layer is disposed between the third cross section and the fourth cross section in a stacked and stretched manner.
