Oscillating tool

A clamp arrangement for releasably securing an accessory having a radially open-ended aperture to a vertically oriented output spindle of an oscillating power tool that is rotationally driven about an axis by a motor, the oscillating power tool having a tool body with an exposed end portion of the output spindle projecting from an underside of the tool body, the clamp arrangement comprising:

• a clamp assembly coupled to the end portion of the output spindle of the oscillating power tool and including a first clamp member that moves axially relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp member of the clamp assembly is offset upwardly from the accessory permitting radial removal of the accessory from the clamp assembly;
• an arm having a user engagement portion positioned intermediate the underside of the tool body and the accessory and a pivot portion including a pivot axle, the arm being pivotally coupled relative to the tool body about the pivot axle between a first position, wherein the clamp assembly is in the closed position and a second position wherein movement of the user engagement portion of the arm causes the clamp assembly to be moved to the open position;
• and
• wherein the clamp assembly is arranged on the tool body in a position such that the accessory oscillates about a longitudinal axis that is located intermediate the pivot axle and the user engagement portion.

A clamp arrangement for releasably securing an accessory having a radially open-ended aperture to a longitudinally extending output spindle of an oscillating power tool that is rotationally driven about a longitudinal axis by a motor, the oscillating power tool having a tool body with an exposed end portion of the output spindle projecting longitudinally along said longitudinal axis from an underside of the tool body, the clamp arrangement comprising:

• a clamp assembly including first and second clamp members, the second clamp member being fixedly secured to the end portion of the output spindle at a fixed distance away from the underside of the tool body, the first clamp member being movably disposed on the output spindle between the second clamp member and the underside of the tool body for longitudinal movement aligned with said longitudinal axis between a closed position wherein the clamp assembly retains the accessory between the first and second clamp members and an open position wherein the first clamp member of the clamp assembly is longitudinally offset along said longitudinal axis from the second clamp member and displaced toward the underside of the tool body permitting radial removal of the accessory from the clamp assembly while the first clamp member remains coupled to the output spindle;
• and
• an actuator having a user engagement portion and being movably coupled relative to the tool body between a first position, wherein the clamp assembly is in the closed position, and a second position wherein the clamp assembly is in the open position;
• and
• wherein movement of the user engagement portion of the actuator causes the clamp assembly to be moved from the closed position to the open position.
