The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Referring to fig. 1-3, a teaching demonstration device comprises a base 1, two fixing rods 2 are arranged on the top end of the base 1, a connecting rod 3 is arranged between the two fixing rods 2, a first plate 4 is arranged on the outer wall of the connecting rod 3, a second plate 5 is arranged on one side, located on the first plate 4, of the outer wall of the connecting rod 3, a third plate 6 is arranged on one side, located on the second plate 5, of the outer wall of the connecting rod 3, a fourth plate 7 is arranged on one side, located on the third plate 6, of the outer wall of the connecting rod 3, limiting plates 8 are arranged between the first plate 4, the second plate 5 and the third plate 6, and rotating plates 9 are arranged on the backs of the first plate 4, the second plate 5, the third plate 6 and the fourth plate 7.

Please refer to fig. 1, the first plate 4, the second plate 5, the third plate 6, the fourth plate 7 and the connecting rod 3 are rotatably connected by a rotating shaft, so that the first plate 4, the second plate 5, the third plate 6 and the fourth plate 7 can rotate conveniently.

Please refer to fig. 3, the four rotating plates 9 are respectively fixed to the first plate 4, the second plate 5, the third plate 6, and the fourth plate 7 by the rotating shaft, so that the rotating plates can move downward by gravity when the first plate 4, the second plate 5, the third plate 6, and the fourth plate 7 are turned over.

Please refer to fig. 2 and 3, the numbers "0" are printed on the front ends of the first, second, third and

fourth boards

4, 5, 6 and 7, and the numbers "1" are printed on the back ends of the first, second, third and

fourth boards

4, 5, 6 and 7, so as to facilitate the learners to better understand the binary system.

Please refer to fig. 2, the limiting plate 8 is fixedly connected to the connecting rod 3 through a bolt, so that the limiting plate 8 limits the rotating plate 9 to prevent the rotating plate 9 from rotating continuously.

Please refer to fig. 3, the back of the first plate 4, the second plate 5, the third plate 6, and the fourth plate 7 and one side of the rotating plate 9 are all provided with a limiting rod to limit the moving of the rotating plate 9.

The working principle is as follows: when the device is used, a teacher shifts a first plate 4, the first plate 4 rotates and turns over through a rotating shaft, the number on the first plate 4 is changed from '0' to '1', and the first plate 4 rotates, so that a rotating plate 9 originally at the bottom end of the first plate 4 is turned over to the top end of the first plate 4, and the rotating plate 9 falls at the top end of a limiting plate 8 under the influence of gravity, when the teacher shifts the first plate 4 for two times, the first plate 4 rotates and turns over through the rotating shaft, the number on the first plate 4 is changed from '1' to '0', and the first plate 4 rotates to drive the rotating plate 9 to rotate, the rotating plate 9 drives the second plate 5 to turn over, the number on the second plate 5 is changed from '0' to '1', the rotating plate 9 at the bottom end of the second plate 5 is turned over to the top end of the second plate 5, the rotating plate 9 falls at the top end of the limiting plate 8 under the influence of gravity, and the first plate 4 falls vertically under the influence of gravity, and the limiting rod limits the limiting rod to avoid rotary motion, and the first plate 4 is stirred for multiple times to turn over, so that the second plate 5, the third plate 6 and the fourth plate 7 are driven to turn over, binary explanation is carried out, and students can learn more vividly.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
