CONSTITUTION: A jog-shuttle type ratchet wrench comprises a body part (110), a head part (200), a rotary shaft (226), and a jaw (230). A circular hole (112) is formed on one side of the body part, and a detent is received in the body part. The head part includes a housing (210) and a ratchet gear (212). The housing is installed in the circular hole to be rotated. The ratchet gear is formed on the outer surface of the housing. The bevel gear is composed of first and second gear parts (222, 224). The first gear part is coupled to one end of a controller (214) to be rotated. The second gear part is in gear with the first gear part to rotate with the first gear part. The rotary shaft is coupled to the second gear part to rotate with the second gear part. The jaw is screwed on the outer surface of the rotary shaft. |
