Abstract

The handheld power tool has a tool socket to hold a chiseling tool on a working axis and a striking mechanism that acts upon the tool in the striking direction. The striking mechanism is arranged in a machine housing. A handle is oriented along a handle axis that is perpendicular to the working axis and that is installed on the machine housing by three suspension assemblies. The second suspension assembly has a lever arm that runs along the handle axis. The first end of the lever arm is attached to a machine housing and to a handle. A guide is attached to the other machine housing and handle. The second end of the lever arm in the guide can be forcibly deflected against a spring along a trajectory that is slanted or perpendicular to the working axis.
