Abstract (en)
A wrench with a quick rotatable driving head includes a handle (40), a driving head (50) and a quick-disengaging unit (60). The quick-disengaging unit is composed of a fixing member (61) secured with the driving head, an operating member (62) inserted through the handle and fitted around the fixing member, and a restraining element (64) transversely provided between the fixing member and the operating member and the handle. The handle and the driving head can be separated by the quick-disengaging unit so that the driving head, with the quick-disengaging unit acting as a pivot, can quickly screw or unscrew a thread locking member, and the operating member can be restrictedly positioned on the fixing member by the restraining element, able to prevent the handle and the driving head from separating.
