Abstract (en)

A vibration-dampened holder for a chiselling tool comprises a gripping sleeve (10) which telescopically displaceably surrounds a shaft (20) which is detachably connectable to a tool (70), two helical springs oriented in the longitudinal direction of the rod and surrounding the rod, being connected by one end to the sleeve (10). The two springs (31, 32) are connected to the shaft (20) approximately mid-way along the length of the sleeve (10), and are pre-stressed with a force of about 7 kg, as well as having different spring constants. The sleeve (10) is secured against turning in relation to the shaft (20), and the rear spring (31) is arranged to be compressed approximately 150 mm from the unloaded state of the holder, upon an axial load of approximately 40 kg. <IMAGE>
