the fluency of the use process of the demonstration equipment is enhanced; because the present invention is provided with the stabilizing rod 15; after the use of the demonstration device is finished, the stabilizing rod 15 is formed by rotationally connecting two parts; rotating the stabilizing rod 15 close to one end of the second stabilizing groove 14 by ninety degrees anticlockwise, and then drawing out the whole stabilizing rod 15 to enable the stabilizing block 16 to be separated from the second stabilizing groove 14; then the display board 7 is rotated downwards, so that the display board 7 is rotated from the vertical state to the horizontal state to retract the display board 7; when the display board is required to be used, the display board 7 is rotated upwards to restore the vertical state, then the stabilizing block 16 is inserted into the second stabilizing groove 14, when the stabilizing block 16 enters the second section of the stabilizing groove, the stabilizing block 16 is rotated ninety degrees clockwise, so that the position of the stabilizing block 16 corresponds to that of the third section of the second stabilizing groove 14, and then the stabilizing block 16 extends into the third section of the second stabilizing groove 14; fixing the display board 7 in a vertical state; the display board 7 is more convenient to store, so that the occupied volume of the demonstration equipment is reduced during transportation; in addition, the limiting block 17 is arranged, so that the stabilizing rod 15 cannot be completely separated from the first stabilizing groove 13 in the process of pulling the stabilizing rod 15 to separate the display board 7 from the back sliding block 93; the middle part of the stabilizing rod 15 is designed to be in a semi-circular arc shape, so that fingers can be more conveniently stretched into the stabilizing rod 15; the convenience of the use of the demonstration equipment is further improved.
The front, the back, the left, the right, the upper and the lower are based on the observation angle of the person, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
