Abstract

An electric socket ratchet wrench includes a body, a driving device rotatably mounted in the body, a pawl device coupled with the driving device, a power device providing a torque, a transmission device between the driving device and the power device, and a clutch device. The driving device includes a driving member having a non-circular hole for coupling with a fastener. The driving member includes an annular toothed portion coupled with the pawl device and an end toothed portion coupled with the transmission device. When a resistance smaller than the torque is encountered while the driving member is driving the fastener, the driving member continuously drives the fastener. When a large resistance larger than the torque is encountered at a position, the body is manually rotatable by a torque larger than the large resistance to forcibly drive the fastener through the position via the driving member.
