A damping return hammer includes a grip handle, a first elastic damping arm, a second elastic damping arm, and a hammer head provided at the fronts of the first elastic damping arm and the second elastic damping arm, respectively. The front ends of the first elastic damping arm and the second elastic damping arm are upper and lower respectively, and extend at a certain distance forward and are in the same longitudinal section. The two hammer heads are provided at the front ends of the first elastic damping arm and the second elastic damping arm respectively. A gap is between the two hammer heads and is fitted therein with a rubber energy-storage cushion block.

The sealing device includes an inner sealing ring including an annular inner sealing portion provided with a sealing lip intended to cooperate in a sealed manner with the outer surface of a striking piston of a hydraulic percussion apparatus, and an outer sealing element mounted around the inner sealing portion and intended to bear in a sealed manner at the bottom of an annular housing arranged on a guide body of the hydraulic percussion apparatus. The inner sealing ring further includes an annular protective portion axially shifted relative to the inner sealing portion and internally delimited by at least one converging protective surface, annular and converging towards the sealing lip, and an annular groove opening into the inside the inner sealing ring, the annular groove being disposed between the sealing lip and the converging protective surface.

A technique for making a handle vibration-proof while avoiding size increase is provided in an impact tool. The impact tool has a striking mechanism part for driving a tool bit in its axial direction, a motor for driving the striking mechanism part, a tool body housing the motor and striking mechanism part, an outer shell housing covering part of the tool body, a handle that is integrally formed with the outer shell housing and extends transversely to the axial direction, a first handle end portion formed on one extending end of the handle, a second handle end portion formed on the other extending end of the handle, a first elastic element that connects the first handle end portion and tool body for relative movement in the axial direction, and a second elastic element that connects the second handle end portion and tool body for relative movement in the axial direction.

To provide a handle that is effective at achieving both vibration resistance and usability. A handle attached to a tool body of a power tool has: a grip portion; a connecting portion that connects to the tool body; elastic element interposing regions that are formed between the grip portion and the connecting portion; elastic elements disposed in the elastic element interposing regions; a powder filling region formed between the grip portion and connecting portion; and a plurality of powder bodies that fill the powder filling region.

It is an object of the invention to provide an impact tool having a rational mechanism in an idling state. According to the representative invention, in an idling state defined as a state in which a tool accessory 119 is not pressed against a workpiece and an impact bolt 145 transmits a striking force to the tool accessory 119, the tool accessory retainer 510 moves with respect to a tool accessory holder 117 by movement of the tool accessory 119 in the longitudinal direction, so that the striking force is cushioned.

A hand-held power tool includes a tool receiving area which has an inner receiving area that is designed to receive an insert tool and also includes a striking mechanism for applying striking pulses to the insert tool. A locking bolt is provided in order to lock the insert tool, wherein the locking bolt is connected to an operating element which is designed to position the locking bolt such that the insert tool is locked in a locked position and is unlocked in an unlocked position in order to be removed from the inner receiving area, and the locking bolt is paired with at least one damping element for at least partly damping a force acting on the insert tool in an idle running state of the hand-held power tool. The tool receiving area is paired with a receiving chamber in which the locking bolt and the at least one damping element are arranged. The locking bolt is at least partly received in a receiving area of a force transmission element, and the at least one damping element is arranged directly on the force transmission element in the receiving chamber.

A rubber mallet includes a handle and a striking head. The striking head includes an outer body and an inner body within the outer body. The outer body defines a receiving space receiving the inner body. The outer and inner bodies are made of different materials.

A vibration damping handle assembly is disclosed which has a control handle having an indentation formed therein, an insert adapted for fitting into the indentation formed in the control handle, an adapter sleeve having an exterior surface and an interior surface having an indentation formed in the interior surface with the indentation adapted for receiving the insert fitted into the indentation formed in the control handle, and an outer sleeve member for fitting on the exterior surface of the adapter sleeve.

A power tool having a hammer mechanism includes a tool body defining the driving axis, a motor housed in the tool body, an elongate handle connected to the tool body in a cantilever manner and extending in a direction intersecting the driving axis, and at least one biasing member disposed between the tool body and the handle. The motor has a motor shaft that is rotatable around an axis parallel to the driving axis. The handle includes a first end portion connected to the tool body to be pivotable around a pivot axis relative to the tool body, a free end, and a grip part disposed between the first end portion and a free end of the handle. The at least one biasing member is configured to pivotally bias the tool body and the handle such that the grip part and the tool body move away from each other.

Hammer drill and/or chipping hammer having a drive motor, an impact mechanism and a tool fitting for fitting a tool, wherein the impact mechanism has an anvil that is axially displaceable in an anvil guide and acts on the tool, wherein the impact mechanism has an idle-strike damper element and a rebound-strike damper element, which are formed in one piece with one another and as such form a combined damper element, wherein the anvil guide is arranged outside, preferably only outside the combined damper element.
