    • A miter circular saw includes a base on which a workpiece is placed, a tiltable saw blade assembly mounted on the base, and a work support fence that includes a fixed element with a first support surface and a movable element with a second support surface, both of which are mounted on the base for supporting the workpiece during cutting. The movable element is hinged to the top end of the fixed element to allow the movable element to pivot between a raised position, above the fixed element, and a lowered position. In the raised position, the movable element engages the fixed element so as to fix the movable element and prevent it from inadvertently falling rearward into the lowered position. In the raised position, the movable element places the second support surface flush with the first support surface of the fixed element. When the movable element is in the lowered position, the work support fence is sufficiently low to avoid interference with the locus of the saw blade assembly in its maximally tilted position.
    • 一个斜切的圆锯包括一个放置工件的基座,一个安装在基座上的可倾斜的锯片组件和一个工件支承围栏,它包括具有第一支撑表面的固定元件和带有第二支撑表面的可移动元件 其安装在基座上,用于在切割期间支撑工件。 可移动元件铰接到固定元件的顶端,以允许可移动元件在固定元件上方的升高位置和下降位置之间枢转。 在升高位置,可移动元件与固定元件接合,以固定可动元件,并防止其不经意地向后落入下降位置。 在升高位置,可移动元件将第二支撑表面与固定元件的第一支撑表面齐平。 当可移动元件处于降低位置时,工作支撑栅栏足够低以避免与锯片组件的位置处于最大倾斜位置的干涉。

    • A charger (1) includes a box enclosure (2), terminals (11, 12, 13), and a protective terminal cover (14) which in turn includes a top plate (15) extending at right angles to a pair of guide rails (6). The terminal cover (14) is pivotally supported by a pair of pivot pins (17) inside the box enclosure (2) such that the terminal cover (14) is pivotal between a protruding position, in which the top plate (15) is located directly above and protects the terminals and a retracted position, in which the terminal cover (14) is completely retracted inside the box enclosure (2). The terminal cover (14) is biased to the protruding position by a torsion spring (18) when a battery pack (40) is not set on the charger (1) for a recharge, whereas the terminal cover is manually moved to the retracted position against the biasing force of the torsion spring when the battery pack is slid on the charger into a set position.
    • 充电器(1)包括盒壳体(2),端子(11,12,13)和保护端子盖(14),保护端子盖(14)又包括与一对导轨成直角延伸的顶板 (6)。 端子盖(14)由箱体(2)内的一对枢销(17)可枢转地支撑,使得端盖(14)在顶板(15)所在的突出位置之间枢转 直接在上方并保护端子和缩回位置,其中端子盖(14)完全缩回到箱体(2)内。 当电池组(40)没有设置在充电器(1)上用于充电时,端子盖(14)被扭簧(18)偏置到突出位置,而端子盖手动地移动到缩回位置 当电池组在充电器上滑动到设定位置时,抵抗扭簧的偏置力。
