An inclination-adjusting structure is mounted on a lower portion of a table structure. A coupling bracket 2 is firmly mounted under a table plate (1). Several slide chutes 21 are formed longitudinally on the coupling bracket 2. Several positioning holes 22 are arranged in a row between two of the slide chutes 21. A disk-shaped plate 3 is mounted under the coupling bracket 2. The disk-shaped plate 3 has an arc-shaped surface 31. Two slide ribs 32 are formed on the arc-shaped surface 31 in locations corresponding to the slide chutes 21 of the coupling bracket 2. A positioning pillar 35 is mounted on the arc-shaped surface 31 in the same direction as the positioning holes 22. The slide ribs 32 are inserted into the slide chutes 21 if the coupling bracket 2 is coupled with the disk-shaped plate 3. The positioning pillar 35 can be inserted into different positioning hole 22. In addition, an angle of inclination of the table plate 1 is adjustable by shifting the coupling bracket 2. The table structure can also include an elevating device (5) for elevating the table plate. The elevating device moves an inner sleeve 413 having recessed slides (414) within an outer sleeve 411 having protruding slides 412. |
