发明名称 High-torque reversible ratcheting wrench
摘要 A reversible ratcheting wrench includes a handle having a head, a drive member rotatably received in a hole, and a pawl slidably received in the compartment that is defined in an inner periphery delimiting the hole and that is communicated with the hole. A plurality of teeth are formed on a toothed side thereof and have a radius of curvature larger than that of teeth on an outer periphery of the drive member. When the pawl is in either ratcheting position, a portion of the teeth of the pawl meshes with the teeth of the drive member and the other portion of the teeth of the pawl are disengaged from the teeth of the drive member, leaving gap to avoid the seesaw effect that damages the teeth of the pawl and that reduces the torque-bearing capacity.
