Description

Wrench structure

The present invention is related to a wrench structure, especially a wrench structure in which different heights and widths are formed between the handle, the bump and the handle, and the bump has a maximum height, when the body When placed on a plane, the handle and the handle are in contact with the plane, and a gap is formed between the handle and the first connecting portion and the plane.

According to our previous knowledge, the commonly used wrench structure is also the patent case applied by the applicant. Taiwan patent case number: 105115249, certificate number: I579114, patent name: wrench structure, the structure of the patent case lies in: a wrench structure , which includes: a body 10, the system is provided with a handle 11, the upper and lower sides of the handle 11 are provided with a first surface 111, and the upper and lower sides of the handle are respectively provided with two The first recess 112, the first recess 112 is recessed on the first surface 111, the handle 11 is provided with a first protrusion 113, and the first protrusion 113 protrudes from the first surface 111 Upper and lower sides; one end of the handle 11 is provided with a first rotating part 12, and the first rotating part 12 is an open end; the other end of the body 10 is provided with a second rotating part 13, The second rotating part 13 is a quincunx end, the second rotating part 13 is far away from the first rotating part 12, and the upper and lower sides of the second rotating part 13 are respectively provided with a second rotating part 13. Two faces 134 and a third face 135; the handle 11 is provided with a first length 31, the first length 31 is the minimum length of the handle 11, and the maximum length of the first protrusion 113 is the second length 32, the ratio of the first length 31 to the second length 32 is four to one to two to one, the thickness of the handle 11 is the first thickness 33, and the minimum thickness of the first recess 112 is the second thickness 34, the thickness of the first protrusion 113 is the third thickness 35, and the thickness of the first rotating part 12 is the fourth thickness 36.

But the lack of this conventional wrench structure is:

Please refer to the third figure of the patent publication, if the wrench structure is placed on a plane, such as when it is placed on a table, the plane and the handle 11, the first protrusion 113, the first rotation The distance space formed between the part 12 and the second rotating part 13 is quite limited, so it is not easy to pick up the wrench structure.

In view of the lack of the above-mentioned conventional structure, the inventor has been engaged in manufacturing, production and design experience in related industries for many years, and finally a product with a wrench structure that can solve the conventional disadvantages comes out.

In the conventional wrench structure, if the wrench structure is placed on a plane such as when placed on a desktop, the plane and the handle, the first protrusion, the first rotating part and the second rotating part The distance space formed between them is quite limited. In the wrench structure of the present invention, different heights and widths are formed between the shank, the bump and the handle, and the bump has the maximum height. When the body is placed on a plane, it is like a desktop When, the handle portion and the grip portion abut against the plane, a gap is formed between the handle portion, the first connecting portion and the plane.

The present invention relates to a wrench structure, which includes: a system with a driving part, a handle part, a first surface and a second surface, a bump part, a third surface, a fourth surface, a grip part, a fifth surface, a sixth surface, a first connecting part, A seventh surface, an eighth surface and a second connection part, the system is provided with the driving part, the handle part, the second connection part, the protrusion part, the first connection part and the handle in sequence The handle part, the driving part, the handle part, the second connecting part, the bump part, the first connecting part and the handle part are integrally formed, the handle part, the bump part, the handle Different heights and widths are formed between the portion and the first connecting portion.

Different heights and widths are formed between the handle, the bump and the handle, and the bump has a maximum height. When the body is placed on a plane, the handle, the handle and the When the planes abut against each other, a gap is formed between the handle and the first connecting portion and the plane, and the handle and the first connecting portion are easier to pick up the wrench structure. When the user holds the handle part with his hand, he can put his fingers against the first connecting part according to personal needs. The seventh surface and the eighth surface are in the shape of a concave arc, which is more conducive to applying force to rotate the handle. The main body, the system has the seventh surface and the eighth surface, both of which can be touched by fingers and have the operability of rotating the main body. When the wrench structure is taken, the palm of the hand can be directly held on the protruding part, so that it has gripping properties.

In order to make the committee members and those skilled in this art fully understand the effect of the present invention, the structure and composition of the present invention will be described below in conjunction with the drawings and figure numbers, but the following descriptions are only used to explain the implementation of the present invention For example, it is not intended to limit the present invention in any form, so any modifications and changes made under the spirit of the present invention should still fall within the protection scope of the present invention.
