摘要: An oscillating power tool includes a drive motor (M) producing rotary motion and an oscillating mechanism (30) for converting the motor rotary motion to an oscillatory side-to-side movement. The oscillating mechanism (30) includes a link (32) driven by an eccentric shaft (16) of the motor (M), a drive arm (40) that drives the hub (45) of the working tool (B) in oscillating motion, and a bearing arrangement (37) between the drive arm (40) and the link (32) that isolates relative rotation and translation between the components while still imparting an oscillatory motion to the drive arm (40).

摘要: A dust extraction system for a power tool having a output shaft, a collet configured for engaging a tool bit and a collet nut engageable to the output shaft, comprises a base configured for mounting on the power tool, the base defining a cavity having an opening for passage of the output shaft therethrough and a discharge chute in communication with the cavity. The system further includes an impeller sized and configured to be rotatably received within the cavity, including a hub and a plurality of vanes emanating from the hub configured to draw dust from the workpiece into the cavity and to direct the dust through the discharge chute. A collet nut is integrated into the hub of the impeller so that the impeller can be directly mounted to the output shaft of the power tool while clamping the collet onto the tool bit.
