  • Patent number: 6070501
    Abstract: A ratchet tool has a ratchet body carrying a ratchet mechanism including a gear and a pair of pawls resiliently urged into engagement with the gear by spring-loaded balls. A handle is releasably received on a post which projects from one end of the ratchet body and is retained thereon by a spring-loaded ball receivable in a circumferential groove in the handle bore to accommodate free spinning thereof. A latching pin in the handle is selectively insertable in any of a plurality of recesses in the ratchet body to lock the handle to the body. A reversing sleeve is rotatably carried by the other end of the ratchet body for engaging the pawls to selectively control the direction of the ratcheting movement. The reversing sleeve has a tubular post which forms a part of an axial push-pull quick-release coupler for releasably retaining a bit in engagement in an axial bore of the ratchet gear.
