发明名称 NOISE DAMPED CHISEL HAMMER
摘要 A hand-held power tool, particularly a chipping tool has an impact-damping arrangement for damping axial impacts of a striking member against a working tool. The arrangement includes a shaped member which is firmly and axially movably held on an outwardly extending portion of the tool and constituted by an elastic material. The shaped member has a substantially radial abutment face which abuts against a face of a tool holder in striking and noise-damping manner and radially overlaps an opening of a receiving recess of the tool holder so as to serve simultaneously for protection from dust.
