AI Technical Summary
Existing wrenches often face difficulties in accessing tight spaces and achieving adequate rotational movement for loosening or tightening nuts and bolts during automobile repairs due to limited space and reach.
A hexagonal joint is designed to provide an extension and rotation function, allowing a wrench to be extended and rotated at any location by incorporating a cylindrical center and hexagonal rod structure, enabling seamless engagement with sockets and ratchet wrenches.
The hexagonal joint facilitates efficient rotation and extension of wrenches in confined spaces, reducing the need for cumbersome repositioning and minimizing required space, thereby enhancing operational efficiency and flexibility.

Abstract
Description
[Technical field]
[0001] This invention relates to a coupling for a wrench or the like, used primarily in automobile repair and machine repair. [Background technology]
[0002] When loosening or tightening nuts, bolts, etc. in automobile repairs, use the appropriate tool to turn them. Summary of the Invention [Problem to be solved by the invention]
[0003] Usually, when removing or installing automobile parts, bolts (hereinafter referred to as the object) are inserted into a wrench or the like and turned, but there are many situations where it is difficult to secure enough space to rotate them. In addition, with general hand tools, it is often difficult to reach the object with the tool. Therefore, the above-mentioned problem is solved by providing a combination tool with an extension function and a rotation function for a wrench (including a ratchet wrench, etc.). As a special addition, the history of tools is very old and there are many different types. We carefully investigated whether there were any similar tools that realized the functions of this invention. There are extension tools generally called extension bars, but as far as the inventor has researched, they are different in shape, function, and usage, so we are inventing and applying for this invention. [Means for solving the problem]
[0004] The hexagonal joint of this invention is a tool that can be used with wrenches, etc. The overall appearance is a hexagonal rod, but the tip is a drive angle and the center of the rod is cylindrical. A socket is inserted into the drive angle at the tip, an object is fitted into it, and the hexagonal joint of this invention is engaged with a wrench, etc. Alternatively, by inserting a ratchet wrench, etc., it is possible to extend it at any location, solving the problem of situations where it is difficult to secure space for rotational work. Effect of the Invention
[0005] As described above, the hexagonal joint of this invention can of course be extended to a wrench, etc., but by providing a cylinder midway through the hexagonal joint, it is possible to change the rotational position while keeping a ratchet wrench, etc. inserted into the hexagonal joint. [Brief description of the drawings]
[0006] [Figure 1] 1 is a diagram showing an embodiment of a hexagonal joint of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] Figures 1 and 1 show the hexagonal joint of this invention. It is used in conjunction with the combination wrench shown in Figures 1 and 2. Figures 1 and 2 show other tools that can be used to rotate the hexagonal joint shown in Figures 1 and 1, such as a double-ended ratchet wrench. Figures 1 and 3 show the socket. EXAMPLES
[0008] Fit the socket in Fig. 1, 3 into the tip (drive angle) of the hexagonal joint in Fig. 1, 1, and insert the hexagonal joint in Fig. 1, 1 into the spanner hole of the combination wrench in Fig. 1, 2. Slide the combination wrench in Fig. 1, 2 in the direction of Fig. 1, a, so that the hexagonal joint in Fig. 1, 1 can be rotated.
[0009] In the state shown in Figure 2, by holding a combination wrench or the like in Figures 2 and 2 in your hand and applying force in the direction of Figure 2, c or Figure 2, d, and rotating it, you can rotate and loosen or tighten an object fitted into the socket in Figures 2 and 3.
[0010] In the state shown in Figure 2, the hexagonal joint in Figure 2 and 1 and the combination wrench in Figure 2 and 2 remain engaged, and a working space must be secured within the circumferential range of the rotation radius of the combination wrench in Figure 2 and 2, and the force applied must also be changed depending on the direction. To rotate continuously, it is necessary to disengage the two once, reselect the angle of the hexagonal prism, and reengage them so that rotation can be performed in the minimum necessary space. A method for solving this problem is shown in Figure 3. In Figure 3, the combination wrench in Figure 3, 2 can be inserted into the hexagonal joint in Figure 3, 1 and slid in the direction of Figure 3, a or b to move it to the central cylinder of the hexagonal joint in Figure 3, 1, and disengage the engagement. This shape allows the hexagon to be re-engaged with minimal movement without having to remove either of them. At the same time, the work can be done with the minimum necessary rotational movement and space, which greatly reduces the amount of work required to re-select the hexagonal position with hand tools, saves time, and allows the tool to be extended at any position at the same time.
