Technical field
[0001] The invention relates to a wrench structure wherein the main body has a first end, a second end, and a third end. The first end forms a first drive part, the second end forms a second drive part, and the third end forms a fourth drive part. The wrench structure of the invention has the first drive part, the second drive part, and the third drive part for different tools, thus providing the main body with greater expandability. State of the art
[0002] The previously filed patent case of this inventor with Taiwanese patent number 110111583, document number I779540, US patent number US 11691263 B2 and the title "wrench structure" includes: a main body comprising a drive part and a shaft, wherein the shaft is 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, with 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, the handle being located far from the drive part, the top and bottom of the handle each forming a fifth surface and the left and right sides of the handle each forming a sixth surface, a first connecting section being provided between the handle and the projection, connecting the projection and the handle, the top and bottom of the first connecting section each forming a seventh surface and the left and right sides of the first connecting section each forming an eighth surface; and A second connecting section is provided between the projection and the handle, and the second connecting section connects the projection and the handle.
[0003] However, the shortcomings of this conventional wrench design are: 1. The projection 13 has a polygonal shape. The top and bottom surfaces of the projection 13 have the same third faces 131. The projection 13 serves only for holding by the user and has no further extendable functions. 2. The drive unit 11 can be equipped with a ratchet mechanism to rotate screw elements. There is only one part for rotating the screw elements. 3. As seen from the side view in Fig. As shown in Figure 2 of the US patent document, the top and bottom of the shaft 12 have the same first surfaces 121, which are parallel to each other. The top and bottom of the projection 13 have the same third surfaces 131, and the top and bottom of the handle 14 have the same fifth surfaces 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, so that the user cannot easily pick up the wrench. Object of the invention
[0004] The problem to be solved by the invention is as follows: In the prior art, the projection has a polygonal shape. The top and bottom surfaces of the projection have the same third faces. The projection serves only for gripping by the user and has no further expandable functions. In the invention, the main body has a first end, a second end, and a third end. The first end forms a first drive element, the second end forms a second drive element, and the third end forms a fourth drive element. The wrench structure of the invention has the first drive element, the second drive element, and the third drive element for different tools, thus providing the main body with greater expandability.
[0005] The technical solution to the problem is as follows: A wrench structure comprising a main body having a first end, a first handle part, a second end, a second handle part, and a third end, wherein the second end has the greatest thickness between the top and bottom, wherein the third end has the greatest width between the left and right widest points, wherein the highest point of the second end has a height difference to the first end and the third end, wherein the first end forms a first drive part, the second end a second drive part, and the third end a fourth drive part, wherein the main body has a central axis, wherein the main body is symmetrical about the central axis, the central axis being the centerline of the main body, wherein the first end has a first surface and a first bottom surface, and wherein the first handle part has a second surface and a second bottom surface.
[0006] The advantages compared to the prior art are as follows: The main body has a first end, a second end, and a third end. The first end forms a first drive part, the second end forms a second drive part, and the third end forms a fourth drive part. The wrench structure of the invention has the first drive part, the second drive part, and the third drive part for different tools, thus offering the main body greater expandability. The first handle part, the second end, the second handle part, and the third end have different thicknesses and widths. The second end has its greatest thickness between its top and bottom surfaces. The third end has its greatest width at its widest points on the left and right. The first end, the second end, and the third end have different thickness variations relative to the first and second handle parts.

[0018] The advantages of the wrench structure of this invention are as follows: 1. The main body 10 has a first end 11, a second end 13, and a third end 15. The first end 11 forms a first drive part 110, the second end 13 forms a second drive part 130, and the third end 15 forms a fourth drive part 150. The wrench structure of the invention has the first drive part 110, the second drive part 130, and the third drive part 130 for different tools. The main body 10 has improved expandability for rotating different tools. 2. The first handle section 12, the second end 13, the second handle section 14, and the third end 15 have different thicknesses and widths. The second end 13 has its greatest thickness between its top and bottom surfaces. The third end 15 has its greatest width at its widest points on the left and right. The first end 11, the second end 13, and the third end 15 have different thickness variations relative to the first handle section 12 and the second handle section 14. The first end 11, the second end 13, and the third end 15 also have different width variations relative to the first handle section 12 and the second handle section 14, so that the main body 10 has a better three-dimensional effect. 3. The top and bottom surfaces of the first end 11 form the first surface 111 and the first base surface 112. The top and bottom surfaces of the second end 13 form the third surface 131 and the third base surface 132. The top and bottom surfaces of the third end 15 form the fifth surface 151 and the fifth base surface 152. The first end 11, the second end 13, and the third end 15 have different thicknesses and widths and create differences in height, giving the main body 10 a more three-dimensional appearance. 4. As in Fig.As shown in Figure 2, the highest point of the second end 13 has the greatest height compared to the first end 11 and the third end 15. When the main body 10 is placed on a plane, the third base surface 132 rests on the plane. Gaps are formed between the first base surface 112, the second base surface 122, the fourth base surface 142, and the fifth base surface 152 and the plane. The first handle section 12, the second handle section 14, and the third end 15 all serve to conveniently pick up the main body 10. 5. Between the second handle section 12 and the second end 13, the first connecting surface 133 and the second connecting surface 134 are formed. Between the second end 13 and the second handle section 14, the third connecting surface 143 and the fourth connecting surface 144 are formed. The first connecting surface 133, the second connecting surface 134, the third connecting surface 143, and the fourth connecting surface 144 provide more stable support for the hand. That is, when holding the main body 10, the hand can reliably rest on the third end 15, and when holding the main body 10, the fingers can rest on the second end 13, providing a more secure grip. 6. The two sides of the main body 10 successively form the first end 11, the first side surfaces 123, the third side surfaces 136, the second side surfaces 135, the fourth side surfaces 145, the fifth side surfaces 146 and the third end 15, which create a difference in width. 7. The second drive part 130 forms the third drive part 1301 at the bottom. The size of the third drive part 1301 is smaller than that of the second drive part 130. The main body 10 has four drive parts of different sizes, namely the first drive part 110, the second drive part 130, the third drive part 1301 and the fourth drive part 150. 8. When the third base surface 132 rests on the plane, the groove 16 forms a larger gap for lifting the base body 10.
