Apparatus for Adjusting the Height of a Table

摘要

A table is provided with a height-adjusting apparatus. The height-adjusting apparatus includes a post, an elevating unit and an operating unit. The post includes an external tube and an internal tube. The internal tube includes a lower end telescopically inserted in the external tube and an upper end for supporting the table. The elevating unit includes a threaded rod and a nut. The threaded rod is connected to the internal tube so that the threaded rod is rotatable but not rectilinearly movable relative to the internal tube. The nut is non-movably connected to the external tube. The nut is engaged with the threaded rod. The operating unit is operable to rotating the threaded rod relative to the nut to rectilinearly move the threaded rod relative to the nut. Thus, the internal tube is rectilinearly movable relative to the external tube.
