Abstract
A chucking device for holding a dental tool by a collet chuck with collet chuck sleeve, wherein the collet chuck can be released by a push button against the force of clamping spring. The collet chuck sleeve has at both ends thereof axial slots, so that it is constructed at both ends as a collet chuck. The casing of the collet chuck is undercut at both ends, wherein the undercut at the side of the tool is mounted in an axially fixed, but rotating conical seat and the undercut on the side of the push button is mounted in a conical seat of an actuating member. The actuating member is under the influence of the clamping spring and, for releasing the collet chuck, the actuating member is displaceable against the force of the clamping spring toward the axially fixed seat. Instead of the collet chuck, it is also possible to provide two axially spaced apart groups of radially displaceable clamping elements.
