A hydraulically activatable working device includes a hydraulic cylinder and at least one first and one second partial piston provided therein. The partial pistons can be moved under pressurization by a hydraulic medium to perform a working operation. Each partial piston has an impact surface at its lower end against which the hydraulic medium may act. A piston rod is coupled to the hydraulic cylinder and has an impact surface at its lower end against which the partial pistons may act. The impact surface forms a first partial impact surface against which the first partial piston acts, and forms a second partial impact surface against which the second partial piston acts. The first and second partial impact surfaces do not overlap each other in direction across to the traversing direction.

The invention relates first to a device for applying a pressing force, comprising two pressing jaws () which can be moved linearly relative to each other via a hydraulic piston-cylinder assembly (). Additionally, an actuation cone () is provided for an expanding device (), said cone carrying out a forward and rearward movement depending on an actuation of the hydraulic piston-cylinder assembly (). In order to advantageously develop the device, the actuation cone () is connected to the hydraulic piston () of the hydraulic piston-cylinder assembly () for the forward and rearward movement. The invention further relates to a device for applying a pressing force, comprising two pressing jaws which can be moved linearly relative to each other and which can be held in receiving areas and to a pair of pressing jaws.

A method of operating a hydraulically or electric motor operated tool includes providing a device shaft having electrical contacts; providing an accumulator having an adapter comprising a wall thereon; latching the adapter to the device shaft by a latching part; and engaging a tool with the latching part thereby detaching the adapter from the device shaft, whereupon during engagement of the tool with the latching part, the wall of the adapter is destroyed. When the device shaft and adapter are engaged, walls of the device shaft and adapter form an internal cavity and the latching part is positioned entirely therewithin such that the latching part is completely hidden from view. A hydraulically or electric motor operated tool is also disclosed.
