Abstract
A reversible ratchet wrench includes a direction-selecting rotary knob disposed rotatably on a driving head and rotatable relative to the driving head between a clockwise position and a counterclockwise position such that, at the clockwise position, a pawl unit is connected between the driving head and a ratchet head so as to allow for clockwise co-rotation of the driving head and the ratchet head, while preventing counterclockwise co-rotation of the driving head and the ratchet head, and at the counterclockwise position, the pawl unit is connected between the driving head and the ratchet head so as to allow for counterclockwise co-rotation of the driving head and the ratchet head, while preventing clockwise co-rotation of the driving head and the ratchet head.
