Abstract
A power tool includes a power head receiving power from a power source. A drive coupled to the power head extends along a longitudinal axis, and the drive is engaged with a connector. Various aspects relate to the connector. The connector includes an internal bore configured to couple to the drive to a shank of a working tool. The connector further includes an external lobe protruding radially outward from the longitudinal axis, the lobe having a locking mechanism configured to secure the second working tool in response to relative movement between the lobe and the second working tool in both an axial direction and a rotational direction.
Claims20
A power scrubber for use with a brush having a shoulder and a brush bayonet coupling, the power scrubber comprising:
- a power head receiving power from a power source;
- and
- a drive coupled to and driven by the power head, the drive extending along a longitudinal axis, the drive including a connector for selectively engaging the brush, the connector including,
- an external lobe protruding radially outwardly from the longitudinal axis, the external lobe configured to press upon the shoulder to transmit torque from the drive to the brush, and
- a drive bayonet coupling angled positioned on the external lobe, the drive bayonet coupling being configured to releasably lock the connector with the brush bayonet coupling;
- wherein the drive bayonet coupling engages the brush bayonet coupling in response to relative movement between the external lobe and the brush in both an axial direction and a rotational direction about the longitudinal axis when the external lobe is within the brush.
