Abstract
An electric ratchet wrench includes a body and a driving member rotatably mounted in the body and is rotatable about an axis. A ring gear is rotatably mounted to and moveable relative to the driving member, and the ring gear is rotatable relative to the driving member about a center axis of the ring gear. A power device is received in the body. A transmission shaft is rotatably mounted to the body. The transmission shaft has a end connected to the power device, and another end configured to switch between a meshing state meshed with the ring gear and a disengagement state disengaging from the ring gear. An elastic device biases the ring gear causing the center axis of the ring gear being inclined relative to the axis in the disengagement state and being parallel with the axis in the meshing state.
