Abstract
An elevation table includes a tabletop and a table leg frame mounted to the tabletop. The table leg frame includes a fixed leg, a movable leg insertable into the fixed leg, and an extendible/retractable bar arranged inside the fixed leg and the movable leg. The movable leg has an end connected to the tabletop and an opposite end receiving a first positioning sleeve to fit thereto and insertable into the fixed leg. The fixed leg has an end into which the movable leg is insertable and receives a second positioning sleeve to fit thereto. The first and second positioning sleeves each include embedding holes formed in at least two sidewalls thereof and the embedding holes receive embedded pieces to be fit therein. The first and second positioning sleeves are in point contact with surfaces of the movable leg and the fixed leg by means of the embedded pieces.
