ABSTRACT:
A rapid releasable coupling for the tang of a work tool to a percussion apparatus. A tip of cylindrical shape extends the body of a percussion apparatus towards the front. Three longitudinal grooves are spaced an equal angle apart in the tip. A roller can move in each groove. Each roller has a pin with ends adapted to roll or slide on the edge of the groove. A ring threaded onto the tip and moveable longitudinally is returned rearward and against the rollers by a spring. The ring has section in the shape of a circular arc that partially surrounds the rollers. Displacement of the ring toward the front is by another ring which surrounds the assembly and which has an annular projection on its inner wall for holding the spring. A screw connection between the up and the other ring so that the other ring is moved longitudinally by being rotated.
