Abstract

An adjustable lift support apparatus includes a holder, a base, a first fixed shaft, a support, a second fixed shaft, and a transmission shaft. The first fixed shaft is connected to the base and the holder, and a first gear is mounted thereon. The second fixed shaft is connected to the support and the holder, and a fourth gear is mounted thereon. The transmission shaft is rotatably mounted on the holder, and a second gear is mounted thereon meshing with the first gear and a third gear is mounted thereon meshing with the fourth gear. The support is lifted or lowered by a force to make the second gear rotate with respect to the first gear which is fixed and the third gear rotate with respect to the fourth gear, so as to adjust the height of the support and maintain an included angle between the support and the base.
