ABSTRACT:
The present invention is a collet assembly with a sliding lock. The assembly includes a segmented tubular body with the segments being increasing in size from one end of the body to the other. The two smallest segments form a plug for securing the collet assembly to a first object. The two larger segments form a collet which receives a second object. The collet has a tapered cross-sectional area, with the area decreasing from the end of the collet assembly towards the middle of the collet assembly. The collet includes longitudinal slots that extend from the end towards the middle of the collet assembly. The collet may include a sleeve in its bore. Like the collet, the sleeve has a plurality of longitudinal slots. The collet assembly also includes a slidable tubular collet lock having a passageway for receiving said collet therethrough. The passageway is also tapered with a first cross-sectional area at one end tapering to a smaller second cross-sectional area at its other end approximate the middle of the collet assembly. The taper of collet lock is less than the collet. By moving the collet lock over the collet, the collet and sleeve are compressed due to the camming action between the collet and collet lock thus holding the second object therein.
