20120289901 | APPARATUS FOR ESTABLISHING THE PENETRATION DEPTH OF A TUBULAR OR ROD-SHAPED SLIDING PART IN AN ACCOMMODATION PART AND MEDICAL HANDPIECE USING SUCH APPARATUSES - A device for establishing the penetration depth of a tubular or rod-shaped sliding part in a receiving part and to a medical handpiece using such devices. There is an adjusting element that surrounds the sliding part and which can be adjusted in the longitudinal direction of the sliding part and can be blocked in the particular position by a clamping device to establish the penetration depth of the sliding part in the receiving part. The clamping device is formed by a rocker element that is arranged between the adjusting element and the sliding part. The rocker element can be moved between a first rotational position, which allows the adjusting element to be slid in the longitudinal direction of the sliding part, and a second rotational position, which blocks the adjusting element from being slid, by rotating the adjusting element transversely to the longitudinal direction of the sliding part. | 11-15-2012 |
