US 6,059,493 A · Manual machine tool with tool holder and appropriate tool

Abstract

The hand-held machine tool has a tool holder (20) provided with a receptacle (19) into which a shaft portion (15) of a tool (16) is axially insertable. The tool holder (20) has a longitudinal axis (11) and includes a guide device (18) for axially guiding the tool (16); a device (23) for rotary slaving of the tool (16); a retaining device (28) for axially securing the tool (16) and a locking member (34) for locking the retaining device (28) in an open configuration for insertion or removal of the tool (16). The retaining device (28) is located in front of the guide device in an insertion direction of the tool (16) in the tool holder (16). The retaining device (28) is provided with an opening (31) for passage of the tool (16) through it. The retaining device (28) includes a clamping part (30) having an open position arranged approximately perpendicular to the longitudinal axis (11) and is pivotable out of the open position in a direction toward the longitudinal axis (11) to reduce an effective cross-section of the opening (31) and into a clamping position in which the clamping part (30) and the tool (16) are clamped together.
