Abstract
A clamping device for fixing a wheelchair drive unit to a wheelchair frame, the clamping device comprising a lever, a first clamping jaw, a second clamping jaw, which are movably mounted on a clamping jaw holder via a jaw path between an open position and a closed position. The lever is movably coupled to the first clamping jaw and the second clamping jaw via a lever path such that a movement of the lever along the lever path causes the clamping jaws to move along the jaw path. A transmission arrangement couples the lever to the first clamping jaw and the second clamping jaw in such a way that, moving the lever by half the lever path causes the first clamping jaw and the second clamping jaw to move by more than half the jaw path in the direction of the closed position of the clamping jaws.
