发明名称 Ratchet wrench with three operative positions
摘要 A ratchet wrench includes a drive member rotatably received in a body that includes a compartment extending from a first side toward and spaced from a second side of the body. A control member is pivotable between three operative positions to change the driving direction of the ratchet wrench. The control member includes a first end pivotably coupled to the drive member and a second end covering the compartment. The control member includes a control section selectively engaged with two pawls slideably received in the compartment and releasably engaged with teeth of the drive member. When the control member is in a second operative position, the pawls are engaged with the teeth of the drive member, allowing a handle of the body and the drive member to rotate in either of two directions driving the fastener, and not allowing free rotation of the handle relative to the drive member in either of the two directions without driving the fastener.
