Description

Technical area

[0001] The invention relates to a wrench structure, particularly to a wrench structure in which the drive part and the handle part rest on the plane when the main body rests on the plane. A larger gap is formed between the first and second bottom surfaces and the plane, making it more convenient to pick up the wrench. State of the art

[0002] The conventional wrench structure, which is a patent case of this applicant with the US patent number: US 11691263 B2, title: Wrench Structure, comprises: a main body having a drive part and a shaft, the shaft being connected to the drive part, the top and bottom of the shaft each forming a first surface and the left and right sides of the shaft each forming a second surface; the main body has a projection, the shaft being located between the drive part and the projection, the top and bottom of the projection each forming a third surface and the left and right sides of the projection each forming a fourth surface; the end of the main body forms a handle part, the handle part being far away from the drive part, the top and bottom of the handle part each forming a fifth surface and the left and right sides of the handle part each forming a sixth surface, a first connecting portion being provided between the handle part and the projection, connecting the projection and the handle part, the top and bottom of the first connecting portion each forming a seventh surface and the left and right sides of the first connecting portion each forming an eighth surface; and a second connecting portion is provided between the projection and the handle part, and the second connecting portion connects the projection and the handle part.

[0003] However, the shortcomings of this conventional wrench structure are: 1. As in Fig. As shown in Figure 2 of the U.S. patent application Ser. No. 4, the top and bottom surfaces of the shaft 12 each have a first surface 121. The first two surfaces 121 are parallel to each other. The top and bottom surfaces of the projection 13 each have a third surface 131. The top and bottom surfaces of the handle 14 each have a fifth surface 141. When the wrench is placed on a plane, the distance between the plane and the shaft 12, the projection 13, and the handle 14 is very small, making it difficult to pick up the wrench. 2. The top and bottom surfaces of the shaft 12 each have a first surface 121, and the first two surfaces 121 are parallel to each other. The top and bottom surfaces of the projection 13 each have a third surface 131. The top and bottom surfaces of the grip portion 14 each have a fifth surface 141. The shaft 12, the projection 13, and the grip portion 14 are all symmetrical structures. Object of the invention

[0004] The problem to be solved by the invention is as follows: In conventional wrenches, the distance between the plane and the shaft, the projection, and the handle portion when resting on a plane is quite small, making it difficult to pick up the wrench. In the wrench according to the invention, the drive portion and the handle portion rest on the plane when the main body rests on a plane. A larger gap is created between the first and second bottom surfaces and the plane, making it more convenient to pick up the wrench.

[0005] The technical solution to the problem is as follows: a wrench structure including a main body having a drive part, a shank, a projection, and a handle part. The shank, the projection, and the handle part have different thicknesses and widths. The shank, the projection, and the handle part have different heights relative to the drive part. The highest part of the projection has the greatest height relative to the drive part. The lowest part of the bottom of the projection has the greatest height relative to the bottom of the drive part. The shank has a first surface, a first bottom surface, a first connecting surface, and a first side surface. The projection has a second surface, a second bottom surface, a second connecting surface, a second side surface, and a third connecting surface.The handle part has a third surface, a fourth connecting surface, a third bottom surface, a third side surface, a fourth side surface and a fifth connecting surface.

[0006] The advantages compared with the prior art are as follows: The drive part, the shaft, the projection, and the handle part have different thicknesses and widths. The shaft, the projection, and the handle part have different heights relative to the drive part. The highest part of the projection has the greatest height relative to the drive part. The lowest part of the bottom of the projection has the greatest height relative to the bottom of the drive part. When the main body is placed on a plane, the drive part and the handle part rest on the plane. A larger gap is formed between the first bottom surface and the second bottom surface and the plane. In particular, a large gap is formed between the second bottom surface and the plane, so that the handle part and the projection make it easier to pick up the main body.When the user holds the handle part with their hand, their hand can rest on the second side surfaces, the fifth connecting surface, and the fourth side surfaces. The surface area of ​​the second side surfaces, the fifth connecting surface, and the fourth side surfaces is more favorable for the user's hand to exert the force to rotate the main body. The best place for the user's thumb to rest is the deepest part of the fifth connecting surface to rotate the main body. The fourth connecting surface is formed between the second surface and the third surface. When the hand holds the handle part, the fourth connecting surface can also be used to rest the hand stably. When holding the handle part, the user can place their fingers on the fifth connecting surface or the fourth connecting surface as needed. This makes it easier for the user to rotate the main body.The main body has two places where the user can place their fingers. These two places allow the main body to be rotated.
