[Prior Art] At present, the development of hand tools in Taiwan is quite mature, and it has become a limited In the industry, manufacturers mostly change the structure and materials, and aim at: The production of new products that meet the needs of the people, in order to achieve a more comfortable use and practicality. σ In terms of hand tools, the use of wrenches and nesting tools is the most common. For screw-on tools, the design of the screw-shaped tool sleeve σ is a good way to turn the screw. And what is the key factor in the traces of the four (4) silk.凊With reference to the first _*, the structural design of the sleeve portion of the wrench is shown. The socket (4) of the wrench 10 is mainly composed of a plurality of _ set accommodating notches 112 and a circular convex surface 1 ,, the accommodating gap The 112 series is provided with the chamfering angle 21' of the matching screw head 20 to prevent the nut 2 〇 from causing a more fragile chamfering angle 21 during the pulling process, and the arc convex surface 111 is for the top. The cut surface 22' of the damper 20 is pushed against the nut 2 () during the pulling process.

The bottom corner ιΐ3 of the mouth u of the mouth u makes the right angle of the king set. It is obviously not easy to have the stress on the wrench structure to concentrate excessively on the angle of the angle; and the setting is slightly right angle: in the forming At the time of manufacture, it is quite difficult to achieve through milling or squaring. In addition to the above problems, the ratio of the circular convex depth D of the conventional wrench 1 〇 口 u to the circular convex width M is 】 :2' and the shallower convex surface (1) makes the abutment area of the cut surface 22 of the nut 20 relatively small, thus resulting in It is worth noting that the force of the turn is easy to slip when the nut is turned over. The creator of the case has studied and deepened the idea in view of the above-mentioned problems. After many research and developments and trials, he finally created ^ A ratchet sleeve structure of a wrench. [New content] The main purpose of the present invention is to provide a ratchet (four) structure of a wrench, mainly comprising a ratchet wheel inside the wrench body, the ratchet has a sleeve, and the socket is composed of a plurality of circles.

The application for the correction of the reed 7 is made by the person who changes the width of the cover. The width of the cover is larger than the width of the circular convex surface, so that the ratchet is set on the nut. The convex surface and the nut cut the mask 2 to the top abutment area without generating excessive idling. The second purpose of this creation is that the ratio of the fitting of the ratchet sleeve structure to the width of the garment (H) and the width of the tolerance gap (N) is 1:1.7~1.9, so that the sleeve 5 is When the nut is turned, the arc abutting surface of the circular convex surface and the nut cutting surface is large and not easy to slip, and the y y λ ^ circular convex surface has a large arc-shaped structure 'having flexibility to: the effect of the surface' Prevents the cutting structure of the nut from being broken. A further object of the present invention is that the bottom corner of the creation of the notch is rounded and the stress at the time of pulling the nut is optimally dispersive, and the appearance of the lack of σ & ^ , , , The corner has a small arc-shaped design that prevents the wrench power C from being too large and the damage of the k-shaped mouth portion ensures that the ratchet sleeve structure is not easily damaged. & the purpose of the ratchet sleeve structure of the creation wrench, including: the wrench body, with the right, '--------------------------------------------------------------- The inner edge of the ratchet is provided with a set of mouths, and the peripheral edge of the set of slits has a plurality of spaces π, and a plurality of arcuate convex faces are formed between the accommodating notches, so that the accommodating notch is deep and the sound is weak.

As described above, the ratio of the ice-to-width of the accommodating notch of the ratchet sleeve structure of the Φ 'the original wrench is 1: 1.71 - the preferred embodiment; the other embodiment is the missing The ratio of the depth of the 卩 to the width of the accommodating gap is ^: 1.75 ° 5 M399000 August 12, 1999 ΗApplication for repair [Implementation] In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation Please refer to the following section for a brief description of the following: · First, please refer to the figure 2 and 3, the ratchet sleeve structure of the wrench provided in the present embodiment is mainly inside the wrench body 30. The ratchet wheel 40 is fixed to the inside of the wrench body 30 by a C-shaped buckle 60. The ratchet body 40 is sleeved on a nut 20, and the wrench body 30 is abutted against the ratchet wheel 40 through a latching structure 50. The unidirectional turning operation is performed, wherein: the wrench body 30 is formed into a head portion 31 at one end, and the shank portion 32 is formed at the other end. The head portion defines an accommodating space 313, and the inner space of the accommodating space 313 is provided. a recess 314 and a set of recesses adjacent to the wall of the handle 32 a space 311 and a pocket 312; the ratchet 40 has a ratchet 41 formed on the outer edge and a ring recess 411' on the inner ring. The inner edge defines a sleeve 42 for the sleeve nut 20. The sleeve 42 is formed with a plurality of sleeves 42. And a circular arc convex surface 421 formed by the plurality of spaced-apart ring-shaped inwardly extending between the receiving recesses 422; the ratchet 40 is disposed on the head of the wrench 30 The accommodating space 313; the C-shaped buckle 60' is fastened to the ratchet 50 and the annular recess 411, 314' of the accommodating space 313 of the wrench body 30 to restrict the ratchet 40 from moving out of the accommodating space 313; The structure 50' has a card block 51, a guiding slider 52, a top member 53 and a magazine 54.

The latching block 51 is engaged with the ratcheting teeth 41 of the ratchet wheel 40 by the latching teeth, and (4) the retaining member 53 is partially depressed by the slot (10) and pushed against the recess 512 of the latching block 51. The slider slides sideways with the side of the card block 51 to keep the card block in proper positioning, and the wrench can perform a one-way turning operation. The above is the main component of the creation embodiment and The configuration description is difficult to make this creation. _Materials and their Wei, as explained below: Please refer to Figure 4 to show the name of the ratchet sleeve of this creation. The sleeve 42 of the ratchet 40 is the creation. The main feature is that the arcuate convex surface 41 of the sleeve is a large arc-shaped structure. When the sleeve 4 2 is sleeved on the nut and the plate is moved, the (four) 22 of the nut 2G and the circular convex surface 421 In order to prevent the slippage phenomenon when the plate is turned, the creation is made with a large arc-shaped structure, and the nut 20 and the set of π 42 are turned in the process. The full abutment does not occur. In addition, the circular convex depth D increases, and the receiving notch depth H also increases, and the vacancy π depth H is compared with the accommodating notch width N#. The design is ^ 1.7~1.9 ' Through the above structural ratio, the nut % chamfer 21 can be more deeply accommodated in the accommodating notch 422, so that the circular arc convex surface 421 and the nut 2 tangential surface 22 2 have a larger It is effective to prevent the nut 2G from slipping. The ratio of the π depth Η to the accommodating gap width N is 1:1 71 or ι: 7 M399000
