An electric ratchet wrench includes a driving member (21) rotatably mounted in a body (10) for driving a fastener. A pawl device (22) is pivotably mounted to the driving member (21). First and second ring gears (23, 24) are rotatably mounted around the driving member (21) and mesh with the pawl device (22). A direction switching rod (25) is pivotably mounted to the driving member (21). A transmission shaft (41) is rotatably received in the body (10) and includes an end connected to a motor shaft (311) of a motor (31). The other end of the transmission shaft (41) is connected to a bevel gear (42) disengageably meshed with the first and second ring gears (23, 24). The transmission shaft (41) can be driven by the motor shaft (311) to drive the bevel gear (42), the first and second ring gears (23, 24), and the driving member (21) to rotate. |
