[0003] a main body forming a projection, wherein the shaft is 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.
[0004] The shortcomings of this conventional wrench design are as follows: 1. The projection 13 has a polygonal shape. The top and bottom surfaces of the projection 13 each have an identical third surface 131. The projection 13 serves solely for handling by the user and has no other functions. 2. The drive unit 11 can be equipped with a ratchet mechanism to rotate various screw elements. There is only one point at which the screw element can be rotated. 3. How Fig. As shown in Figure 2 of the US patent publication (side view), the top and bottom of the shaft 12 each form an identical first surface 121. The two first surfaces 121 are parallel to each other. The top and bottom of the projection 13 each have an identical third surface 131. The top and bottom of the handle 14 each form an identical fifth surface 141. When the wrench is lying 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.

The two sides of the main body 10 successively form the first head 11, the first ribs 16, the second head 13, the second ribs 17, the third ribs 171, and the third head 15.
[0020] How the side view in Fig. Figure 4 shows that, viewed two-dimensionally, there is a first distance 181 between the first surface 111 and the first base surface 112, a second distance 182 between the second surface 121 and the second base surface 122, a third distance 183 between the third surface 131 and the third base surface 132, a fourth distance 184 between the fourth surface 141 and the fourth base surface 142, and a fifth distance 185 between the fifth surface 151 and the fifth base surface 152.

[0022] Furthermore, it will be noted that Fig. 6. Referenced. Fig. Figure 6 shows a perspective view of the connection with tools of the wrench structure of the invention. A first tool 20 has a polygonal shape. The first tool 20 fits into the second fitting section 130. A second tool 30 has a polygonal shape at its end. The second tool 30 fits into the fourth fitting section 150. Through the first fitting section 110, the second fitting section 130, and the fourth fitting section 150, the wrench structure offers three points for connection with tools of different sizes.
[0023] The third fitting section 140 is square. A tool has a square head, like the square head of a socket. The square head fits into the third fitting section 140. The tool can form a reinforcing grip to turn the first fitting section 110, the second fitting section 130, and the fourth fitting section 150.
[0024] Furthermore, it will be noted that Fig. 7 referenced. Fig. Figure 7 shows a perspective view of the second embodiment of the wrench structure of the invention. In this embodiment, the third head 15 has three bottle opening parts 153, one of which coincides with the side 1502. The three bottle opening parts 153 are connected to each other and arranged on the same side.
[0025] Furthermore, it will be noted that Fig. 8 Referenced. Fig. Figure 8 shows a perspective view with tools of the third embodiment of the wrench structure of the invention. In this embodiment, a third tool 40 is provided, which is a ratchet structure. The third tool 40 is rotatably received in the first fitting section 110. The second fitting section 130 is designed as a circular receptacle. A fourth tool 50, which is also a ratchet structure, is rotatably received in the second fitting section 130. The fourth tool 50 is larger than the third tool 40. The second fitting section 130 can have various shapes.
[0026] Fig. Figure 9 shows a perspective view of the fourth embodiment of the wrench structure of the invention. In this embodiment, the second shaft 14 does not form the third fitting section 140; however, the third fitting section 140 may be provided on the first shaft 12.
[0027] The advantages of the wrench structure of the invention are as follows: 1. The main body 10 has a first head 11, a second head 13, and a third head 15. The first head 11 forms the first fitting section 110, the second head 13 forms the second fitting section 130, and the third head 15 forms the fourth fitting section 150. The wrench structure of this invention has the first fitting section 110, the second fitting section 130, and the third fitting section 140 for different tools. The main body 10 offers improved expandability for connection with different tools. 2. The fourth pass section 150 forms the bottle opening parts 153, which have the function of opening bottles. 3. Based on the second points above, the fourth fitting section 150 forms the bottle opening parts 153. The main body 10 comprises the first fitting section 110, the second fitting section 130, the fourth fitting section 150, and the bottle opening parts 153. The wrench structure is expandable for connection with various tools and for turning various screw elements, and the bottle opening parts 153 function for opening bottles. 4. The second head 13 forms the second fitting section 130, and the third head 15 forms the fourth fitting section 150. The fourth fitting section 150 is larger than the second fitting section 130. The main body 10 has two different specifications due to the second fitting section 130 and the fourth fitting section 150. The main body 10 can rotate two screw elements of different specifications. 5. The first head 11, the first shaft 12, the second head 13, the second shaft 14, and the third head 15 have different thicknesses and widths. The widest point between the left and right sides of the third head 15 is the widest. The first head 11, the second head 13, and the third head 15 have different thickness variations compared to the first shaft 12 and the second shaft 14. The first shaft 12 and the second shaft 14 also have a thickness difference compared to the first ribs 16 and the second ribs 17. These at least three thickness variations give the wrench structure a more three-dimensional appearance. 6. The first head (11), the first shaft (12), the second head (13), the second shaft (14), and the third head (15) have differences in width. These at least three differences in width give the wrench structure a better three-dimensional appearance. 7. The first shaft 12 forms the first ribs 16, giving it an approximately cruciform cross-section. The second shaft 14 forms the second ribs 17, giving it an approximately cruciform cross-section. The first shaft 12 and the second shaft 14 ensure structural rigidity and can reduce weight. 8. The cross-section of the first shaft 12 is approximately cruciform, as is the cross-section of the second shaft 14. They have a height difference with the first head 11, the second head 13, and the third head 15, which gives the main body 10 a better three-dimensional appearance. 9. As in Fig. As shown in Figure 2, when the main body 10 is placed on a plane, the first base surface 112, the third base surface 132, and the fifth base surface 152 lie on the plane, while the second base surface 122 and the fourth base surface 142 form a gap to the plane. This makes it easier to lift the main body 10 by the first shaft 12 and the second shaft 14. 10. A finger can be inserted into the fourth pass section 150. When the finger is bent, the fourth pass section 150 is held in place by the finger, thus preventing loss of the main body 10. The fourth pass section 150 therefore serves as a loss prevention device. 11. As in Fig. As shown in Figure 6, the first tool 20 fits into the second fitting section 130. If the first tool 20 is a connecting rod, the main body 10 and the first tool 20 form a T-handle which has the function of turning a socket. 12. A socket wrench has a square head that fits into the third fitting section 140. The socket wrench has a relatively long handle that can be used as a reinforcing handle. The socket wrench is used to turn the first fitting section 110 or the fourth fitting section 150.
