Abstract

A ratchet structure comprises two tooth blocks that are pivotally disposed and pushed by an elastic pushing structure. The tooth blocks also cooperate with a tooth portion of a joint. A protrusion of an outer cover is abutted against one of the tooth blocks, such that the other tooth block will be engaged with the tooth portion of the joint, thus producing the anti-reverse effect. Moreover, the tooth blocks are easy to assemble since they're pivotally disposed.

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to the technology of hand tools, and more particularly to a ratchet structure. [Prior Art] Since the ratchet structure has a back-stop effect of one-way rotation, it has been widely used in various tools and devices since its development. Under the research and development of many parties, the ratchet technology has gradually matured and later developed. The structure that can adjust the direction of the ratchet reverse direction, such as the technology of the Republic of China patent application number "096216535" and the patent name "ratchet wrench working head structure", but after the actual use, it is found that the reverse direction of the ratchet should be adjusted. The middle direction knob must be rotated, but the direction knob is not easy to apply force, and often has the disadvantage of being too tight and difficult to rotate. Therefore, the technology has been developed on the market, which can adjust the ratchet wheel to reverse the direction. It is easier; one of the technologies of the Republic of China Patent Application No. "093122236" and the patent name "High Torque Ratchet Driver", as shown in Figure 1, is a connector B that is pierced in a base A. For connecting the tool or the device, and the outside of the joint B has a tooth portion B1, the base A has a receiving groove A1 and a displacement groove A2, the receiving groove A1 The joint B is disposed, and a first tooth block All and a second tooth block A12 are disposed in the receiving groove A1. A spring A13 is further disposed between the first tooth block All and the second tooth block A12. On the side of the seat A, there is a 201031498 elastic magazine A3 and a steel ball A4, and an outer cover C is disposed outside the base A. The outer cover C has a first block C1, a second block C2, and a displacement block. C3 and three grooves C4, the first block C1 is opposite to the first block A1 in the receiving groove A1, and the second block C2 is opposite to the second block A12 in the receiving groove A1. The displacement block C3 is received in the displacement groove A2, and the steel ball A4 is received by the spring A3 to be received in one of the grooves C4 of the outer cover C. When the reverse direction of the ratchet wheel is adjusted, the outer cover is rotated clockwise. C, as shown in Fig. 2, the steel ball A4 is displaced into the other groove C4 of the outer cover C, and the displacement block C3 is moved to one end of the displacement groove A2, and the first block C1 will Blocking the first tooth block All, so that the joint B is rotated clockwise, the tooth portion B1 of the joint B will engage with the second tooth block A12, and the joint B is interlocked with the base A, if the clock is rotated counterclockwise Connector B, The joint B pushes the second tooth 'block A12 toward the first tooth block All and compresses the spring A13 to displace the second tooth block A12 and disengage from the tooth portion B1 of the joint B, so that the joint The head B is idling; otherwise, the outer cover C is rotated counterclockwise. As shown in Fig. 3, the steel ball A4 is displaced into a further groove C4 of the outer cover C, and the displacement block C3 is moved to the displacement groove. The other end of A2, the second block C2 will block the second block A12, so that the joint B is rotated counterclockwise, and the tooth B1 of the joint B will mesh with the first block A1, so that the joint B In conjunction with the base A, if the joint B is rotated clockwise, the joint B pushes the first tooth block All toward the second tooth block A12 and compresses the spring A13 to make the first tooth block All. The displacement 4 201031498 is disengaged from the tooth portion B1 of the joint B, and the joint B is idling; it can be seen that the reverse direction of the ratchet can be easily adjusted by rotating the outer cover C. However, in the foregoing technique, the first tooth block All The second tooth block A12 has no positioning structure in the receiving groove A1, and is only accommodated in the receiving groove A1, so the components are assembled.
