Abstract
In accordance with one aspect of the present invention, a combination ratcheting and helical driver is disclosed. In the unlocked position the hand tool coverts downward linear force into rotary motion. In the locked position the hand tool operates as a ratcheting driver. The locking device locks the helical drive shaft of the hand tool in a retracted position such that the helical drive shaft is substantially positioned within the handle body. A locking main body is adjacent to a chuck assembly. The locking main body selectively combines with a shoulder abutment adjacent to the handle assembly to lock the helical drive shaft in the retracted position.
