Furthermore, the lifting arm assembly comprises two mutually pivoted support rods, the mutually pivoted support rods are arranged in a cross manner, the upper ends of one pair of mutually parallel support rods are pivoted with the table plate supporting seat, the lower ends of the pair of mutually parallel support rods are in sliding connection with the second guide rail, the upper ends of the other pair of mutually parallel support rods are in sliding connection with the first guide rail, and the lower ends of the pair of mutually parallel support rods are in pivoting connection with the second guide rail; the second support beam is connected between a pair of support bars that are parallel to each other.

Further, a first guide rail is arranged on the table plate supporting seat; and a second guide rail is arranged on the base.

Further, the table plate is connected with the table plate supporting seat through screws. The screw connection cost is low and the effect is good.

Further, two symmetrical installation blocks are fixedly connected to the bottom surface of the table plate, and keyboard trays parallel to the table plate are fixedly connected to the bottom surfaces of the installation blocks. The keyboard tray and the desk plate are in a certain height difference due to the arrangement of the mounting blocks, so that the keyboard is more comfortable when people operate the keyboard.

Furthermore, the bottom of the table board is fixedly connected with a power supply box. The power supply box is convenient for accommodating a power supply and a power line.

Further, the upper surface of the table plate is provided with an article placing groove. The article placing groove is convenient for people to prevent living goods such as mobile phones and flat plates, and brings convenience to people.

Further, the base is U type and integrated into one piece. The manufacture is convenient, and the cost is saved.

Furthermore, one side of the keyboard support close to the human body is in an inwards concave arc shape. The comfort level of using the keyboard tray is improved.
