A hand-held tool having an electromotive actuation is provided. The hand-held tool has a handle region and a working head. In the handle region, an actuating switch is provided, which is arranged for the application of manual force. The handle region including the actuating switch is sheathed with a flexible sheath part, which, starting from an end of the handle region that is facing away from the working head to beyond the handle region is formed without an opening. A sheath part for a hand-held tool is also provided.

A remotely controlled hand tool includes a grip region and an actuating button. A remotely controlled tool includes a holding region and a triggering means. The hand tool or tool enables favorable remote control by a removable application part held in the grip region or holding region. The hand tool or tool is attached to an automatically movable flying vehicle by means of an attachment.

A device head of a hydraulically actuatable tool includes an opposing holder which is integrally formed on the device head and which receives a first tool, and including a second tool that can be moved towards the opposing holder by a hydraulic piston. A cylindrical formation formed integrally with the device head and is provided relative to the hydraulic piston. The device head has an integrally formed toothing recess for the angular fixed, but also changeable, arrangement of a retaining rod.

A device is used to sever an electrical power cable for the transmission of high voltage. The device includes a frame having first movable cutting blade carried thereon and second stationary cutting blades carried thereon. The blades can sever the electrical power cable upon movement of the first cutting blade relative to the frame. A sensor is provided and is configured to register a position of the first cutting blade relative to the frame. An evaluation and/or transmission controller is configured to receive information from the sensor and interrupt severing of the electrical power cable by the blades in response to the information.

A tool configured to cut a workpiece includes a tool head which has a receiving contour in which the workpiece is received, and a movable cutting edge with a cutting contour. In the course of a cutting process, the cutting edge passes through the receiving contour. The cutting edge is subjected to the effect of an advancement part and can be moved to such an extent in the cutting direction(s) that it can pass all the way through the workpiece. In an embodiment, a position of the cutting edge reached after the cutting edge has passed all the way through the workpiece, the cutting edge, with removal from the advancement part, can be moved out from the cutting direction(s).

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.

Hand-held power tool

A hand-held tool that is prepared for remote control has a handle region, an actuating button, and a removable attachment part held in the handle region. The attachment part has a handling extension and a collar encompassing the handle region. The collar includes first and second collar parts pivotably connected together. The attachment part acts upon the actuating button. The actuating button is displaced into an actuating position by a housing section of the collar for a duration of an arrangement of the attachment part on the handle region.

A motor-operated shears which includes two blades that can move towards each other to perform a shearing movement is provided. In order to advantageously improve functional safety, towards the end of the movement, the blades are acted upon in a direction running transversely to the movement so as to keep the blades at a distance from one another in said direction.

The invention relates to a hydraulically actuated piston () guided in a cylinder (), and to a hydraulic working tool () having a working head (), wherein the piston () has an impact surface () which borders an impact space () on the piston side provided between the piston () and the cylinder (), and wherein hydraulic fluid () can act on the impact surface () by increasing the impact space () in order to move the piston () in an impact direction (r), and the piston () forms a limiting device () for a through-flow of the hydraulic fluid (). According to the invention, in order to design a hydraulic piston guided in a cylinder or a hydraulic working tool in such a way that no undue signs of wear occur even during working processes with the sudden disappearance of the counter pressure, a hydraulic chamber () filled with the hydraulic fluid () is formed in the impact direction (r) after the limiting device (), wherein a volume of the hydraulic chamber () is reduced according to the increase in the impact space (), by means of the displacement of hydraulic fluid () out of the hydraulic chamber () and into the impact space () via the limiting device ().
