90115fiQ? I V. Description of the invention (1) _ [Practical background note] Press, the two to three years of the hand tool industry can be described as a ratchet wrench, such as a single j == the adoption of the sleeve ratchet wrench is absolutely low For the whole set of ratchet wrenches, the price of the socket wrenches of the two types must be matched with the sleeves of various sizes: the use of the sleeve ratchet wrench often needs to be more than a dozen sizes ^ For the large size of the sleeve ratchet wrench Sleeve torque ', so its head 2 is set to be the most suitable for this kind of socket ratchet wrench; like car; J = is a necessary evil, which is characterized by a small and light head. Especially its size from 8 cm to 23 cm is the main fatal injury of the ruler, the second largest, the ratchet block of the meter wrench is quite small, and its force surface size. Among them, there is a standard setting of the so-called " ANSI " Therefore, =, while Guo Guo's pair of small and highest torque ratchet wrenches is the most important issue, especially this year the United States as a whole ^ with 2 to take the main =:;: r has a market, only the spine; = hand Xiu sleeve ;, see the efficiency of the work; fish dung, and Ding Zhang μ ... See this year's light ratchet plum blossom under the core of 100 pieces, but they can not get rid of the predicament of insufficient torque, the second two :: combined illustration: Please refer to the twelfth figure, which is a-habitual ratchet wrench. The difference between the traditional ratchet wrench and the reverse ratchet wrench is only whether the ratchet block is shifted by the & to the door ^ ', but the force situation is the same, today only: no': j The ratchet wrench is described as follows, in which the wrench 1 is two Z $, one is on the inner wall surface, so that the ratchet tooth ^ and the ratchet gear 4 are mutually 1235696 Λ month amended case number 90115693 5. Description of the invention (2) 'And because the ratchet block 3 is a single-center design, the ratchet teeth between the ratchet block 3 and the ratchet gear 4 can be completely intimately engaged. However, since the ratchet block 3 is resisted on only one side, the ratchet block The back of 3 is suspended without any branches, so when the ratchet block 3 is subjected to a certain force, its suspended back is not resisted, so no reaction force will be generated. The ratchet block 3 will start with The supporting point on one side is a fulcrum for deflection so that the ratchet teeth on the other end of the ratchet block 3 are slightly disengaged. The seesaw effect is caused. The seesaw effect will cause the ratchet block 3 to be cracked only by the first three teeth meshing. The torque value of this conventional wrench is about 28kgf / m. Please note the above ratchet block It is only supported by a single rigid support 5 and only a few teeth are supported when it is stressed, so its torque value will be sufficient to suspend the ratchet with this design. It is necessary to increase the ratchet block and the head. To comply with "ANSI", once the head and ratchet block are enlarged, it will be dry and essential. Of course, it will not become a market. 2 main t-wrenches, lightweight flower wrenches gradually become this-to two years in the market ^: The so-called double-center ratchet block for ratchet plums is used to improve the above: the difficulty of insufficient torque with ten ^ pieces, please refer to the ^ double-center ratchet block 6 designed by Mingren is the beta and ratchet gear 7 of the present invention When they are locked with each other, although the ^ heart ratchet block meshes, it has only a single < thorn 1 ^ can be completely tightly connected to l 丄 < rigid fulcrum, which is also impossible to be > > 36 'This habit has double Torque of wrench 5 of center ratchet block 6: ^ = 36kgf / m, this torque value is higher than the first single value is Nearly 30% as much, between the ratchet teeth of the torque on the torsion blocks earlier, the present inventors on the CD and t, / is quite Cloth
