A working tool has a working head and a body device. In an embodiment, an electric motor having a drive shaft with a longitudinal axis, and a transmission are connected to each other and are in the body device. In an embodiment, the working head is a hydraulic cylinder with a hydraulic piston that can be moved between extended and retracted positions in a direction of travel. A hydraulic medium pump and a drive for the hydraulic medium are provided in the body device. In an embodiment, the transmission is connected to the electric motor so as to be movable in the direction of the longitudinal axis in such a way that it is limited by a limit stop. In an embodiment, the hydraulic cylinder is attached to the body device so as to be movable in the direction of travel that it is limited by a limit stop.
A working tool with a working head and a body device, wherein an electric motor and a transmission, which are connected to one another, are arranged in the body device, and wherein the electric motor additionally comprises a driveshaft drive shaft with a longitudinal axis and the transmission is connected to the electric motor so as to be movable in the direction of the longitudinal axis in such a way that its motion is limited by a limit stop, comprising a housing bottom of a housing of the transmission abuts in an unaffected home position on a ceiling of a housing of the electric motor in such a way that its motion is limited by a limit stop, and in that a drive shaft of the electric motor extends through the ceiling, as well as the bottom, in order to engage into the transmission region.
A hydraulic working tool with a working head and a body device, wherein the working head comprises a hydraulic cylinder with a hydraulic piston, which can be displaced between a retracted position and an extended position in a direction of travel, and wherein a hydraulic medium pump and a drive for the hydraulic medium pump are additionally provided in the body device, comprising:
