Most of the existing lifting tables can only be used for users to sit and stand. It is bad for health to maintain unreasonable posture and long-term stiffness while sitting and working for a long time, and the psoas and spine may be severely damaged. Therefore, a table-on-table that can allow the user to sit and stand alternately to work appears. However, the existing table-on-table on the market has many defects. For example, in most cases, foot rods are arranged as telescopic sleeve structures; and the length of the foot rods is adjusted through matching of nuts and screws. It is inconvenient to operate when the table is adjusted, and it is difficult to quickly level a tabletop. In addition, for the common table-on-table that can realize vertical lifting, generally, both ends of the table are respectively provided with X-shaped lifting brackets, and lifting push rods are arranged between crossed rods. When a heavy object is put on one side of the table of this design for a long time, the stresses on both ends of the table is uneven and the table is difficult to keep horizontal and the lifting speeds of the lifting push rods on both sides shall be consistent, so that the whole table is complex in structure and high in cost.
