Abstract (en)
A reciprocal switching structure of a ratchet wrench is provided and includes a case (100), a gear assembly (200), two gear racks (230, 240), a reciprocal switching mechanism (500), and a transmission unit (600). The case (100) has a first end and a second end, wherein the second end is adjacent to a gripping part of the ratchet wrench and is opposite to the first end. The gear assembly (200) is pivotally disposed in the case (100). The two gear racks (230, 240) engage or disengage from the gear assembly reciprocally. The reciprocal switching mechanism (500) is disposed in the case (100) and includes two push rods (510, 520) and at least one reciprocal switching member (530). The transmission unit (600) pivotally is disposed in the case, and is pivotally connected between the two gear racks (230, 240) for driving the two gear racks to be displaced.
