It is better and the hard metal material is integrally formed with - head i and by the head! a body portion 2 extending integrally downward, and a receiving space 3 is recessed in the first 1-side of the head portion, and the covering portion of the plastic material is used to cover the body portion 2 to the accommodating space. 3 The front side end face, and the front side of the head sill is formed with a step portion 5 for receiving a cover body 6. [New content] The outer wrench is made of plastic material-body covering the head. 1 The great torque is used as the ratchet mechanism to make the chisel rub. Because the division is the wall edge of the plastic step 5, it is easy to make the order. Department 5 production ah _ bad. X-difference, no filament length, high-torsion, hard metal material type:==3, the bearing structure is 'sole' and the side is recessed with an accommodating space; the core material is placed on the side of the predetermined range The integrally formed convex portion is formed in the working chamber, and the inner peripheral edge of the side peripheral wall forms a bearing-bearing portion, and the two wall edges make the wall edge and the accommodating space of the region of the kisser wheel rim structure, when the 5 M324565 ^ When the cover body is subjected to a torsion force, the bearing structure is integrally formed of a hard metal material, and can further withstand the abutting force of the cover body acting on the wall edge, thereby effectively preventing the deformation of the cover layer of the head portion, and Enhancing the structural strength. [Embodiment] As shown in the second to fourth figures, a preferred embodiment of the cover body of a lightweight ratchet wrench is provided, which comprises a core material 10 and a cover body. 20 and a cladding layer 30; wherein: _ the core material 10' is integrally formed by a rigid and hard steel metal, and includes a head portion 11 and a body portion extending downwardly from the head portion 11, the body The portion 12 is about twice the length of the head portion 11, and a recess is provided on the front side of the head portion 11. The first portion 13 is configured to form a ratchet mechanism (not shown), and a wall edge 14 is integrally protruded along a predetermined range of the circumference of the front end ring side of the front side peripheral wall of the accommodating space 13, and the wall edge 14 can be formed on the wall 14 In the embodiment, the wall edge 14 is formed on the entire circumference of the end ring side of the accommodating space 13 in the range of the upper edge of the end surface of the accommodating space 13 or the range of the entire circumference or the range of more than 180 degrees. The range 'and please refer to the fifth figure, the height of the wall edge 14 is slightly 1/2 of the thickness of the cover 20, and the wall edge 14 and the inner circumference of the accommodating space 13 An insertion portion 15 is formed, and a screw hole 151 for locking the cover body 20 is recessed on opposite end faces of the receiving portion 15. The cover body 20 is oppositely disposed on the receiving portion 15 A circular hole 21 is defined in the screw hole 151 of the receiving portion 15. The coating layer 30 can integrally cover the body 12 by using a lightweight polymer material, aluminum metal or magnesium alloy metal. Along the wall edge 14 of the ring end side of the head n, in the present embodiment, a lightweight aluminum metal is used. 6 M324565 for further understanding of this The characteristics of the creation of the structure, the use of technical means and the expected results, we will use the way of the creation of this creation, I believe that this can have a deeper and more specific understanding of the creation, as follows: First, Lee _ metal-body molding The core material 1Q, and the full riding range along the end side of the peripheral wall of the accommodating space 13 is a full-riding range of the body convex body wall 14' and then the metal coating layer 3{) is covered by the riding department η to the end of the head 11 of the record 14, the rhyme structure (10) is not set in the space, the space 13 inside the 're-two bolts to distinguish the round hole of the cover. Alignment»Hai Cheng set II 15 The screw hole 151 further turns the cover body 2 () into the mounting portion, and the garment is used, and the ratchet wrench assembler is used. When the torque is rotated, the pusher is pushed against the top of the wall. ^ Wall _ is formed from a hard steel metal body and has a thickness less than resistance to force' to increase its structural strength. ^ Effective =, and then the effect of the razor-shaped ship's axis can be stated as follows: The core material of the creation is a hard steel shape, = 'into the bearing part, and can be placed by the cover body, And the cover layer is further, so when the cover body is subjected to the torsion strength, the cover layer is unstressed on the head and the cover layer can be effectively prevented from being deformed and the structural strength is enhanced. 2, the ratchet wrench torque strength extracted from the surface of the surface is good quality and light weight. And it is not loose in the literature, ', this creation has its own difficult progress in similar products. 5 countries (10) on the technical information of this lining, and found that there is a phase _ Wei # 梅如, sacrifice as prepared The new special M324565 is a must, and the application is filed according to law. However, the above-mentioned ones are only one of the preferred embodiments of the present invention, and the equivalent structural changes in the application of the present specification and the scope of the patent application are intended to be included in the scope of the present patent. M324565 [Simple description of the figure] The three-dimensional appearance of the cover structure of the cover is the cover of each known ratchet wrench f. Guan Lin's creation is a cross-sectional view of the better solid face of the creation. The fifth drawing is a cross-sectional view of the head assembly of the preferred embodiment of the present invention.
