New description: [New technical field] This creation is about the ratchet wrench externally controlled structure (1), mainly through the composition of the structure to make the spine, ratchet and wrench head cover hole The difficulty of grouping can be simplified, and it is easier to make it easier to assemble, and to give more value to the industry to use value and practicality. [Prior Art] From the wrench tool for removing the screw such as the nut from the lock of the conventional ship lock, there are roughly the types of open wrenches, tempered wrenches, sets of miscellaneous hands, adjustable wrenches and ratchet wrenches. And the plum blossom wrench is only suitable for the locking operation of the single-size screw fittings due to the fixed-size design, which causes the use and inconvenience in use, and the sleeve and the adjustable wrench can be used in the system. The replacement of the sleeve size or the adjustment of the jaws gives the convenience and practicability of the locking and unloading operation suitable for multiple specifications. However, due to the constant change of gestures and repeated take-up actions, it is still difficult to use in operation. In order to solve such problems, the industry has developed a ratchet wrench. By the cooperation of the ratchet block of the ratchet wrench and the ratchet, it gives the one-way belt a one-way omnipotent energy, so that it can be used in the locking and unloading operation of the screwing member. In addition to the practicality of the multi-standard application, it is not necessary to constantly change the gesture, so that it can solve the problem of inconvenient operation of other surface wrenches. With the existing ratchet wrench, it is mainly used for the wrench lion making money - the fit hole is used to accommodate the ratchet wheel, and another predetermined number of radiant fill ratchet blocks are arranged in the fit hole and the ratchet. The rear part of the block and the Rongler are equipped with a spring _ _ wei, which makes the thorns and the ratchets on the circumference of the ratchet, and gives the ratchet block a margin of spring pressure, thus using the unidirectional ratcheting characteristics to make When the wrench is controlled, the ratchet can only be driven by the ratchet block to rotate in one direction, and the reverse direction will cause the wrench to have a idling effect without causing the ratchet to rotate, so that the locking operation of the screwing member will be more Convenience. ', and under this work at» architecture' to maintain the overall assembly relationship of the ratchet wrench, such as the first case of the 〇9 8 2 1 90 08 in the structural design, mainly in the ratchet block order system The horizontal M438352 is inserted into the groove, so that after the spring and the ratchet block are placed in the cavity, the c-ring is fastened to the ring groove and the ratchet block provided in the middle of the sleeve hole. In the slot, the positioning relationship between the positioning ratchet block and the sleeve hole is reached, and then the ratchet is placed by one end of the sleeve hole, and the other c-type buckle is fastened to the ring groove of the outer peripheral section of the ratchet wheel and fits The hole is opposite to the annular groove formed at the same time, and a limiting ring piece is sleeved in the lower part of the ratchet protruding sleeve hole, and a corresponding ring groove is formed between the inner diameter of the limiting ring piece and the outer diameter of the lower part of the ratchet ring. A c-type buckle is fastened, so that the ratchet can be firmly set in the sleeve hole of the wrench to complete its overall assembly. However, the structure of the upper ratchet wrench is assembled, because the two c-type buckles are required to be fitted with the upper and lower buckles, the ratchet wheel and the wrench sleeve hole and the ratchet wheel and the limit ring piece are combined. -c type buckle is used as the relationship between the ratchet block and the wrench sleeve hole, that is, it must be assembled and maintained by three sets of c-type buckles, except for the interlocking operation of the c-type buckle. The difficulty of the assembly, the complexity of its components and the increase of the assembly time, the need to solve the need to improve, on the other hand, the wrench sleeve hole for the ratchet block to fill the groove, It is difficult to ensure the spring energy by adding the spring between the ratchet block and the inner wall of the groove. In the right position, even in the assembly of the Kawasaki towel may have a spring jump problem, the guide ship with bad 瑕 _ _ ' and its spring is elastic fatigue problem, over time, it may lead to its ratchet block The lack of action is not true. To be real - and find ways to resolve those. [New content] In view of the problems and defects that existed in the structure of the conventional ratchet wrench, the creation and research improvement, based on its years of experience and technology in related industries, and then the ratchet of this work The improved structure of the wrench, that is, its main purpose is to effectively simplify the structural composition of the ratchet wrench through the composition of the structure, thereby reducing the difficulty of assembling. Type Another purpose of this creation is to change the design of the ratchet block and the pocket through the composition of the structure, so that the processing difficulty can be reduced and the final processing combination can be made easier. 5 M438352 Another purpose of this creation is to achieve the holistic appearance of its appearance through the composition of the structure, and then to achieve the simplification of its components, processing difficulty and assembly operations. Another purpose of this creation is to omit the structure of the spring pushing against the ratchet block through the composition of the structure, in order to avoid the spring fatigue, which may cause the dynamic material to be sure. In order to achieve the goal, the creation of the creation is mainly based on the provision of a predetermined diameter sleeve on the head of the wrench. The hole of the hole can be designed with a notch type or a sigma type, and the bottom edge of the inner circumference of the sleeve hole is set as a bottom edge convex ring, and the periphery of the sleeve hole is appropriately placed by the head. The top surface is provided with at least one or more troughs, and the ratchet blocks can be placed in the cavities, and the shape of the ratchet blocks is substantially conformed to the φ shape of the cuvettes, and the troughs can be accommodated in the cavities The shaft portion of the chamber is slightly smaller than the swing portion of the swing chamber, and a single peak tooth is formed on the inner edge of the swing portion. (4) The silky shouting towel section is provided with a horizontal embedding groove, and the one-way spine in the horizontal embedding groove (four) The end paste is provided with an i reduction surface, so that after the ratchet block is filled in the trough, the first c-type buckle drum is disposed in the lower ring groove of the sleeve hole and the horizontal direction of the ratchet block. The outer edge surface of the 1st C-clip buckle and the any-slope contact point of the obliquely pushing surface in the horizontally embedded groove are pushed to form an elastic performance, so as to facilitate the yaw actuation of the operating ratchet block, and according to It is maintained by the combination of the ratchet blocks, so that the ratchet block has no detachment from the pocket, and a ratchet is arranged on the upper end of the sleeve hole, including a ratchet shaft and a top edge extension. The outer diameter of the ratchet shaft is matched with the sleeve hole of the wrench, and a ratchet is formed on the outer circumference of the ratchet outer diameter, and a ring is formed on the outer peripheral surface of the ratchet shaft. The groove, the position of the ring groove is the same as the ring groove of the upper part of the sleeve hole. * A bottom edge concave ring is formed at the bottom of the bottom of the nest to match the inner circumference of the sleeve hole. The bottom edge of the bottom end of the convex ring, the helix is inserted into the sleeve hole of the wrench, so that the 2nd C-type buckle is fastened between the ring groove of the ratchet and the upper ring groove of the sleeve hole, achieving two The positioning of the combination relationship is also provided with a set of holes in the center of the ratchet. The set of holes can be seen by a wrench (10) cranes and mosquitoes;!: $ set the set of people p, ig when the ratchet_diameter In addition to the function of completely covering the periphery of the sleeve hole, in addition to the function of the ratchet wrench, it can better balance the simplification of its components, the reduction of the difficulty of the final processing assembly and the maintenance of the overall appearance. 6 M438352 [Embodiment] For the structure of the Qing, shouting, technical solution, and financial achievement, give further examples to the following: "Re-allocation.
