Abstract
A coupling device for connecting tools with different configuration to a driving mechanism. The coupling device may have a longitudinal axis, a first clamping device which may engage a tool with a peg-shaped clamping segment and a second clamping device which may engage a tool with a generally flat portion. The coupling device may be used to connect a tool to a drive shaft which may be attached to a motor. The tools may be locked or unlocked relative to the coupling device by sliding a sleeve along the axis of the coupling device. The sleeve may be biased in a locked position by biasing means such as a spring. The coupling device may be configured so that the first and second tool may be prevented from rotating and/or moving axially with respect to the drive shaft.
