Abstract

The invention provides a ratchet wrench. The ratchet wrench comprises a body, a ratchet, two braking blocks, two elastic pieces and a reversing piece. The material strength of the braking block is greater than that of the ratchet; in a ratchet wrench pulling operation, if the applied force exceeds the limited and bearable torsion at the meshed part of the ratchet teeth of the ratchet and the teethpart of the braking block to cause tooth breakage, the tooth part of the braking block is instantly meshed and positioned with a good ratchet tooth which is positioned behind the broken tooth and isengaged again, so that the effect of ensuring the operation and personal safety of an operator is achieved.
