Abstract
A powered hammer includes a body in which is disposed a motor and a hammer mechanism driven by the motor when the motor is activated. A tool holder is coupled to a front portion of the body and which is capable of holding a cutting tool. The hammer mechanism, when driven by the motor, is capable of imparting impacts to a cutting tool, when held by the tool holder. A handle is moveably coupled to a rear portion of the body for movement toward and away from the body along a tool axis of the tool holder. The handle includes a grip portion and first and second end connection sections coupled to opposite end portions of the grip portion. The first and second end connection sections are slideably mounted on first and second arms that project rearward from the body. A movement control mechanism is mounted inside the handle and coupled to the first and second arms and the handle. The movement control mechanism is configured to ensure that the two end connection sections move toward and away from the body in unison to inhibit angular movement of the grip portion relative to the body. A damping element disposed between the handle and the body to reduce vibration transferred from the body to …
