Abstract

PROBLEM TO BE SOLVED: To provide a ratchet wrench that ensures a small backlash and appreciable performance. SOLUTION: A body with an operating handle has ratchet teeth around a square shank and has two locking pawls mounted at angles for alternate mesh with the ratchet teeth. Both locking pawls are spring-loaded in respective directions to mesh them with the ratchet teeth.

Reference numeral 3 denotes a square axis provided on the main body 1 around which ratchet teeth 4 are provided. In the present invention, the two locking claws 5 and 6 are engaged with the ratchet teeth 4 and when one of them engages with the ratchet teeth 4, the other locking claws are kept at an angle so as to be separated from the ratchet teeth 4 and the pins 7 and 8 are kept. To pivotally attach to the main body 1. If the locking claws 5 and 6 are arranged so as to alternately mesh with the ratchet teeth 4, the advance of the teeth with respect to the locking claws 5 and 6 is 1
/ 2, which is the same state as when the number of ratchet teeth is actually increased, and the torque is not reduced, and the swing angle is reduced to half of the conventional angle.
