Abstract

A power tool with an impact mechanism in particular, an impact wrench or a hammer drill, comprising an outer housing and an inner housing at least partly surrounded by the outer housing; an motor installed in the inner housing, and an impact mechanism connected to the motor and fixedly mounted to the inner housing, to define an integrated inner sub-assembly comprising the motor and the impact mechanism; the inner housing and outer housing are elastically connected to each other in axial direction by at least two elastic elements pre-tensioned against each other, the inner housing floating received in the outer housing in axial direction, thereby reducing the vibration suffered by the user from the impact mechanism and motor of the power tool.
