摘要： A hand-held power tool includes a pneumatic percussion mechanism (20) having a driving member (22) reciprocating in the guide tube (21), a percussion member (23) driven by the driving member (22), and an air spring (24) located between the driving member (22) and the percussion member (23) for transmitting a reciprocating movement of the driving member (22) to the percussion member (23), and a motor-driven elongate swashplate member (29) for reciprocating the driving member (22) a displacement stroke of which is adjusted by an adjusting member (31) displaceable along a longitudinal extent of a swashplate member (29) for steplessly adjusting a swashplate angle that determines the displacement stroke of the driving member (22).
