Power tool adapter

A power tool adapter for being quickly connected and disconnected to a first power driven rotary drive bit, the first drive bit having an outer periphery, the outer periphery including a recess, said power tool adapter comprising:

• a. an inner sleeve having a first end and a second end, said first end including an opening for accessing a cavity within said inner sleeve, said sleeve including at least one radially extending opening, said cavity being sized to complementarily receive at least a portion of the first drive bit such that the radially extending opening is generally aligned with the recess in the first drive bit, said first drive bit including a keyed portion which is rotatably fixed to a complementarily shaped portion of said inner sleeve, said second end of said inner sleeve having a second rotary cutting bit secured thereto;
• b. a locking ball radially and slidably disposed within said radially extending opening;
• and
• c. an outer sleeve having a cavity slidably receiving at least a portion of said inner sleeve therein, said outer sleeve being movable from a first position, wherein said outer sleeve maintains the locking ball in a radially inward position with respect to said inner sleeve such that the locking ball is positioned within the recess of the first drive bit, in a first direction to a second position wherein the locking ball is permitted to move to a radially outward position with respect to said inner sleeve to permit the locking ball to be positioned away from the recess of the first drive bit, and from the first position in a second direction to a third position wherein the locking ball is permitted to move to a radially outward position with respect to said inner sleeve to permit the locking ball to be positioned outwardly from the cavity of the inner sleeve when the first drive bit is installed into the cavity of the inner sleeve, said outer sleeve being biased toward said first position.

A power tool adapter for being quickly connected and disconnected to a first power driven rotary drive bit, the first drive bit having an outer periphery, said power tool adapter comprising:

• a. a base sleeve having a first end and a second end, said first end including an opening for accessing a cavity within said base sleeve, said cavity securely receiving at least a portion of the first drive bit, said base sleeve having an outer periphery, said outer periphery including a recess;
• b. an inner sleeve having a first end and a second end, said first end of said inner sleeve including an opening for accessing a cavity within said inner sleeve, said inner sleeve including at least one radially extending opening, said cavity being sized to complementarily receive at least a portion of said base sleeve and the first drive bit such that the radially extending opening is generally aligned with the recess in the base sleeve, said first drive bit and said base sleeve being rotatably fixed to said inner sleeve, said second end of said inner sleeve for receiving a second rotary cutting bit;
• c. a locking ball radially and slidably disposed within said radially extending opening;
• and
• d. an outer sleeve having a cavity slidably receiving at least a portion of said inner sleeve, base sleeve and said first drive bit therein, said outer sleeve being movable from a first position, wherein said outer sleeve maintains the locking ball in a radially inward position with respect to said inner sleeve such that the locking ball is positioned within the recess of the first drive bit, in a first direction to a second position wherein the locking ball is permitted to move to a radially outward position with respect to said inner sleeve to permit the locking ball to be positioned away from the recess of the base sleeve, and from the first position in a second direction to a third position wherein the locking ball is permitted to move to a radially outward position with respect to said inner sleeve to permit the locking ball to be positioned outwardly from the cavity of the inner sleeve when the first drive bit is installed in the inner sleeve, said outer sleeve being biased toward said first position.
