摘要：A height adjusting apparatus includes a vertical outer tube that is adapted to befixed on the base, and a vertical inner tube that is adapted to be fixed on the workingtable and that is mounted telescopically on the outer tube. A guiding device guides theinner tube to move vertically within the outer tube while preventing rotation of the innertube relative to the outer tube. An externally threaded vertical rod is journalled in theouter tube, and engages threadably an internal thread portion of the inner tube. Adriving mechanism includes a driven bevel gear that is mounted coaxially and fixedly onthe vertical rod, and a driving bevel gear, which is mounted rotatably in the outer tubeand which meshes with the driven bevel gear. The driving bevel gear rotates about ahorizontal axis so as to rotate the vertical rod, thereby moving the inner tube verticallywithin the outer tube. An adjusting member is mounted rotatably on an outer surface ofthe outer tube, and is connected fixedly to the driving bevel gear for driving the drivingbevel gear. Preferably, an annular water seal is interposed between the inner tube andthe upper end portion of the outer tube to establish a water-tight seal therebetween.
