Holding device for fitting head in placing arm

摘要

The holding device includes four elastic elements (8) which are connected together so that their long axes form a rectangle or square. Two of the elements which face each other are rigidly connected at the middle of their long axis to the placing arm via a fixing element (9).The other two elements are rigidly connected at their middle with the fitting head (11). The four elastic elements have a cross-section which has a maximum and a minimum surface moment of inertia in two orthogonal axes.
