Description

Joint structure

The present invention is related to a joint structure, in particular, a joint structure in which the first fitting part or the second fitting part is fitted with the third fitting part or the fourth fitting part, and the plurality of first wrenches are connected by the body, and the body can be used to connect the first wrenches.

As we know before, the commonly used joint structure, such as Taiwan Patent Case No. 099210774, Certificate No.: M394205, Patent Name: Improvement of Socket Wrench, includes: An improvement of a socket wrench, provided with a receiving portion 22 and a plug-in portion 23.

However, the shortcomings of this commonly used joint structure are:

1. Please refer to Figure 7. In order to connect the multiple wrench bodies 20, the clamping hole 221 needs to be fitted with the sleeve joint column 30. Although the clamping hole 221 is a twelve-sided groove, the clamping hole 221 of this twelve-sided groove is a twelve-sided shape by multiplying the four-corner accommodation hole 231 by three. The angle between the two sides of each groove in the twelve-sided groove of the clamping hole 221 is ninety degrees. The clamping card 221 is different from the general twelve-sided groove structure of a screw-fitting part. The screw-fitting part is hexagonal, and the twelve-sided groove is a hexagonal groove multiplied by two. The angle between the two sides of each groove of the twelve-sided groove is 120 degrees. The clamping hole 221 cannot directly rotate the screw-fitting part, and the expandability is insufficient.

2. The multiple wrench bodies 20 can be extended and connected in series, and the four-corner sleeve joint column 30 is then fitted with a sleeve part and rotated. The wrench body 20 needs to be assembled with the sleeve joint column 30 before the threaded part can be rotated.

3. The processing of providing the annular groove 222 in the clamping hole 221 is relatively difficult and has room for improvement.

In view of the above-mentioned shortcomings of the conventional joint structure, the inventor, with many years of experience in manufacturing, production and design in the industry, finally came up with a joint structure product that can solve the conventional shortcomings.

In the conventional joint structure, the clamping hole cannot directly rotate the threaded part, and the wrench body needs to be assembled with the sleeve joint column to rotate the threaded part, which is insufficient in expandability. In the joint structure of the present invention, the first sleeve part or the second sleeve part is sleeved with the third sleeve part or the fourth sleeve part, and the plurality of first wrenches are connected by the body. The body can be used to connect the first wrenches, and the body has expandability.

The present invention relates to a joint structure, which is used in a hand tool structure, and includes: a body, one end of which is provided with a first sleeve part, and the other end of which is provided with a second sleeve part; the first sleeve part and the second sleeve part can be sleeved with various commonly used composite wrench structures, box spanner structures or open spanner structures; the second sleeve part and the first sleeve part have the same axis, and a first axis is provided at the axis of the first sleeve part and the second sleeve part. In two-dimensional view, the first axis has a first vertical line.

The first fitting part or the second fitting part is fitted with the third fitting part or the fourth fitting part, and the plurality of first wrenches are connected by the main body. The main body can be used to connect the first wrenches, and the main body is expandable.

In order to enable the members of the Jun Bureau and those familiar with this technology to fully understand the effects of the present invention, the structure and composition of the present invention are explained below with diagrams and figure numbers. However, the following is only used to explain the implementation examples of the present invention and is not intended to limit the present invention in any form.
