ABSTRACT OF THE DISCLOSURE The percussion mechanism of this device , comprising a cylinder, a free piston, an anvil, a tool holder in which a bundle of needles is disposed, the heads of which are applied to the anvil, is mounted to slide in a tubular housing between two springs used to insulate dynamically the percussion mechanism of the housing and of the handle which holds it. The cylinder is mounted in the housing by a suspension comprising two annular seals and the cylinder is set with a clearance so that the cen- tering provided by the seals insulates mechanically the cylinder of the housing and reduces the transmission of vibrations.
