Beschreibung
Zusammenfassung:	The invention provides a power tool having an impact mechanism, which includes a rotary shaft defining a tool axis of rotation, an impact member moveable along the tool axis of rotation, a support member fixed in position relative to the tool axis of rotation, a biasing member for urging the impact member away from the support member, and at least one axial stop member positioned between the impact member and the support member. According to the invention, the distance between the axial stop member and the tool axis of rotation is more than the distance between the biasing member and the tool axis of rotation.
