Description

Open end wrench structure

The invention relates to an open-end wrench structure, in particular to a first rotating part of the open-end wrench structure, which is provided with a first layer, a second layer and a third layer of the laminated stretch, so that the open-end wrench structure of the invention is achieved The material is saved without reducing the use of the rotating torque and has a balanced design structure.

As is known to us, the conventional open-end wrench structure, as shown in the seventeenth figure, is based on a second body 60 having a second handle 61 and a second body 60 thereon. The surface of the second rotating portion 62 is flat, the second rotating portion 62 is provided with a larger thickness relative to the second handle portion 61, and the second rotating portion 62 is open. The end is rotated by the fitting screw.

However, the second structure of the second body 60 is missing in that the second rotating portion 62 has a large thickness and can have a large torque mainly when the screwing member is rotated, but the second body 10 also has a large weight. It takes more effort to spin and create a lack of wasted material.

Another open-end wrench structure, please refer to FIG. 18, which is further characterized by a third body 70 having a third handle 71 and a third rotating portion 72. The first rotating layer 72 is provided with a first layer 721 and a second layer 722. The first layer 721 and the third handle 71 have the same thickness, and the second layer 722 is wound around the third spiral. At the open end of the movable portion 72, the second layer 722 protrudes from above and below the first layer 721, that is, the thickness of the second layer 722 is large. In the thickness of the first layer 721, the structure of the third body 70 is generally known in the industry as the German standard model DIN 3113.

However, the missing structure of the third body 70 is:

The first rotating portion 72 is provided with a first layer 721 and a second layer 722. Although the third rotating portion 72 has the advantage of saving material and reducing the overall open-end wrench compared to the second rotating portion 62, However, the third rotating portion 72 reduces the partial volume compared to the second rotating portion 62. Therefore, the user does not easily obtain a better rotational torque when the third body 70 is rotated, which is the third rotation. The structure of the moving portion 72 is missing.

The conventional open end wrench has two basic structures: a second rotating portion 62 and a third rotating portion 72. The second rotating portion 62 has a missing material, and the third rotating portion 72 is opposite to the second rotating portion. Although the portion 62 has the advantage of reducing the volume and reducing the material, the torque of the second rotating portion 62 is reduced, and the two types of open-end wrench structures have relative advantages and relative lacks.

In view of the above-mentioned lack of the conventional open-end wrench structure, the inventors have been engaged in the manufacturing and design experience of related industries for many years, and finally have a product that can solve the drawbacks of the open-end wrench structure.

Customized open-end wrench structure for weight and torsion The invention is not related to the design of an open-end wrench, and the first rotating part of the open-end wrench structure is provided with a first layer, a second layer and a third layer of the laminated stretch. The open-end wrench structure of the present invention has a balanced design structure by achieving material saving without reducing the use efficiency of the rotating torque.

The solid surface is pulled by the first layer and the second layer.

a stack between the first section and the second section The third layer is stretched to reduce the weight of the first rotating portion, but has a better rotational torque, and the first rotating portion is structurally balanced between the weight and the rotational torque. The third layer of the first rotating portion has a toughness when the first rotating portion is about half of the state of the screwing member, and the third layer is oblique, and the third layer is Transfer the rotational torque that the second layer is subjected to to the handle. The third layer of the first rotating portion is a solid surface of the laminated stretch and is in a sloped state. When the first rotating portion is fitted with the screwing member, if the fitting space is restricted by other components The third layer may be a guiding surface and the first rotating portion is introduced into a narrow space to be engaged with the screwing member.
