Abstract: An electric ratchet wrench includes a driving member rotatably mounted in a body. A pawl device is pivotably mounted to the driving member. A ring gear is rotatably mounted around the driving member. A flexible transmission shaft includes a first end connected to a motor and a second end configured to switch between a meshing state meshed with the ring gear and a disengagement state disengaging from the ring gear. The motor drives the transmission shaft to rotate the driving member. The body can be manually driven to overcome a resistance which is larger than the torque outputted by the motor and which causes a tooth slippage phenomenon between the transmission shaft and the ring gear.

Abstract: A ratchet wrench structure includes a main body provided therein with a ratchet wheel, an actuating member and a restraining block positioned between the ratchet wheel and the actuating member. The restraining member has one side provided with two recessed portions, and the actuating member is provided with a position-limiting groove corresponding with the recessed portion, and an elastic member. When the actuating member is rotated, the elastic member will be actuated to push the recessed portion to have its front edge longitudinally and evenly pressing the recessed portion to enable the elastic member to support the restraining block in its entirety. Further, when the restraining block is stressed by rotation of the ratchet wheel, the restraining block can carry out reciprocating movement because of extension and contraction of the elastic member. Thus, the ratchet wrench structure can be simplified in number of components.
