[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4As shown, the utility model provides a display device, including a display board 1, both sides of the back side of the display board 1 are threadedly connected with connecting plates 2, an electric telescopic rod 3 is fixedly connected to the axis of the back side of the connecting plate 2, a cavity is opened on one side of the display board 1, the internal sliding rod of the cavity is connected with an extension plate 4, a positioning rod 5 is threadedly penetrated on one side of the bottom of the display board 1, and one end of the positioning rod 5 conflicts with one side of the bottom of the extension plate 4.

[0021] By setting the extension plate 4, the display board 1 and the positioning rod 5, when the information publicity personnel need to publicize more information, the publicity personnel can hold the protrusion 8 to slide the extension plate 4 out of the cavity, so that the extension plate 4 is fully opened, and then the publicity personnel can twist the positioning rod 5 so that the positioning rod 5 passes through the bottom of the display board 1, so that one end of the positioning rod 5 presses one side of the bottom of the extension plate 4, so that the extension plate 4 is fixed, thereby playing the role of increasing the publicity information area;

[0022] Through the arrangement of the electric telescopic rod 3 and the display board 1, during use by the staff, the staff can turn on the power of the electric telescopic rod 3 according to the actual height of the display board 1, so that the electric telescopic rod 3 drives the connecting plate 2 and the display board 1 to move upward or downward, thereby facilitating the staff to adjust the height position of the display board 1.
