Abstract
A quick-release screwdriver structure includes a tool holder and a tool head embedded in a head portion of the tool holder. A fixing seat is sleeved outside the tool head; an inner wall of the fixing seat is provided with a notch, and a bottom surface of the notch is an inclined surface; a steel ball connected to a release ring is installed in the notch, and the steel ball contacts the tool head; and a movement of the release ring will drive the steel ball to move along a longitudinal direction of the bottom surface of the notch so as to lock or release the tool head. A new locking assembly is designed to act on a surface of the tool head so as to achieve locking and disassembly of the tool head.
