New Description: [New Technology Field] This creation is related to ratchet wrenches, especially a ratchet wrench that prevents the nut from coming off. [Prior Art] In the structure of the conventional ratchet wrench, the end of the wrench body has a perforation for wearing the nut, so that one of the drive rings accommodated in the perforation can screw or loosen the nut. However, since the perforation is completely penetrated through the top and bottom sides of the wrench body, the nut of the ratchet wrench can easily fall out of the perforation when the driving ring of the ratchet wrench is passed through the nut, so that the nut and the screw cannot be well combined. , causing the operator to constantly reinstall the nut back into the perforation, and adjust the position between the nut and the screw until the nut is locked to the screw, which is quite inconvenient to use; and, in the lock or disassembly During the process of the nut, the ratchet wrench may cause slippage and increase the trouble of disassembling the nut, and may even cause work injury. [New content] The main purpose of this creation is to provide a ratchet wrench that prevents the nut from coming off to increase the convenience of disassembling the nut. In order to achieve the above objectives, the ratchet wrench provided by the present invention comprises a wrench body, a drive ring, a pawl, a positioning component and a retaining ring. The wrench body has a perforation on both sides of the m-passing portion, and a chamber recessed by the peripheral wall of the perforation; the driving ring is rotatably disposed in the perforation of the wrench body and has a set in the center The M363967 hole is connected, and the outer ring surface has a ring tooth portion; and the μ掣 claw valley is disposed on the wrench body to the τ X" toothed portion, and the tooth portion_claw 'forces the claw - the ring of the outer ring of the ring of the tree ring _ the top of the drive ring _ the top of the drive ring:: inwardly extending the m; the radial sleeve hole of itself. 4 the opening is smaller than the drive ring

The phenomenon of slippage between the wrenches is used to increase the use of the upper two spines. [Embodiment] The following preferred embodiments are listed in conjunction with the drawings to describe the structure and function of the present invention in detail. , σ Please refer to the first and second figures, which are provided with a ratchet wrench (10) according to a preferred embodiment, including a wrench body (2G), a drive ring-claw (4G), and a toggle (5H-position components _ and (70). The wrench body (20) has a - head (22), a through-hole (24) on the top and bottom sides of the through-head (22), and two (four) holes (24). a top end of the top end of the protrusion (26) extending radially, wherein the tenon (26) at the top end of the through hole (24) has a first recess (262). The wrench body (20) further has a perforation (24) an arc-shaped chamber (28) formed by the recess of the peripheral wall, and a valley hole (282) formed by recessing the peripheral wall of the chamber (28). The M363967 drive ring (30) is mounted in the through hole (9) of the wrench body (10). And can be rotated in place in the perforation (24). The drive ring (3_ central has a coaxial corresponding to the 1 (24) socket hole (32) for the socket nut, and has a inner ring mask • Ring tooth (34) with outer ring #36 (36). The claw (4〇) is mounted in the chamber (28) of the wrench body (2〇) and is on the front side. W. 卩 (42), can engage the ring gear (42) of the drive ring (30), and The rear side f has a left concave portion (44) and a right concave portion (10); in addition, the claw (40) has a connecting hole (48) for the top and bottom sides of the tooth. The dial member (50) has a dial portion. (52) and a connecting portion sentence, wherein the connecting portion (54) extends downward from the bottom surface of the dial portion (52) and is disposed in the connecting hole (10) of the claw (4〇) to make the dialing member When the dial portion (n) of (5〇) is subjected to an external force, the pawl (4〇) can be moved in the chamber p8). - Please cooperate with the (4) three diagrams, the positioning component _ is mounted in each of the holes (282) of the wrench body (10), and has a ball (62) and a spring (64), wherein the spring (64) is respectively separated by its ends Abutting against the circumference of the ball (62) and the receiving hole (282) to provide a spring force to push the ball (62) against the left concave portion (44) and the right concave portion (46) of the claw (4) Among them, the tooth portion (42) of the pawl (4) is forced to abut against the ring tooth portion (42) of the drive ring (30). The stop ring (70) is coaxially sleeved on the top edge of the drive ring (30), and has a second recess (72) in the outer ring mask, and the second slot (72) communicates with the wrench body (2) a first groove (262) for inserting a buckle (74) into the card, so that the stop ring (7 is fixed to the wrench body (20); in addition, the inner ring surface of the stop ring (7〇) is along The radial extension of the flange (76) itself, the opening (78) formed by the retaining edge (76) will be smaller than the sleeve hole (32) of the drive ring (30). M363967 The ratchet wrench of the present invention ( 10) When the nut (80) is placed through the socket (32) of the drive ring (3〇), as shown in the fourth figure, the nut (80) will be blocked by the retaining ring (70) ( 76) to block, can not pass the edge (76) _ into the hole (four) and is limited to the sleeve (32) of the drive ring (30). As a result, when the user is tight or loose When the nut (80) is used, the nut (8〇) will not be disengaged from the sleeve (32) of the drive ring (3), and the ratchet wrench (1〇) will not slip. The operation of disassembling the nut (8G) is mixed, and #然 can reduce the occurrence of work injury.
