<p>The handle (10) of the tool has a hollow box-shaped front (11) for the accommodation of the lower segment (131) of a holding element (13). A tool head (2) of the appropriate design can be attached to the holding element (13) moving inside the space (11) at the front of the handle (10). When a spring supported pin (14) guided transversally through the tool front (11) and an elliptical hole (132) in the lower segment (131) of the holding element (13) is pressed complementary toothed areas (134,151) at the segment (131) and on top of an axially positioned pin (15) engage or are released.</p> |
