<p>The tool i.e. drill hammer, has a damping device (9) formed with first, second and third elastic braces (12-14) in star-shape and coupling a handle (6) with a tool housing (2). The second- and third elastic braces are connected with the tool housing, and the first elastic brace is connected with the handle. Connection regions of the second- and third elastic braces rest on both sides of a symmetry plane of the tool housing, respectively. The second- and third elastic braces are arranged perpendicular to the first elastic brace, and the damping device is symmetrical to the first elastic brace.</p> |
