ABSTRACT:
A ratchet tool includes a handle, a tooling sleeve, a first pawl, a first elastic member, a second pawl, a second elastic member, a retaining ring, and a dialer. The outer circumference of the tooling sleeve received in the handle is disposed with teeth. The pawls and the elastic members are contained in the handle. Each of the pawls is disposed with teeth and a post. The retaining ring covers up the pawls and the elastic members and is secured to the handle. The dialer is pivoted to the retaining ring to change work direction of the tooling sleeve by moving the pawls as driven by the posts linked to the dialer when the dialer is turned to either side.
