[0022] Please refer to Figures 1 to 5 As shown, a dance teaching demonstration device in this embodiment includes a display screen 1 and a mobile bracket 17. The mobile bracket 17 enables the entire display screen 1 to be conveniently moved to different teaching venues, providing the convenience of movement for the display screen 1 and improving the flexibility of use of the device. Specifically, a first mounting card frame 2 and a second mounting card frame 4 are installed on the mobile bracket 17, and a storage board 11 is fixedly connected to the bottom of each of the first mounting card frame 2 and the second mounting card frame 4. A reinforcing cross bar 3 is fixedly connected to the left end of the first mounting card frame 2, and the reinforcing cross bar 3 is located at the bottom of the display screen 1. The left end of the reinforcing cross bar 3 is fixedly connected to the second mounting card frame 4, and both the first mounting card frame 2 and the second mounting card frame 4 are inserted into the bottom of the display screen 1.

[0023] A limiting bracket 5 is fixedly connected to one side of the first mounting card frame 2 and one side of the second mounting card frame 4. A limiting frame 6 is fixedly connected to each limiting bracket 5. The two limiting frames 6 are symmetrically distributed left and right with the display screen 1 as the center, and the limiting frame 6 is in contact with the bottom surface of the display screen 1, playing a role of supporting and limiting the display screen 1 from the bottom.
