Power tool handle, e.g. for a hammer drill, has a parallel lever linkage for mounting at the tool housing together with a damper spring to dampen vibrations at the handle when using the tool

摘要

The handle for a power tool is coupled to the tool housing (1) with a damper spring (12). The handle (2) is linked to the tool housing through two or more parallel levers (4,5), at right angles to the longitudinal tool axis (3), mounted to the tool housing at one end and the handle at the other end. The handle linkage points (6,7) are away as far as possible from the housing linkage points (8,9).
