Abstract
A lock rod is provided extending along and reciprocally movable along an axis Y--Y and having a cylindrical cross section near one end. Two circumferentially spaced depressions are located in the cylindrical surface for receiving locking elements in an unlocked position. Extending from the first depression is a ramp inclined with respect to axis Y--Y and from the second depression is a groove parallel to axis Y--Y for driving locking elements radially outwardly to abut against a toolholder shank to lock it onto a tool support member.
