Sealing tool for driving e.g. nail, has return device with damping unit to dampen vibrations of lever whose rear side contacts with bearing surface of damping unit, where bearing surface has contour related to contour of rear side

摘要

The tool has a return device (30) with a lever (31) for moving a pusher-piston (15) from an end position to an initial position. The device has a damping unit (44) to dampen vibrations of the lever during an impact of the lever on a support portion. The lever has a rear side (36) contacting with a bearing surface (46) of the damping unit. The bearing surface has a contour corresponding to a contour of the rear side of the lever.
