Abstract
A ratchet wrench having a flexible positioning structure includes a drive bar, a rotary head, and a locking button. The drive bar includes a fork arm, an axial hole, and a radial hole communicating with the axial hole. The rotary head is pivotally connected to the fork arm; the rotary head includes a round housing, a plurality of positioning recesses disposed on the round housing, and a pivot axis passing through the rotary head and two ends of the fork arm. The pivot axis is perpendicular to the radial hole. The locking button includes a flexible fastener inserted through the radial hole and a latch bar disposed in the axial hole. The flexible fastener is flexibly movable in association with movement of the latch bar, so that the latch bar is engaged with or released from any of the positioning recesses.
