发明名称 HAND-HELD POWER TOOL, PARTICULARLY A DRILLING AND/OR CHISEL HAMMER, HAVING A DAMPER UNIT
摘要 The invention relates to a hand-held power tool, particularly an impact wrench, a percussion drill or a drilling hammer, having a drive and/or output (12, 13, 14, 112, 113, 114) comprising at least one line of action (34, 134), which at least generates oscillations along the line of action (34, 134). In order to reduce said oscillations, the hand-held power tool is equipped with at least one damper unit (140). The damper unit (140) comprises at least one movable damper element (144) having at least one degree of freedom. For this purpose said degree of freedom forms an angle W1 that is different from zero with the line of action (34, 134).
