ABSTRACT:
The present invention provides a leg support structure of a computer desk capable of synchronous sliding movement, comprising a stand, a leg pad, two L-shaped prop stands and two sliding collars. The stand is formed into an inverse U-shape, and the leg pad is formed into a planar configuration. The leg pad comprises a lower pivot opening and an upper pivot opening formed on both sides of the leg pad, wherein the locations of the lower openings and the upper pivot openings are corresponding to positions of a lower pivot and two L-shaped prop stands. The lower pivot is positioned though the lower pivots openings of the leg pad in order to pivot to a support located at a center of the two arcing grooves. The L-shaped prop stands, the two sliding collars, the pulley and a slider are engaged in such that various elevation changes can be achieved.
