Description of the invention: [Technical field to which the invention belongs] This creation is a technical field of ratchet wrenches. [Prior Art] According to the 'practical ratchet wrench structure', please refer to Appendix I, which is the applicant's application to the bureau on June 16, 1989 and approved by the hook office on April 11, 1990. 4 2 9 8 4 7 [Integrated ratchet wrench structure φ]] It includes at least a body 1, a surface layer 2, a driving body 3 and a ratchet set 4, wherein the body 1 is a surface layer 2 The surface layer 2 and the body 1 are made of different materials, and the hardness of the surface layer 2 is softer than that of the body 1; further, the body 1 is provided with a shaft hole at a proper position. 10, and can correspond to the accommodating chamber 2 表 of the surface layer 2, so that the driving body 3 and the ratchet group 4 can respectively receive the shaft hole of the accommodating chamber 20 and the body 1 which are pivotally disposed on the surface layer body 2 Within 1 inch, the ratchet set 4 can be maintained in proper Φ contact with the drive body 3 and the shaft hole 1 of the body 1. Although the above creations can indeed achieve the original purpose of creation, and are highly praised by the industry and the general operators, the applicants are not complacent because of the rapid development of technology and the capacity of the operators. Trying to study and improve, which makes it perfect and practical; and recently, after many times of updating the experimental test and summarizing the actual opinions of the manufacturers and consumers, the creators found that the following problems still need to be further improved: It is made of thin iron plate, that is to say, its steel thickness is thin 1303201. Therefore, when the pulling force is large, it will often cause severe distortion due to insufficient steel thickness. Or break, and then can not be reused as the biggest trouble for the industry and consumers. Therefore, how to develop an advantage that can retain the original design (ie, reduce its processing steps, increase production, reduce costs, prevent electrical conduction and insulation), at the same time, T can increase the ratchet wrench can withstand the force, to increase The place where it is used, and then the return to the city ## rate and competitiveness, this is a major issue that consumers are looking forward to, and more serious and urgent improvement. In view of this, the creator is actively developing research, and in order to improve the lack of the above-mentioned conventional ratchet wrench structure, the creator has made many years of experience in this product. After long-term efforts and experiments, he finally designed this creation— Body-wrapped ratchet wrench construction (2), all the consumers and manufacturers of the ship Jiahui. SUMMARY OF THE INVENTION The main content of the body-wrapped ratchet wrench structure (2) of the present invention is that a surface layer body of different materials and hardness can be directly coated on the outer side of the body which has been forged and heat treated. And the housing chamber of the surface layer can correspond to the class deviation_hole of the body, so that the simple group and the ratchet group can be accommodated in the shaft hole of the body, and the _ terminal of the driving group can be It can be located on the inner side of the surface layer, and can be used to reduce the production and reduce the processing steps of the ratcheting component and the appropriate contact. At the same time, it can also increase the torsion force that the ratchet wrench can withstand to increase the inner wall edge of 1303201 -01 and the inner wall edge of the cover body 5; and the ratchet set 4 includes at least the movable member 40 and the elastic body. 4丄 composition or by the movable member 4 〇, the elastic body * 1 and the abutting member (not shown in the figure, such as "balls, spring caps, etc."), and formed at the 40-end of the movable member with teeth 4Q1 And can force the control to change the spine by shifting the position of the twist 7 The position of the movable member 40 of the wheel set 4 determines the effective rotational direction of the driving body 3 驱动 of the driving group 3; the surface layer body 2 and the body 1 are the same material, and the hardness of the surface layer body 2 is higher than that of the body 1 The hardness of the surface layer 2 is formed on the outer side of the body i, and the receiving chamber 2 Q, the through hole 21 and the handle portion 22 are formed, and the receiving chamber 20 is connected to the body. Corresponding to the shaft hole 1〇1 of 1 and allowing the accommodating chamber 2 to be used as the end of the driving group 3 or the housing 5 is arranged; and the surface layer 2 is The driving unit 3 is composed of at least a driving body 3 and a pressing ink 31, wherein the driving body 30 can be at least divided into a quadrangular head 30 1 and a tooth portion 3 . 0 2. The shape of the class φ shaft hole 3 0 3 and the side hole 3 0 4, and the shaft hole 3 0 3 and the side hole 3 0 4 are connected to each other 'so that the button 31 and the spring (not shown When the force can be placed in the shaft hole 3 0 3 and then moved by force, it can be used as the basis for controlling the moving position of the positioning bead 35 which is located in the side hole 3 0 4 due to the change of the moving position of the button 31. When manufacturing It is only necessary to place a round iron material (not shown) on a forging die (not shown), and the initial embryo aspect of the body 1 is completed after processing by the forging machine (ie, having a thick body 1) In order to improve its rigidity), and then through the turning process (ie 1303201 f inner hole or drilling or turning the head i (10) end face, etc., such as: turning the shaft hole 1 〇 1 turning on the butterfly face Na Hung to complete the tillage - m The heat-treated square wire completes the required hardness of the body ^. Finally, the body 1 (including the head 1 〇 and the shaft portion (1) is placed in the injection mold - not shown) and utilizes the head (10) end face. The accuracy side of the reference surface and the shaft hole 1 〇^ after turning (that is, the shape of the class shouting reed) is used as the sharpening of the injection mold, so that the shape of the mold can be (4) The m package and the correction, in other words, the (4) cooling, the surface layer 2' can be formed and the surface layer 2 is covered with the body i; at this time, the accommodation body 2 of the surface layer 2 is caused. Corresponding to the small-diameter end of the shaft hole 1 0 1 of the body 1 which is eccentrically shaped, the drive group 3 and the ratchet stage 4 can be accommodated at the same time. The shaft hole i Q i _ of the lining body 1 is within the slamming edge, and the end of the driving group 3 can be located in the accommodating chamber 2 (10) of the surface layer 2, and the movable member 40 of the stomach wheel group 4 can be respectively Properly maintaining proper contact with the tooth portion 3 〇 2 of the drive group 3 and the inner working edge of the body member, the inner wall edge of the hole _ hole 1 〇i is effectively controlled by the action of the ratchet and the movable member 40 of the group 4. The driving of the driver stage 3 is the steering of the ^3 0 and the amount of torque that can be withstood; as far as the above content is concerned, it can be clearly seen that the creation is a partial improvement for the conventional annex I and the creation can be kept known. The advantages of the attachments - and can enhance the strength of the torsion that the body can withstand. Therefore, the changes in this creation are as follows:
