Abstract (en)
[origin: WO03098001A1] The invention relates to a fixing device for a shank chisel, comprising a base part (20) and an upper part (30), the upper part being detachably connected to the base part. According to the invention, the upper part (30) has an opening (30.4) for receiving a shank chisel and the base part (20) has a shaft opening (22), into which a shaft (30.11) of the upper part is inserted, said shaft having a tensioning surface (30) that rests against the counter surface (40.1) of a clamping element (40). The latter comprises a tensioning screw (50), which is used to clamp the tensioning surface against the counter surface. The base part (20) has a shoulder surface (24), which is located in the vicinity of the shank opening (30.4) and at least partially surrounds the latter, a stop surface (25) adjoining the rear region of the shoulder surface (24) in the infeed direction at an angle. The upper part (30) rests on the stop surface (25) by means of a supporting surface (30.8) and is held at a distance, at least in sections, from the base part (20).
