Description of the invention: [Technical field to which the invention pertains] • This creation is related to a wire insertion design [Prior Art] A ratchet wrench modification, especially an improvement of a ratchet wrench in a ratchet block. As shown in Fig. 8, it is a conventional handle (there is a technique in the prior art: a ratchet wrench is provided, which has a grip inside the body 7 - a ratchet handle and a body 7 ' The ratchet 7 2 has a ratchet head 7 1 with two ratchet blocks 74 on the periphery thereof, and the two ratchets are replaced by = 3; the internal body of the body is provided with 7 nets 7 4 so as to be pivoted inside the body 7 at one end. 'and a ratchet block 74 - a second ratchet block 76, and is equipped with n # ratchet blocks 7b 箦7 7 connected to the body 7,:: the spines 4 are respectively set - the bombs ^ are eccentric between a ratchet block 74 The pivoting cam 8俾(4) is completely eccentrically positioned as the wheel 8 and is detached from the ratchet block 7 2 when the ratchet block is disengaged from the ratchet head 71, so that the two ratchet blocks 74 are forced to rotate and output torque to the guard The socket 7 3 _ _ 〇 操作 during operation 'by the eccentric position of the cam 8 , the card is selected to the first ratchet block 7 5 , ( 4 ) the second ratchet block ^ ^ to each ratchet 72 The one-way ratchet == and the need to install a variety of components in the installation, but also the waste of the day-to-day disposal in the assembly and reduce the production efficiency. 5 1279293 Ratchet wrench of this embodiment a body 1 , the body is connected to a grip 2 , and a receiving groove is formed in the body 1 to install a ratchet set 3 , the ratchet set 3 further comprising a ratchet head 3 1 , the ratchet head 31 has A workpiece holder 3 1 1 俾 is for splicing the workpiece; and a ratchet head 31 is disposed on the accommodating groove 1 1 and a ratchet block 3 2 is provided. The ratchet block 3 2 has a spine 'toothed portion 3 2 1 ' And the ratchet block 3 2 is biased by an adjusting rod 4 disposed outside the body 1 , and the ratchet portion 3 2 1 of the ratchet block 3 2 is engaged with the ratchet head 3 1 , and the ratchet block 3 2 is close to the periphery. A first opening 322 and a second opening 323 are respectively disposed on the upper side and the lower side, and the receiving groove χ 1 defines a first groove 1 1 1 and a second groove 1 away from the ratchet head 3 1 . 1 2, for respectively, an upper urging ring 5 1 and a lower ejector ring 5 2 are provided, and the upper ejector ring 5 1 has a first convex portion 5 1 1 and the first convex portion 5 1 1 a first left clamping portion 5 i 2 and a first right clamping portion 5 1 3 respectively extending to surround the first opening 3 2 2 , and the lower pushing ring 5 2 has a second convex portion 52 1 And a second left clamping portion respectively extending from the second convex portion 5 2 1 5 2 2 and a second right clamping portion 5 2 3 surround the first opening 3 2 3, and the second protrusion 5 1 1 is embedded in the first groove 1 1 1 'the second convex portion 5 2 1 is embedded in the second groove 1 1 2; a gap is reserved between each opening 3 2 2, 3 2 3 and the body 1 for the upper ejector ring 5 1 and the lower ejector ring 5 2, the space required for the operation. The cover body 6 is covered with a cover body 6, and the cover body 6 is respectively locked to the body 1 by a screw member 6 2, wherein the cover body 6 has a through hole 6 i for the The cover 6 of the cover 6 is further protruded from the body 6 to the workpiece 6 1 1 to protrude from the through hole 6 1 . The ejector rings 5 1 , 5 2 respectively provide the ratchet block 32 - a component of the ratchet head 31 of the 7 1279293 to achieve the purpose of meshing. When the adjusting lever 4 is interlocked, the ratchet block 32 is biased by the right side to the ratchet head 3 1, and the left clamping portion 5 1 2, 5 2 2 of each of the pushing rings 5 1 and 5 2 is f itself! A force is applied to the ratchet block 32 to apply a force to the ratchet head 31, and the ratchet block 3 2 is reset to the ratchet head 3丄 because the ratchet block 3 2 is interlocked to the left by the forehead 4 The (4) card abuts the ratchet 1 'presses the ratchet block 3 2 against the ratchet head 3 i for the ratchet 1 and the ratchet portion 3 2 1 of the ratchet block 3 2 to be coupled with each other, according to which the μ ratchet block 3 2 Reset to the ratchet head 3 1 . Therefore, the creation of the mouth is convenient in resetting only by the push ring 5丄, 5 2 = can maintain the reset effect, and also reduce the number of components on the manufacturing = the field is therefore large, that is, the production time is 'and at the same time The manufacturing cost of this creation is reduced and the number is greatly reduced; in terms of assembly, each push ring, 52 is easy to install', so it is time-saving in assembly. By clamping the ratchet block 3 2 by the ejector ring, the ratchet head 3 1 and the ratchet block 3 2 ^ ' can push the rings 5 1 , 5 2 to instantly produce a resetting effect. . Of course, there are still many examples in this creation, in which only the details change. π Refer to FIG. 3, which is the second embodiment of the present invention. The ratchet block is axially pierced with two slots 3 2 4, 3 2 5 respectively. Accommodate - play Bo 3 ^ push the bead 3 2 7 to protrude the ratchet block 3 2, the body! And: each bead body 3 2 7 sets two sets of card slot workers 3, workers 4 for the spines f, 3 1 when the pivot is inserted by the beads 3 2 7 for resetting; each left loses 5 1 2, 5 2 2 and each right clamping portion 5丄3, 5 2 3 and surrounding the circumference of the spine 8 1279293 wheel block 3 2 . Therefore, the ratchet wrench that already has the reset device can provide an auxiliary reset effect through the creation. Therefore, the reset structure through different wrenches can be helped to reset by the creation without cost and time. . Please refer to FIG. 4 to FIG. 7 , which is a third embodiment of the present invention. The left clamping portion 5 1 2, 5 2 2 and the right clamping portion 5 1 3, 5 2 3 are surrounded by the two slots. Between 324 and 325; therefore, only the minimum d contact area can be used to achieve the reset effect, so it can be applied to a small ratchet head with a small installation space. The above description of the embodiments is intended to be illustrative of the invention, and is not intended to limit the scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the above-mentioned objects, and is in accordance with the provisions of the Patent Law.
