New description: [New technical field] The creation department is related to the structure of the ratchet wrench, especially the ratcheting wrench is provided with a bullet-proof groove, so that the elastic element is abutted against the tooth at an angle. The tooth structure between the tooth and the ratchet is more certain. - [Prior Art] As previously known, the conventional ratchet wrench structure, such as the U.S. Patent No. 5:9 9 2 2 4, is based on the structure: the body is provided with an appropriate length. a shank, the working end of the body is provided with a first receiving groove, and a second receiving groove having a smaller diameter is disposed near the shank of the first receiving groove, and the upper and lower sides of the second receiving groove are In a closed shape, the first receiving groove is in communication with the second receiving groove, and the second receiving groove is bored with a ballistic hole at a suitable position, and the elastic hole is longitudinally disposed; the ratcheting system is disposed at the first a ratchet wheel outer peripheral edge is provided with a ratchet portion of an annular array of teeth, and a center of the ratchet wheel is provided with a polygonal groove-shaped sleeve portion for screwing the screwing member; the tooth system is placed in the first In the two-receiver groove, a plurality of occlusal teeth are arranged on the front side of the toothing, and the occlusal tooth system is engaged with the ratchet portion; one end of the elastic element is received in the ballistic hole, and the other end of the elastic element is fixed on the tooth The teeth of the teeth are r» compliant with the ratchet portion. However, the missing part of the patent is that the tooth system is engaged with the inner side of the second receiving groove by the elastic member, so that the engaging tooth engages with the ratchet portion, but the elastic hole of the elastic member is drilled On the wall surface of the second receiving groove, if the curved wall surface of the second receiving groove is to be drilled, it is a very difficult processing procedure, because the elastic hole is sighed when drilling 3 The first-cavity wall surface, the system needs to be inclined at an angle. The drill bit is extended to the second cavity. The inside of the second cavity is aligned with the appropriate position of the curved wall surface, and the inclined elastic hole is drilled, that is, the elastic hole is An inclined hole having three directions of X:, Y-axis, and Z-axis, which is required to be drilled - a bullet hole is a structural defect thereof, and another patent case, the US Patent No. US 7 4 4 4 g 0 3 B 1, Taiwan Patent Application No. 〇9 6 2 5 8 ο 9, a kind of ratchet wrench, which is composed of a wrench tree, a knotted ratchet, a ratchet and a limit ring, wherein the wrench One end of the body is provided with a through-toothed slotted hole, and one of the ratcheting holes is provided with a ring of limiting ring ribs on one side and a peripheral edge of the other side. One ring is engaged with the ring groove, and a ratcheted arc-shaped accommodating groove chamber is further disposed at the shank of the ratchet hole groove; the knotted ratchet block is an arc-shaped banana shape, and one side of the inner arc concave portion The segment is provided with a ratchet tooth, and the other side of the concave portion of the inner arc is provided with a lower and flat sliding surface, and one side of the ratchet is provided with a stop surface at the edge of the arc, and the card is further provided. The arc outside the knot is provided with a spring that is ejected in the direction of the ratchet; the outer circumference of the ratchet-X is provided with ratchet teeth, and the inside is provided with a rocking hole groove, and both ends are provided with a limit ring. a groove; a circumference of the limiting ring is provided with a ring of engaging grooves; by the above-mentioned structure, the locking piece is provided with a spring at the outer fox convex portion, and the engaging ratchet block accommodates the body of the human wrench body together with the spring. The groove chamber is placed in the wrench, and the ratchet hole is inside the ratchet hole. The lower limit of the ring groove and the wrench body under the ratchet wheel is the limit of the two ribs = the limit position of the wrench body. The limit ring is matched with, . The % groove is closed and fixed 'the upper limit ring groove of the ratchet is limited to the limit ring. M417232. The structure of the patent does not need to drill a hole in the wrench body relative to the US patent 5979274. The wrench has less system. The processing cost is a relative advantage, but the patent structure also has the following shortcomings: 1. Please supplement the structure of the ratchet wrench as shown in the second figure of the patent publication. There is a wrench body 50, a knotted ratchet 6 0, spring 6 4, ratchet 7 0, a limit ring 80 and elastic buckle 90 and other six components, six components combined into a ratchet wrench, which is a more complex multi-component assembly structure and increase component cost . 2. Although it is not necessary to drill a bore hole on the wrench body, it is required to have a magazine slot on the rear side of the latching block 60, and the spring 6 4 is accommodated in the latching block 60 In the slot, after the forming of the latching block 60, a heat-retaining groove needs to be drilled after the forming, and the rear side of the engaging rocking block 60 is also curved, and the arc-shaped portion is also difficult to drill. The groove, and as shown in the fourth figure, the ballistic groove is located at the highest point of the arc surface. When the bit rotates rapidly and contacts the arc surface, the bit is easily displaced along the arc surface, and the drilling is performed. The position of the elastic groove is easy to be biased. The knotted block 60 needs to be drilled with a capacity groove system to increase the processing cost, and the diameter of the elastic groove is not large. When the small drill bit is drilled, the drill bit system is quite easy. fracture. 3. As shown in the fourth figure of the bulletin or the ninth figure, the magazine is in the longitudinal direction, and the spring 6 4 is abutted against the engaging ratchet 60. The direction of the force is also the longitudinal direction, as disclosed in the bulletin.
