Abstract
A clamping device for clamping an accessory to a power tool includes a first flange, a spindle member, and a cam member. The first flange is coupled to a drive system of the power tool and is configured to receive the accessory. The spindle member defines a longitudinal axis and includes a second flange provided on an end of the spindle member and a follower member provided on an opposite end of the spindle member. The cam member includes a cam surface configured to interact with the follower surface, the cam member is rotatable about the longitudinal axis to a clamped position and to an unclamped position. In the unclamped position the accessory is removable from the first flange, and in the clamped position the accessory is clamped between the first flange and the second flange.
