The tool has needle chisels (4) in a cage (7), charged by a striker (3), which is loaded by a pressure spring (5). The spring is retained under pretension between shoulders (28,29) of an assembly sleeve (27). Spring, assembly sleeve, and a stop sleeve (6) on the striker, form a modular unit. The assembly sleeve is displaceable within a guide tube (2b) for the striker. When the stop sleeve is charged by the striker via the spring and the shoulder, the assembly sleeve supports itself on a stop body (9). |
