Abstract: A table stand includes a first pivoting stabilizer, a second pivoting stabilizer, a first height adjustable pole connected to the first pivoting stabilizer, a second height adjustable pole connected to the second pivoting stabilizer, a folding transmission mechanism separately connected to the first height adjustable pole and the second height adjustable pole, and a support crossbar connected to the folding transmission mechanism. The first pivoting stabilizer and the second pivoting stabilizer are movably connected to two ends of the support crossbar. Each of the first pivoting stabilizer and the second pivoting stabilizer includes a first blocking edge, a second blocking edge, and a first shaft sequentially passing through the first blocking edge and the second blocking edge. The support crossbar is disposed between the first blocking edge and the second blocking edge.

Abstract: A desk lifting structure contains: a horizontal rod, an actuation rod, and two legs. The horizontal rod includes two orifices and two locking grooves. The two locking grooves have two engagement portions, two openings, and two guide portions respectively. The actuation rod is located beside and is parallel to the horizontal rod, and the actuation rod includes two movable joints. The two legs include two movable supports and two holders individually. The movable supports have two connection members respectively, the two legs are connected with two ends of the actuation rod respectively, the two connection members have two side plates individually, and the two side plates have two first fixing apertures and two second fixing apertures respectively.
