The fixed plate is provided with a vertical slideway 2 for the rotating shaft 4, and the rotating shaft 4 can do vertical linear motion relative to the fixed plate through the vertical slideway 2.

When the rotating shaft 4 is located at the lowest point of the vertical slideway 2, the rotating plate is overlapped with the fixed plate, and the highest point and the lowest point of the vertical slideway 2 are symmetrical by taking the horizontal central line of the fixed plate as a symmetrical line so as to ensure that a user can use the vertical slideway 2 to move the rotating plate upwards to enable the rotating plate and the fixed plate to be located at the same horizontal line after the rotating plate rotates 180 degrees, so that the longitudinal space can be saved, and the explanation of the user can be facilitated.

The front end face of the front rotating plate 10 and the rear end face of the rear rotating plate 9 are respectively provided with a stabilizing block 12, the stabilizing blocks 12 are embedded into the fixing plate, the fixing plate is provided with arc-shaped slideways 13 corresponding to the stabilizing blocks 12 so that the stabilizing blocks 12 can rotate along with the rotating plates, and small gaps are formed between the arc-shaped slideways 13 and the stabilizing blocks 12 so that the rotating plates can rotate more stably by using friction force between the stabilizing blocks 12 and the arc-shaped slideways 13.

When the stabilizing block 12 is located at the lowest point of the arc-shaped slideway 13, the fixed plate is superposed with the rotating plate, and the rotating plate is supported by utilizing the mutual matching between the arc-shaped slideway 13 and the stabilizing block 12, so that the rotating plate cannot move randomly in the daily storage process.

When the stabilizing block 12 is located at the highest point of the arc-shaped slideway 13, the relative height of the maximum transverse diameter point of the stabilizing block 12 is higher than that of the fixed plate so that the fixed block moves upwards along with the rotating plate, namely the stabilizing block 12 can be separated from the fixed plate in the process of moving upwards along with the rotating shaft 4, namely the rotating plate does not limit the rotation by 180 degrees.

When the stabilizing block 12 is located the arc slide 13 peak, the relative height of the terminal surface is less than the fixed plate under the stabilizing block 12 in order to increase the restriction to stabilizing block 12 for the rotor plate is influenced by arc slide 13 and can not continue to rotate when the rotor plate rotates 90, can maintain 90 states, fixed plate and rotor plate are the cuboid in order to distinguish the rotor plate, rotate 90 and rotate 180 through distinguishing the rotor plate and deal with different change curve demands, rotate 90 simultaneously and also can make the change curve on the rotor plate and the change curve on the fixed plate form the contrast.

And display mechanisms are arranged on the fixed plate and the rotating plate to display the economic change curve.

The exhibition mechanism is including setting up at the inside dead lever 8 of fixed plate and exhibition board, dead lever 8 quantity is a plurality of, and parallel arrangement.

A plurality of show balls 7 of having arranged side by side on single dead lever 8, dead lever 8 runs through show ball 7, rotates with show ball 7 and is connected, both ends face all is provided with show groove 6 to show ball 7 around 3 preceding terminal surfaces of preceding fixed plate, 11 rear end surfaces of after-fixing board, the rotor plate so that the user can observe some show balls 7 directly perceivedly.

The surface of the display ball 7 is sprayed with dye, the colors of the dye sprayed on the front end face and the rear end face of the display ball 7 are different, and in the actual use process, a user can display a change curve path by using different colors by rotating the display ball 7 according to an economic change curve.

The left side and the right side of the lower end of the fixing plate are respectively provided with a supporting leg 5 for supporting the device.

Fixed plate and show board up end all are provided with handle 1, can make this device more convenient for remove through handle 1, simultaneously when the rotor plate rotates 90, handle 1 is located the rotor plate and keeps away from fixed plate one side relatively, the rotor plate lower extreme is kept away from fixed plate one side relatively and is lacked the support this moment, utilize handle 1's weight to help the rotor plate to keep 90 rotation, simultaneously when the rotor plate rotates 180, handle 1 is located the rotor plate lower extreme, again because handle 1 and supporting legs 5 relative highly uniform, handle 1 can play the supporting role to the rotor plate this moment, help the device stable.

The working principle is as follows: in the actual use process, the number of the graphs and the size of the graphs are determined according to the economic change curve to be displayed, the number of the rotating plates to be required, the state relation between the rotating plates to be required and the fixed plates to be required and the number of the fixed plates to be required are determined, then the rotating plates are rotated, the rotating plates are moved up and down according to requirements to meet the requirements, and finally the display ball 7 is shifted to display different colors.
