Clamping device for toolless clamping of a saw blade

A clamping device for toolless clamping of saw blades equipped with a clamping shank for a hand machine tool, said clamping device comprising two clamping parts that are pressable against each other, each of said clamping parts being provided with a support surface for the clamping shank of a saw blade insertable between said clamping parts, at least one of said clamping parts being movable in relation to the other of said clamping parts in order to clamp and release the clamping shank;

• and an independent actuating element that is movable by hand and provides a movement of said at least one clamping part, wherein said at least one clamping part is a tool clamp attachable to a drive element of the hand machine tool, while the other of said clamping parts is a pressed part that is mounted in said tool clamp in a relatively movable fashion and is connected via a coupling element to said actuating element;
• wherein said coupling element is a sliding sleeve accommodated on said tool clamp in an axially sliding fashion, said sliding sleeve having a sleeve wall which is provided with at least two diametrically opposed guide slots extending at an angle of inclination to a longitudinal axis of said sliding sleeve, into which diametrically opposed guide pins, projecting from said pressed part protrude;
• and wherein said actuating element is a rotating sleeve, that encompasses said sliding sleeve, and is attached to said sliding sleeve by a screw thread.
