Abstract:
A bit attaching arrangement for a power tool, the power tool having a rotatably driven shaft onto which a bit is attached and rotated therewith through the use of a collet, the arrangement comprising:a collet nut threadably engaging the shaft, said collet nut having one of a plurality of slots positioned on an outer peripheral wall;a first gear disposed on the shaft so that rotation of said first gear causes rotation of the shaft; andan actuating member having a second gear associated therewith and also having a slot engaging extension associated therewith;wherein said actuating member is positionable between a first position and a second position; in said first position said second gear engages said first gear and said extension engages one of said slots such that rotating of said actuating member results in rotation of the shaft while maintaining said collet at a generally fixed rotational location; in said second position, said first and second gears do not engage one another and said extension does not engage any of said slots such that the shaft can be freely rotated during operation of the power tool.
