Definitions

  • the invention relates to an assembly for a housing part of a hand-held tool and a housing part for a hand-held tool.
  • Hand-operated tools which comprise a housing, a drive motor arranged in the housing and a tool driven by the drive motor.
  • Corresponding implements have several operating elements such as an actuating lever, a locking lever, etc.
  • additional controls such as a speed lever, etc. on the tool.
  • a disadvantage of such working devices is that when there are several operating elements, an ergonomic arrangement of such is only possible with difficulty.
  • the invention is based on the object of specifying an assembly that enables an ergonomic arrangement of operating elements on a working device while at the same time facilitating the assembly of the working device.
  • the invention is based on the object of specifying a housing part that enables an ergonomic arrangement of operating elements on a working device with simple assembly of the working device at the same time.
  • the idea of the invention is based, inter alia, on the finding that a plurality of operating levers can be arranged ergonomically relative to one another, in particular if they have pivot axes which are aligned differently from one another.
  • the actuating lever is usually actuated using the index finger of the operator.
  • the actuating lever has a pivot axis which is aligned in the direction in which the housing is removed from the mold.
