More Information
Summary:The aim of the utility model is to provide a ratchet wrench. The front end of the ratchet wrench is provided with a ratchet handle. The ratchet wrench is characterized in that the ratchet handle is provided with a groove body interpenetrating from the flank, and the front end of the groove body is provided with a rib connecting the upper edge and the lower edge of the ratchet handle. A needle bearing and an eccentric shaft are inserted into the rear end of the ratchet handle, an active guide sleeve is arranged in an opening of a ratchet yoke, and the ratchet yoke containing the active guide sleeve is arranged in the groove body. Because the ratchet handle is provided with the groove body interpenetrating the side edge and the front end of the groove body is provided with the rib connecting the upper edge and the lower edge of the ratchet handle, the ratchet handle can avoid generating deformation for collision, falling or long-term use owing to the reinforcement of the rib. As a consequence, the service life of the ratchet wrench is extended.
