New description: 【New technical field】 This creation is about the inner button type control structure of the ratchet wrench (2), which is mainly composed of the block, the ratchet and the wrench.敝 _ can get Jane:, and it is easier to reduce the work, to give better industrial value and practicality. [Prior Art] "Press, the knives of the cleavage or unloading of the nut, the general ripper, the plum wrench, the button, the adjustable wrench and the ratchet wrench, etc., among which the open end wrench and the plum wrench are The lion's secret surface 'only (four) inspection-rules _ combined _ secret, resulting in the use of the fresh, and the amount of wrenches and adjustable wrenches in use, although through the replacement of the sleeve size or the adjustment of the clip σ, It is convenient and practical to apply the lock-and-load operation for the multi-body specifications. However, it is difficult to refer to the use of the gestures and the repeated take-up actions due to the operation. To solve such problems, the industry has developed The ratchet wrench, with the ratchet block of the ratchet wrench and the ratchet, cooperates to unidirectionally drive the leaven to the idling, so that it can be integrated with the different specifications in addition to the different specifications. In addition to its practicability, it is not necessary to constantly change the gestures in its operation, so that it can solve the problem of inconvenient operation of other types of wrenches. With the existing ratchet wrench, it is mainly to provide a set of holes for the wrench head. a ratchet wheel is arranged, and a predetermined number of pockets are additionally arranged at the inner edge of the sleeve to fill the ratchet block, and a spring is further arranged between the rear part of the ratchet block and the inner wall of the pocket to push the ratchet block to make the spine The tooth block engages with the ratchet teeth on the peripheral surface of the ratchet wheel, and gives the ratchet block a margin of spring pressure. Thus, the action characteristic of the one-way ratchet is utilized, so that the ratchet can only be driven by the ratchet block when the wrench is controlled. One-way rotation, and the reverse direction will cause the idling effect of the wrench without causing the ratchet to rotate. Therefore, it will be more convenient to lock and unload the screwing member. However, in this functional architecture, in addition to causing it In addition to the complication of the components and the increase of the assembly time, the other part is filled by the ratcheting hole for the ratchet block, which is formed by the inner wall side of the sleeve hole 4 M437235 °, which is invisibly increased. The difficulty and cost of processing, plus the need to install the bomb I between the ratchet block and the inner wall of the tank, in the absence of proper positioning, it is difficult to ensure that the spring can be in the correct position, even during the assembly process. There is a problem of spring tripping, which leads to poor assembly. The product produces 'and its magazine has the problem of elastic fatigue. Over time, it may lead to the lack of correct action of the ratchet block. It is difficult to call it the ideal structure. It is necessary to try to solve the improvement. [New content] In view of the structural problems and possible problems and disadvantages of the conventional ratchet wrenches, the authors have made special efforts to carry out research and improvement. Based on their years of experience and technology in the side industry, they have developed the improved structure of the ratchet wrench of this creation. That is to say, the main purpose is to effectively simplify the structural composition of the ratchet wrench through the composition of the knot, thereby reducing the difficulty of assembling. The other purpose of the creation is to change the design of the ratchet block through the composition of the structure.
