[0029] In this embodiment, Figure 1As shown, the lower end of the display board 2 is hinged to the left end of the base 1, and the two can rotate relative to each other. The front side (right side) of the display board 2 is used to paste the posters to be displayed, and the back side (left side) of the display board 2 is hinged with a support rod 3, and the lower end of the support rod 3 is hinged with an adjusting block 4. At the same time, a slide groove 5 adapted to the adjusting block 4 is opened on the top surface of the base 1, and the slide groove 5 is distributed along the length direction of the base 1. The adjusting block 4 is assembled in the slide groove 5. The adjusting block 4 can slide relative to the base 1. The bottom surface of the slide groove 5 and the bottom surface of the adjusting block 4 are in oblique straight surface contact to form a wedge structure. In this way, the angle between the display board 2 and the base 1 can be changed through the support rod 3 by sliding the adjusting block 4 along the length direction of the slide groove 5, thereby changing the display angle of the display board 2, which is convenient for the publicity and display of posters, and also convenient for students, parents, teachers and other personnel to watch the content displayed on the posters.

[0030] Preferably, the top surface of the base 1 is an inclined surface inclined toward the display board 2, the bottom surface of the chute 5 is parallel to the top surface of the base 1, and the bottom surface of the adjustment block 4 is adapted to the inclined surface. Specifically, the top surface of the base 1 is an inclined straight surface facing right, that is, the vertical section of the base 1 is a right-angled triangle, the bottom surface of the adjustment block 4 is adapted to the top surface of the base 1, and the vertical section of the adjustment block 4 is also a right-angled triangle. The base 1 and the adjustment block 4 are both wedge-shaped, and the bottom surface of the chute 5 is parallel to the top surface of the base 1. In this way, the bottom surface of the chute 5 is also an inclined surface facing the display board 2. Figure 2 As shown, when the adjusting block 4 slides toward the display board 2, the height of the support rod 3 decreases, and the display board 2 rotates toward the top surface of the base 1 (counterclockwise) under the action of its own gravity, and the angle between the display board 2 and the base 1 decreases. Conversely, when the adjusting block 4 slides in the direction away from the display board 2, the height of the support rod 3 increases, and the support rod 3 pushes the display board 2 to rotate in the direction away from the base 1 (clockwise), so that the angle between the display board 2 and the base 1 increases. Therefore, by changing the sliding position of the adjusting block 4 on the top surface of the base 1, the inclination angle of the display board 2 can be adjusted, and then the display angle of the poster can be adjusted to facilitate display.
