When the electric push rod 5 is started, its output end is extended and retracted, which can drive the support frame 4 to move up and down, and then drive the first display board 1 to move up and down, so as to adjust the height of the display board for education and training according to the needs of users.

[0026] Universal wheels 7 are installed at the four corners of the bottom surface of the base plate 6, and every two universal wheels 7 form a group. The two groups of universal wheels 7 are symmetrically arranged with the mid-vertical line of the base plate 6 as the symmetry axis. The universal wheels 7 have a self-locking function, which can fix the display board for education and training in the position of use. The universal wheels 7 can be used to facilitate the movement of the display board for education and training.

[0027] Four reinforcing blocks 8 in a circular array are fixedly connected to the upper surface of the base plate 6, and the four reinforcing blocks 8 are all fixedly connected to the electric push rod 5. The inner wall and the bottom surface of the reinforcing block 8 are respectively fixedly connected to the outer surface of the electric push rod 5 and the upper surface of the base plate 6, which can provide auxiliary support for the electric push rod 5, improve the structural strength of the electric push rod 5, and thereby improve the stability of the display board for education and training when in use.

[0028] Two hooks 11 are arranged on the upper surface of the first display board 1, and the two hooks 11 are arranged symmetrically. The two symmetrically arranged hooks 11 can conveniently hang the display board for education and training, so that it is fixed at the position of use and has a stable center of gravity.

[0029] An adjustment mechanism 2 is arranged outside the first display board 1 , and the adjustment mechanism 2 includes two servo motors 201 and two second display boards 205 .
