Plate (1) has on the other side (3) a protrusion (4) with port (5), which is parallel to axis (6), furthermore the outer surfaces of plate (1) are covered with an elastic material layer (7) enabling thus (1), outside plate outline, to be an arm (8) connected firmly to the middle part (9) of axis (6).
