Quick joining and -release chucks, operated with spring supported ball, engaging with recess at shaft of tool

摘要

For insertion the upper end of the tool shaft is pressed against the release element (10) acting on a spring (9) and causing a ball (12) to move to the bottom of a recess (17) at the release element (10). A tensioning ring (13) is moved into a locked position simultaneously to a second, a locking ball (19) engaging with a recess located at the shaft. When the tensioning ring (13) is moved into the opposite direction against the forces of the spring (14), the locking ball (19) is moved into a deeper recess (21), facilitating the release of the release element (10) by moving the first ball (12).
