ABSTRACT:
A ratchet device comprises a control body, a ratchet body, and a ratchet shifter. The control body is provided with two sets of arresting members symmetrical to each other. The ratchet body is provided with a toothed portion which is engaged with two of the four arresting members at the time when the control body is turned clockwise or counterclockwise, thereby resulting in enhancement of torsion and stability of the ratchet body. The tooth number of the toothed portion of the ratchet body can be so increased as to enhance maneuverability of the ratchet device, without compromising the torsion of the ratchet body.
