ABSTRACT:
A power tool adapter which can be quickly connected and disconnected to a first power-driven rotary bit having an outer periphery includes an inner sleeve having a first end and a second end. The first end includes an opening for accessing a cavity within the inner sleeve. The sleeve includes at least one radially extending opening. The cavity is sized to complementarily receive at least a portion of the first bit. The first bit is rotatably fixed to the inner sleeve. The second end of the inner sleeve receives at least a portion of a second rotary bit. A locking mechanism is operatively engaged with the inner sleeve. An outer sleeve having a cavity slidably receives at least a portion of the inner sleeve. The outer sleeve is movable from a first position, wherein the outer sleeve maintains the locking mechanism in engagement with the first bit to lock the first bit to the inner sleeve, in a first direction to a second position wherein the locking mechanism is disengaged from the first bit to permit the first bit to be removed from the cavity of the inner sleeve, and from the first position in a second direction to a third position wherein the locking mechanism is removable from the cavity of the inner sleeve to permit the first bit to be installed into the cavity of the inner sleeve. The outer sleeve is biased toward the first position.
