ABSTRACT:
A tool support for a hand tool machine includes a housing surrounding a drive spindle having a recess to receive a tool-receiving sleeve. This recess accommodates a compression spring which biases an end portion of the sleeve. The sleeve is also provided with a tool-facing portion receiving a tool to be used and an intermediate shaped portion which is arranged for a possible slidable movement within an adapter rigidly mounted to the drive spindle. A second sleeve is provided in the tool support which is threadably mounted on the tool-facing portion of the tool-receiving sleeve and is arranged so that its axial position may be adjusted. Said end portion of the sleeve has such a length that the length of contact of this end portion with the recess should be relatively larger than the combined length of contact of the shaped portion of the tool-receiving sleeve with the inner surface of the adapter and a possible path of the second sleeve in the axial direction. Such a structure provides a quick change of a tool to be used without any potential danger to an operator.
