[0025] The following is a detailed description of the working principle of the portable display teaching aid for teaching drama, film and television literature.

[0026] like Figure 1-7As shown, when in use, the card box cover 11 is punched, the adjustment rod 27 is pressed to drive the moving plate 25 to move on the guide rod 24, and the moving plate 25 moves to compress the arc spring piece 26 to generate elastic force. At this time, the moving lifting plate 23 moves up in the lifting seat 21 to adjust the display height of the display board 37. After the adjustment is completed, the adjustment rod 27 is released, and the arc spring piece 26 restores the elastic force to drive the adjustment rod 27 to be clamped into the adjustment hole 22 of the current height and fixed. Then, the display board 37 is rotated by the straight rod 35 until the rod hole 36 is located at the positive position of the straight rod 35.

The plate 383 moves downward to compress the compression spring 382 to generate elastic force. When the turntable 32 rotates to the next circular hole groove 39 and contacts the ball 384, the compression spring 382 restores the elastic force to drive the ball 384 to rebound into the circular hole groove 39. When the turntable 32 continues to rotate, the ball 384 separates from the circular hole groove 39 again and enters the next circular hole groove 39 to rebound. In this way, the angle of the display board 37 can be adjusted. When it is needed to be stored after use, the display board 37 is turned flat, and the bolt 34 is rotated in the opposite direction to separate it from the rod hole 36. The straight rod 35 rotates the display board 37 until the rod hole 36 is located directly below the straight rod 35, and the adjusting rod 27 is pressed to separate from the adjusting hole 22. The adjusting rod 27 is inserted into the adjusting hole 22 at the bottom by the above method. At this time, the display board 37 can be stored in the base 1, and the box cover 11 is flipped over and covered on the top of the base 1. At this time, the first magnet 13 and the second magnet 14 attract each other, thereby fixing the box cover 11. The display board 37 can be moved by holding the handle 12, which is convenient for carrying the display board 37.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
