    • 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.

    • An oscillating drive for a power tool includes a wobble shaft located on a drive shaft of a motor for a power tool, and a wobble member rotatably supported on the wobble shaft. The wobble member includes a wobble drive structure that defines a drive axis. A tool driver includes a tool drive structure at one end that is coupled to the wobble drive structure and a tool holder configured to releasably retain an accessory tool. Rotation of the drive shaft causes the wobble shaft to wobble about an axis of the drive shaft. The tool driver holds the wobble member against the rotation of the wobble shaft such that the wobble member wobbles without rotating which results in an oscillating motion of the drive axis of the wobble member in a plane that is parallel to the axis of the drive shaft. The oscillating motion of the drive axis causes the tool driver to oscillate.
    • 用于动力工具的摆动驱动器包括位于用于电动工具的电动机的驱动轴上的摆动轴和可旋转地支撑在摆动轴上的摆动构件。 摆动构件包括限定驱动轴的摆动驱动结构。 刀具驱动器包括一端的工具驱动结构,其联结到摆动驱动结构,以及被配置为可释放地保持附件工具的刀架。 驱动轴的旋转使摇摆轴绕驱动轴的轴线摆动。 工具驱动器保持摆动构件抵抗摆动轴的旋转,使得摆动构件摆动而不旋转,这导致摆动构件的驱动轴线在平行于驱动轴的轴线的平面内的摆动运动。 驱动轴的摆动运动导致刀具驱动器振荡。
