摘要： An impact tool includes a tool-accessory holding part, a body and a first hammering member. The tool-accessory holding part has a through hole extending in a hammering-axis direction and is configured to hold the tool accessory inserted into the through hole to be movable in the hammering-axis direction. The body is connected to the tool-accessory holding part in the hammering-axis direction and has an internal space communicating with the through hole. The first hammering member is linearly movable in the hammering-axis direction and configured to drive the tool accessory in the hammering-axis direction by colliding with the tool accessory. The tool-accessory holding part and the body are connected in the hammering-axis direction via a first elastic element to be movable relative to each other. A second elastic element is interposed between the first hammering member and the body in a radial direction with respect to the hammering axis.

摘要： A portable power tool is disclosed. The tool has a tool holder in which a tool can be moveably inserted on a working axis in a striking direction. A percussion mechanism has a striker coupled via a pneumatic chamber to an exciter moved periodically along the working axis and an intermediate striker arranged in the striking direction downstream from striker. The intermediate striker is guided in a slide bearing with a tolerance coaxially to the working axis. The intermediate striker has a ring-shaped bead. A hollow-cylindrical backstop is arranged in the striking direction upstream from the bead. The backstop is moveably guided on a sliding surface with radial play along working axis. The radial play is at least three times as large as a tolerance of the guide of the intermediate striker in the slide bearing.

摘要： A bumper of a driving tool has a cylindrical overall shape and also has a space portion expanding downward therein. The bumper is provided with an upper portion, an intermediate portion, and a lower portion. A normal inclined-surface, in which an outer diameter becomes larger from an upper end of a full height of the bumper toward a slightly upper position of the intermediate portion, is formed at a periphery of the upper portion. A bulging-out portion haying the largest outer diameter in the bumper is bulged out, at a periphery of the intermediate portion. A reverse inclined-surface, in which the outer diameter becomes smaller toward downward, is formed at the periphery of the lower portion.

摘要： A power tool includes a grip, a connecting part, an elastic element, an electrical switch and an operating member. The connecting part connects the grip to the power tool body. The elastic element is disposed between the connecting part and the power tool body. The operating member is switched by a user between an energizing position and a de-energizing position. The operating member is retained in the position to which it is switched. The operating member is disposed in the connecting part in such a manner as to be slidable in a direction transverse to the longitudinal direction of the power tool body and to the extending direction of the grip.

摘要： A resilient stop assembly for an impact tool includes first and second resiliently deformable parts, and a substantially rigid part situated between the deformable parts. Each of the first and second resiliently deformable parts and the substantially rigid part comprises: first and second opposite impact surfaces, at least one peripheral surface joining the impact surfaces, and an aperture extending entirely through the part between exit openings in the impact surfaces. The first impact surface of the second resiliently deformable part is separated from the second impact surface of the first resiliently deformable part by contact of those first and second impact surfaces with the substantially rigid part.

摘要： It is an object of the invention to reduce noise caused by run-out of a tool bit in an impact tool. The representative impact tool according to the invention includes a tool holder 137 that houses a tool bit 119 in such a manner that the tool bit can linearly move in its axial direction, and a barrel 108 that is integrally connected to the tool holder 137 The impact tool further includes an elastic element 155 that is disposed between an inner circumferential surface of the tool holder 137 and an outer circumferential surface of the tool bit 119 in an end region of the tool bit 119 on the barrel side and connected in close contact with the tool holder 137 and the tool bit 119 over a predetermined length of the tool bit 119 in the axial direction. The elastic element 155 applies a biasing force to prevent a run-out of the tool bit 119 in a direction transverse to the axial direction. Further, an intermediate element 145 comes in point contact with the tool bit 119 on its axial center line.

摘要： There is provided an improved abrasion-resistant hydraulic hammer with a low noise level for preventing the leak-out of the noise made inside. The object is to provide an abrasion-resistant hydraulic hammer with a low noise level which can contribute to the establishment of a comfortable working environment and meet environmental standards against noise pollution by reducing leaked-out crashing sound. To achieve the object, a cylindrical plastic member containing oil is installed to a hole formed outward under a piston installed inside the hydraulic hammer, for guiding a tool in contact with the circumferential surface thereof.
