Abstract
A ratchet tool includes a bar movably received in an operation space defined between an inner periphery of a cylindrical space in the head of the ratchet tool and a flat surface defined in an outer periphery of the cylindrical body of the driving mechanism. The bar is pushed toward two wedge-shaped areas in the operation space to control the effective direction of the driving mechanism. The bar is pushed to either one of the two wedge-shaped areas by two positioning units which are movably received in the cylindrical body. The tow positioning units are shifted alternatively by a shifting member mounted on the rod the quick release device which controls a bead for securing a socket mounted on the driving member of the driving mechanism. The efficient directions and the socket are both controlled by one-time operation of the quick release device.
