Abstract (en)
[origin: EP0280195A2] A percussion apparatus comprises a vertically extending tubular housing (2), an end cap (28) removably mounted to the lower end of the housing, and a tool holder (34) extending through the end cap as elastically supported thereby and slidably movable axially of the housing. A chisel (18) extends through the holder and has a head located within the housing to be hit by a hammer rod (13) axially reciprocated in the housing. A tool holding device (37) is mounted on the holder outside the end cap for selecting a first condition in which the chisel is prevented from falling off the holder while being allowed to move axially within a limited range, and a second condition in which the chisel is allowed to be completely removed from the holder.
