ABSTRACT:
A device for clamping and unclamping dental tools as, for example, drills, in a dental handpiece with an angled head in which the tool is held by means of a two-part clamping unit. One part of this clamping unit has a collet for holding the tool, and the other part of the clamping unit has a driven rotary hollow shaft located in the head. The collet is movable lengthwise inside the hollow shaft. To assume its clamped or unclamped position, the collet and hollow shaft are threadable into one another. One of the two parts of the clamping unit has at least one key surface accessible from the exterior at the tool end of the head. The other part of the clamping unit has also at least one key surface accessible from the exterior. A U-shaped carrier is provided with a first flange having a stationary key with parts for engagement with the key surfaces located at the tool end of the head. The other flange of the carrier has a pin-shaped key projecting into the area between the two flanges and axially movable in a hollow space of an exterior attachment of this other flange against the action of a spring in the direction away from the first flange. The pin-shaped key can be rotated manually by means of a knob on the key and projecting from the attachment. The pin-shaped key has a handle mounted on the U-shaped carrier and is actuatable by finger pressure applied transversely to the longitudinal axis of the key to axially move the key against the action of the spring.
