    • A wand for an appliance includes first and second tubes and a support mechanism, in which the second tube slides telescopically within the first tube along a common axis. The first and second tubes are arranged to be selectively secured to one another in an extended position or to allow movement therebetween and the support mechanism is located between overlapping portions of the tubes. The support mechanism includes tapered portions arranged to provide support between the tubes at separate points along the common axis of the tubes. By supporting adjacent tubes at a plurality of points along the common axis, the tubes are held more firmly with respect to one another. One tapered portion is able to move with respect to the tubes along the common axis, which reduces play between the tubes.
    • 用于器具的魔杖包括第一和第二管和支撑机构,其中第二管沿着共同的轴线可伸缩地在第一管内滑动。 第一和第二管被布置成在延伸位置中彼此选择性地固定或允许它们之间的移动,并且支撑机构位于管的重叠部分之间。 支撑机构包括锥形部分,其被设置成沿着管的共同轴线的分开的点处在管之间提供支撑。 通过沿着公共轴线在多个点处支撑相邻的管,管被相对于彼此更牢固地保持。 一个锥形部分能够沿着公共轴线相对于管移动,这减少了管之间的游隙。
