Abstract
Illustrative embodiments of ratchet tools are disclosed. In one embodiment, a ratchet tool may comprise a handle extending along a handle axis and housing a motor, a head coupled to the handle at a first end of the handle, the head supporting an output shaft configured to be driven by the motor to rotate about an output axis, the output axis being substantially perpendicular to the handle axis, a ratchet mechanism coupled between the handle and the output shaft, the ratchet mechanism configured to restrict rotation of the output shaft in a first direction and to allow rotation of the output shaft in a second direction opposite the first direction, and a direction control configured to switch the first direction associated with the ratchet mechanism between a clockwise and a counterclockwise direction, the direction control being coupled to the handle and spaced apart from the head along the handle axis.
