    • It is an object of the invention to provide an effective technique for reducing the load of user's fingers in a power tool. A representative power tool includes a body, a tool bit, a driving means and a handgrip that extends from a grip proximal end on the side of the body to a grip distal end in a direction that crosses the axial direction of the tool bit. The power tool includes a holding optimization region that is arranged on the handgrip and shaped to match with the holding form of the fingers of the user when the user holds the handgrip. Specifically, the holding optimization region at least includes the rear end surface of the grip distal end region such that a normal on the rear end surface crosses an axis of the tool bit forward of the handgrip. As a result, according to the invention, the force of the user's fingers and palm on the handgrip can be optimized.
    • 本发明的目的是提供一种用于减少用户手指在电动工具中的负荷的有效技术。 代表性的电动工具包括主体,工具钻头,驱动装置和手柄,其从身体侧面的手柄近端延伸到与刀具的轴向方向交叉的方向上的手柄远端。 电动工具包括一个保持优化区域,该保持优化区域布置在手柄上并且在使用者握住手柄时成形为与使用者的手指的保持形式相匹配。 具体而言,保持优化区域至少包括握持部远端区域的后端面,使得后端面上的法线与手柄的前方的工具的轴线交叉。 结果,根据本发明,可以优化用户的手指和手掌在手柄上的力。
