Abstract: The hand-held power tool has a tool socket, a motor and a pneumatic striking mechanism. The striking mechanism has an exciter driven by the motor along a working axis, a striker coupled to the exciter via an air cushion, and an intermediate striker arranged between the striker and the tool socket in the striking direction. The striking mechanism also has a guide in which the intermediate striker is guided. The guide has a first sliding surface that guides a first section of the intermediate striker, and a second sliding surface that is arranged offset relative to the first sliding surface in the striking direction and that guides a second section of the intermediate striker. A radial dimension of the first section of the intermediate striker is greater than a radial dimension of the second section of the intermediate striker.

Abstract: A shock absorbing protection structure for a handheld tool contains: a power tool, a shock absorption sleeve, and at least one stopper. The power tool includes a drive block which has a switch configured to turn on/off the drive block, the driving block also has a coupling tube which has a tool head fixed on the coupling tube away from the drive block, and the power tool includes a joining portion formed on the power tool. The shock absorption sleeve is fitted on the joining portion of the power tool, and between the shock absorption sleeve and the joining portion is defined an accommodation space. The at least one stopper is flexible and is defined between the shock absorption sleeve and the joining portion of the power tool, and the at least one stopper is located at the accommodation space so as to absorb vibration.

Abstract: The present invention relates to a impact body for a hydraulic impact device and, more specifically, to a impact body for a hydraulic impact device which is capable of remarkably reducing production costs by inserting a cylinder liner having a flow path into an inner wall of a body, adjusting an impact interval and an impact strength according to the properties of a material to be crushed by adjusting an impact distance of a piston, minimizing the loss of a fluid in a pipe by forming a cylindrical flow path between the body and the cylinder liner, and remarkably improving performance by employing a circular valve to shorten the flow path whereby reduction of pressure is minimized.

Abstract: A tool receptacle is disclosed. The tool receptacle has a receiving sleeve which has a prismatic or cylindrical cavity for receiving a tool and an elongated hole for receiving a locking body. The elongated hole has a closed edge formed of two opposing longitudinal sides at a constant distance and two end sides completing the elongated hole. An extension along the working axis of at least one of the end sides is less than half of the constant distance of the opposing longitudinal sides. A groove running parallel to the working axis is provided on an inner surface of the receptacle sleeve. The groove is disposed in an extending manner at the elongated hole on the inner surface along the working axis.

Abstract: A handheld machine tool is disclosed. The tool has a tool receiving area and a striking mechanism. The striking mechanism contains a striker, an exciter, and a pneumatic chamber. The striker strikes an intermediate striker at the strike point. The exciter is driven between a first dead center at a distance from the strike point and a second dead center in the vicinity of the strike point. A housing, which is encapsulated in an air-tight manner, has an interior which is closed by an exciter end face facing away from the striker. The interior is connected to the pneumatic chamber by a first valve which can be closed by the striker and by a second valve which can be closed by the exciter. The first valve is arranged in the vicinity of the strike point and the second valve is arranged in the vicinity of the first dead center.
