Abstract:
A ratchet wrench includes a connecting section between a head and a handle. The connecting section includes a vertical connecting portion integrally connected to a first side of the head. An extension extends outward from a section of an outer periphery of the head. A first compartment extends from the first side of the head through a second side of the head and rotatably receives a drive member. A second compartment is formed in a portion of the inner periphery of the first compartment aligned with the extension and receives two pawls releasably engaged with the drive member. The second compartment extends towards the extension. A first radius from the outer periphery of the head to a rotating axis defined by the head is smaller than a second radius from the extension to the rotating axis.
