| 摘要 |
This invention relates to a marking device for making two-dimensional identification signs on the surface of any object, of the type in which the micro-percussion tool is borne axially by a slewable rod which is retained angularly along its axis and which penetrates in a fixed housing through a Universal joint allowing free orientation thereof in all directions along an axis of symmetry, characterized in that orientation of the rod is controlled with the aid of two independent motors which act on one and the other, respectively, of the two orthogonal pivot pins of the joint.
