摘要
The shaft (3) of the tool accommodated inside the holding area (1) has a wider section (19) at the front followed by two longitudinal curved recesses (11, 12) opposite each other serving as path for the ball-shaped locking device (5) in combination with corresponding areas (20, 21) located at the inner surface of the holding area (1) and has a smaller diameter at its rear end (18). The locking device (5) can be released by axially moving a spring (9) supported sleeve (8) which is automatically pushed back by a second spring.
