    • A power hand tool body has a barrel with a depending skirt portion from which depends an elongated handle. Elongated grooves are formed in opposite sides of the skirt portion and extend between forward and rearward ends thereof, the grooves being part-cylindrical in transverse cross-section and having rectangular cross-section neck portions opening at the sides of the skirt. A hollow tubular grip formed of flexible and resiliently stretchable material has an end portion with part-cylindrical attachment members extending laterally and inwardly from opposite sides thereof so that, when the grip is slipped over the handle, the end portion may be stretched to insert the attachment members respectively into ends of the grooves for retaining the grip in place.

    • A battery-powered driver tool has a tool housing with a socket-type coupler which receives a plug-type coupler of a battery pack in any of four different rotational orientations. Four keys on the battery pack are received in four keyways on the tool housing for non-rotatable engagement, the parts being retained by a split snap ring on the battery pack which cams past four cam shoulders on the tool housing, so that the parts automatically snap-engage and disengage in response to a simple push-pull motion. The battery pack includes a plurality of battery cells connected in series between positive and negative terminals which are designed to respectively engage positive and negative terminals on the tool housing in any of the four rotational orientations of the battery pack. The battery pack has a flat base surface, the parts being designed so that the tool/battery pack combination can be stood on the base surface in one rotational orientation of the battery pack.
    • 电池供电的驱动器工具具有工具壳体,其具有插座型耦合器,其以四种不同的旋转取向中的任何一种接收电池组的插头型耦合器。 电池组上的四个键被接收在工具壳体上的四个键槽中,用于不可旋转的接合,这些部件由电池组上的分离卡环保持,凸轮经过工具壳体上的四个凸轮肩部,使得部件自动 响应于简单的推拉动作,卡扣接合和分离。 电池组包括串联连接在正端子和负极端子之间的多个电池单元,其被设计成在电池组的四个旋转取向中的任何一个中分别接合工具壳体上的正极端子和负极端子。 电池组具有平坦的基面,该部分被设计成使得工具/电池组组合能够以电池组的一个旋转取向站立在基座表面上。
