A hammer mechanism is described as having a snap die, a tool chuck drive shaft, and an impact generating shutoff unit, which has a blocking element, which is provided for the purpose of preventing an axial displacement of the snap die. The blocking element acts on the snap die in parallel to at least one force of the tool chuck drive shaft, at least during a drilling operation.
