Abstract
A power sander includes a casing bounding a space in which a sanding plate is mounted for cyclical motion in parallelism with a plane of a support surface of the sanding plate. A sanding element, such as sandpaper, is supported on and covers the support surface of the sanding plate, and a clamping arrangement clamps the sanding element to the sanding plate. The clamping arrangement is mounted on the sanding plate for pivoting between an engaging and an disengaging position, and is biased toward the engaging position thereof. An actuating arrangement is mounted in a transverse wall of the casing for displacement between a retracted and an extended position and is operative for abutting against and displacing the clamping arrangement toward the disengaging position thereof during the movement of the actuating arrangement toward the extended position thereof. The actuating arrangement has an actuating portion which is accessible from the exterior of the casing, and a cam portion which engages an abutment surface of the clamping arrangement during the displacement of the actuating arrangement toward the extended position. The actuating arrangement may be arrested at least in the extended position thereof to thereby retain the clamping arrangement in the disengaged position during the exchange of the sanding element. Air may be withdrawn from the space bounded by the casing so as to remove dust resulting from the sanding operation from the vicinity of the sanding plate.
