The specific embodiment
The below makes a detailed explanation the specific embodiment of the present utility model with reference to the accompanying drawings.
Embodiment
Extremely shown in Figure 8 according to Fig. 1, the described a kind of multifunctional lifting desk of present embodiment, the panel 5 that includes two table legs 1 and be positioned at table leg 1 top, slide respectively on described two table legs 1 and be provided with adjusting rod 3, adjusting rod 3 is set in the table leg 1, is connected by fixed tight knob 2 between adjusting rod 3 and the table leg 1; Described adjusting rod 3 upper ends are fixedly installed supporting surface 8, and supporting surface 8 is made of the metal pipe material welding, and supporting surface rear end, 8 top and panel 5 are hinged, also are connected with a panel angle adjusting piece 7 between panel 5 and the supporting surface 8.Described supporting surface 8 and panel 5 hinged positions are positioned at the rear of desk, when namely desk uses near user's a side.
