Abstract
A driving tool includes a driving shank having a handle for rotating the driving shank and having an engaging hole formed by two or more spring blades for receiving a fastener, and an actuating device for actuating the spring blades to move radially inward and to force and grasp the fastener to the driving shank, for preventing the fastener from being disengaged from the driving tool inadvertently. The actuating device may include a barrel slidably engaged onto the driving shank for moving the spring blades to grasp the fastener to the driving shank with such as an inclined engagement. A control ferrule may be used to move the barrel relative to the driving shank.
