An electrical apparatus comprises an extension portion extending in a direction that intersects the direction in which a battery attachment surface of a battery base extends. A battery includes a plurality of battery cells with negative electrode side end faces. The battery has negative electrode side holding portions adjacent to the exterior of each of the negative electrode side end faces. The negative electrode side holding portions are located closer to the inner region of the center of gravity of the apparatus than a virtual plane to which a lateral rear side of the extension portion and a lateral rear side of the battery are tangent.

An adapter connects a plurality of first battery packs, each having a nominal voltage of about 18-36 volts, in series to an power tool having a rated voltage that is 36 volts or higher. The power tool includes a second battery interface configured to removably attach a second battery pack. The adapter includes a plurality of first battery interfaces configured to removably attach the plurality of first battery packs and having a different physical configuration than the second battery interface. A connector of the adapter is configured to be removably attached to the second battery interface. A plurality of visual indicators is disposed on the adapter such that they have the same or substantially the same illumination direction and they visually indicate at least a level of charge of each of the first battery packs attached to the adapter.

A motorized window covering is presented having an elongated hollow rod. A battery tube is positioned within the hollow rod. The battery tube has a hollow interior with an elongated spring therein and a stop positioned adjacent an open end of the battery tube. An end cap closes the open end of the battery tube. A plurality of batteries are inserted in end-to-end alignment into the hollow interior of the battery tube. As each battery is inserted, the stop deflects thereby allowing the battery past the stop. Once each battery passes the stop, the stop moves into a stop position thereby holding the battery within the battery tube. To remove each of the plurality of batteries, the stop is deflected and the spring forces the battery out of the hollow interior of the battery tube. The battery tube is electrically connected to a motor that when activated rotates the rod thereby operating the window covering.

摘要:
The invention relates to a cutting tool setting system comprising a tool head for the settable holding of a cutting tool, said head comprising an adjustment device for the cutting tool. The cutting tool setting system comprises a setting tool which can be mechanically removably engaged in the tool head at an interface for adjusting the adjustment device in the tool head. The setting tool comprises a shaft body having a key part. A key engagement for actuating the adjustment device is designed on the tool head. The key part can be displaced relative to the shaft body in the direction of the longitudinal axis of said body in order to selectively couple and release the key part of the setting tool and the key part at the interface of the tool head.
