摘要： A portable power tool or appliance, such as a cordless grass shear, may be slidably received within a unitary stirrup. A flexible flap on the stirrup carries a detent button that is automatically snapped into a screw-hole on the clam-shell power tool housing, as the power tool is fully seated within the stirrup. The flap may be flexed manually to release the detent button, thereby facilitating quick disengagement between the power tool and the stirrup. The stirrup carries ground-engaging wheels to facilitate manual movement and guidance of the power tool during its stand-up operation. An extension handle in the form of a tubular wand is secured to the stirrup and extends upwardly therefrom. A top handle with a switch is provided on the end of the wand. An electrical cable is connected to the switch, extends downwardly therefrom within the wand, and exits from the stirrup above the power tool. The end of the cable carries a plug adapted to be received within a receptacle on the power tool. The receptacle has spaced contacts formed as a continuation of the contacts of the tool switch. This provides a parallel connection, bypassing the tool switch and, at relatively low cost, facilitating manual control by the switch on the top handle.
摘要翻译：便携式电动工具或器具，例如无绳草剪，可以可滑动地接收在单一马镫内。马镫上的柔性翼片带有一个定位按钮，自动锁定在蛤壳式电动工具外壳上的螺孔中，因为电动工具完全固定在马镫内。可以手动弯曲翼片以释放制动按钮，从而有助于电动工具和马镫之间的快速分离。马镫带有接地轮，以便在其立式操作期间手动移动和引导电动工具。管状棒形式的延伸手柄固定在马镫上并从其向上延伸。在魔杖的末端提供带有开关的顶部手柄。一根电缆连接到开关上，从该杆向下延伸，并从电动工具上方的马镫上出来。电缆的端部承载适于容纳在电动工具上的插座内的插头。插座具有形成为工具开关的触点的延续部的隔开的触点。这提供了并联连接，绕过工具开关，并且以相对较低的成本，便于手柄上的手柄控制。
