Description of the Invention: [Technical Field] The present invention relates to an open-end wrench and a method of manufacturing the same, and more particularly to an open-end wrench having two different materials at the same time and a method of manufacturing the same. [Prior Art] As shown in Fig. 1, the general open wrench 10 is formed by forming a steel material, although the wrench 11 of the head 11 has sufficient strength to be screwed, and the screw is removed. 12 should also have a certain degree of strength to provide sufficient ugly power, but the overall weight is not light, especially on the day of large screw construction, 'and in the dry work (such as telecommunications towers, steel truss arch bridges, etc.), Warehousing, shipping, or escrowing, and the inability to meet the requirements of lightweight users. Especially in the fields of drilling oil, platform, wind power, electric tower, high-rise building, mountain climbing or mountainous type, etc., the traditional materials are often criticized but helplessly accepted. Another problem faced by Dong Dong is that if the open-handed wrench is made of 10 2 alloy for weight reduction, the strength of the screw when screwing/screwing the screw is relatively insufficient. SUMMARY OF THE INVENTION The object of the present invention is to provide a material having a less rigid material as a lightweight open eyelet for a head and a grip. The object of the present invention is to provide a material having a less rigid material as a body structure and a manufacturing method. 201223708 In order to achieve the above objectives, the method includes the following steps: • The H-supplied open-end wrench manufacturing grip, the head has a notch. Then: the body 'body has a head and a head, the cover is covered with a notch, and the cover material is different from the cover of the body on the wrench to fit into a screw head end and the outer surface is formed - the above-mentioned cover body and body The socket ride method. The body head and the grip portion described above are formed by body molding. In order to achieve the above purpose, the open-end wrench of the present-screw head is widely used for screwing/screwing a single ^^s body and a cover. The body has a side = the head has a rear portion and a third plate body of the fork portion - the inner side == plate body, the outer side of the third plate body = a screwable screw / screw unloading screw - the wrench The first plate body, the second plate body and the == edge together define a cover opening. The cover mouth penetrates the body and the cover body covers the notch, and the cover body and the head portion are embedded and glued together. The material strength of the shell is greater than the material strength of the body. The degree of the plate can be greater than or greater than 32 mm. The other side of the outer side is outside the cover. The body of the invention is made of light alloy material, and the cover body is made of high-strength steel material, and the body of the cover body can be joined by using a lightweight and bulky body and a high-gluing material. The invention adopts the design of the dissimilar material and the joint joint, and ingeniously retains the preferred characteristics of the original material, 'after the dissimilar material is combined', the rigidity of the plate 201223708 of the wrench guard can be maintained, and the advantage of light weight is produced [embodiment] The preferred embodiments of the present invention are described in detail below. As shown in FIG. 2 to FIG. 5, the open plate hand of the embodiment is used for a screw/screw-screw head s (as shown in FIG. 5). The structure of the open-end wrench includes a body 20 and a cover. 30. The body 20 has a head portion 21 and a grip portion 22 such as a head joint. The head portion 21 has a further portion 21. The inner side portion 2111 of the fork portion 2U forms a notch 212 similar to us. The cover body 3 has a first plate body 31, a second plate body 32 opposite to the first plate body 31, and a third plate body 33 connecting the first plate body 31 and the second plate body 32. The surface of the outer side of the third plate body 33 is bent to form a wrench 33. The wrench 331 is used for screwing/unloading a screw head s (as shown in FIG. 5), the first plate body 31, the The outer edge contours of the second plate body 32 and the third plate body 33 collectively define a shroud 34 (shown in Figures 2 and 4). The bonding between the cover 30 and the main body 20 is applied by a gluing method, but not limited to this method, the shovel 34 is inserted into the fork 211 of the main body 2 to make the third plate 33 of the cover 30. Corresponding to the position of the notch 212, and covering the notch 212, the cover 3 is fitted to the head 21 of the body 2 (as shown in FIG. 3 and FIG. 5), so as to contact the screw head s. The first verticle 331 and the second plate body 31 of the connection 331 are made of the same material and integrally formed. In the above embodiment, the material strength and density of the cover 30 is greater than the material strength of the body 20 to cope with the rigidity required for the 201223708 screw/screw head s. Moreover, the material density of the cover 3G is greater than the material density of the body 20 to achieve the lightweight advantage of the open wrench. Further, as shown in FIG. 5, in the above embodiment, if the working width d (ie, the width of the π331) of the plate opening 331 is larger, the county indicates that the relative volume of the open-end wrench is larger, and the opening is at this time. The weight of the wrench is more important. For example, if the working width d of the π 331 is equal to or greater than 32 ug, then

In the above-mentioned implementation, the outer portion 2112 of the head portion 211 of the head portion 21 is exposed outside the cover body 3112 with respect to the outer side edge 2112 of the inner side edge 2111, so that the first plate body 31 and the second plate are formed. The body 32 is placed on the other side of the 2 ιι. Of course, part of the first plate body and part of the second plate system can be extended to the portion of the grip portion 22 to provide better torsional stress of the body 2, and the grip portion 22 can also be provided. At least 20 weights. Open the opening 221 (or slot) to reduce the performance of Figure 6 and refer to Figure 4 and Figure 5. The manufacturing method of the open-end wrench in this embodiment comprises the following steps: Step _, the "20" body 2 which provides the enamel has a head portion 2i and a grip portion 22' having a head-notch 212. Step illusion, outside the head, the sleeve - the second material cover 3G, and the material body covering the notch 212'. The outer surface of the cover 30 corresponding to the notch 212 forms a plate opening 33 The wrench 331 is used for screwing/unloading a screw head s. The manner in which the cover 30 and the body 20 are sleeved can be applied by a gluing method (= 201223708 is not limited to this method). In the above embodiment, the first material may be aluminum, magnesium or iron or an alloy thereof, and the second material may be die steel, chrome molybdenum steel or chrome vanadium steel. In an embodiment of the present invention, the body 20 is made of a first material (for example, an aluminum alloy), and the cover 30 is made of a second material (for example, chrome molybdenum steel). The commercial torque torque requirement (643N-M) is 743.524~1141.639NM by the German industrial standard DIN-3113, and its weight is expected to be 38~40% lower than that of pure steel hand. The invention is characterized in that the body of the invention is made of light alloy material, and the cover body can be made of die steel, chrome molybdenum steel or high-strength steel material, and can utilize a lightweight and bulky body, and high The rigid strength of the cover of the cover is in contact with the screw workpiece, and then the gluing process is used to fit the cover into the body, which is initially estimated to greatly reduce the weight of the wrench. The invention adopts the design of different materials and joints, and ingeniously retains the length of the original material, and after the combination of the different materials, the rigidity of the wrench wrench can be maintained, and the weight is reduced. In the above, it is merely described that the present invention is an embodiment or an embodiment of the technical means for solving the problem, and is not intended to limit the scope of the invention. That is, the equivalent changes and modifications made in accordance with the scope of the patent application of the present invention or the scope of the invention are covered by the scope of the invention.
