Abstract
A power tool includes a function control mechanism to control operation of a drive spindle in a selected one of a rotary drive mode and a hammering mode. The function control mechanism includes a first ratchet that is mounted to rotate with the drive spindle, a second ratchet that is slidable from a first position to a second position, and a ring controller. The second ratchet is disengaged from the first ratchet when the second ratchet is in the first position, and is engaged with the first ratchet when the second ratchet is in the second position. The ring controller is coupled to a push ring that abuts against the second ratchet such that rotation of the ring controller results in movement of the second ratchet between the first and second positions.
