As shown in fig. 1 and 2, the liquid crystal display 1 is adopted as the background of the displayed commodity, and the video related to the commodity can be played in the actual display, so that the commodity placed on the display board under the support of the video can be better displayed. This novel braced frame body 2's lower extreme has four wheels 21, and this is novel like this can conveniently transport the place that needs and carry out the commodity show. Before the exhibition, the articles to be exhibited are placed on the exhibiting board 4 for exhibiting. After the 220V power supply enters the two power supply input ends of the switching power supply U1, pins 3 and 4 of the switching power supply U1 output stable 12V dc power supply to enter the power supply input end of the control circuit, so that the control circuit is in an electrified working state. When the commodity needs to be displayed and rotated for displaying, a user presses a third transmitting button S3 of the wireless transmitting circuit U3, then, the wireless transmitting circuit U3 transmits a third wireless closing signal, after the wireless receiving circuit module U2 receives the third wireless closing signal, a pin 6 of the wireless receiving circuit module U2 outputs a high level, the high level is subjected to voltage reduction and current limitation through the resistor R3 and enters the base electrode of the NPN triode Q3, then the NPN triode Q3 is conducted with the collector to output a low level, the low level enters the negative power input end of the relay K3, and the relay K3 is electrified to attract the control power input end and the normally open contact end of the relay K3 to be closed. Because two normally open contact ends of the relay K3 are respectively connected with two power input ends of the motor reducing mechanism M1, the motor reducing mechanism M1 can work as a power output shaft thereof to drive the display board 4 and the display articles (commodities) on the display board 4 to rotate, so that the commodities can be displayed in a dynamic mode. When the commodity is not required to be rotated for display, the user presses the transmitting button S3 again, so that the wireless transmitting circuit module U3 transmits a third path of wireless open-circuit signal, the wireless receiving circuit module U2 receives the rear 6 pins and stops outputting high level, the relay K3 is powered off and is not attracted any more, the motor reducing mechanism M1 also stops working, and the display board can be stopped at a certain angle to rotate the static display commodity.

As shown in fig. 1 and 2, when the displayed commodity is a small commodity, and the height of the display board 4 needs to be increased in order to achieve a good display effect, a user presses the first transmitting button S1 of the wireless transmitting circuit U3, so that the wireless transmitting circuit U3 transmits a first path of wireless closing signal, after the wireless receiving circuit module U2 receives the first path of closing signal, a pin 4 of the wireless receiving circuit module U2 outputs a high level, the high level is reduced in voltage and limited in current through the resistor R1 and enters the base of the NPN triode Q1, the NPN triode Q1 turns on a collector to output a low level, the low level enters the negative power input end of the relay K1, and the relay K1 is powered to attract the control power input end and the normally open contact end of the relay K1 to be closed.

After the commodity rises to a certain height, the user presses the transmission button S1 again, and then wireless transmitting circuit module U3 launches the wireless signal of opening a way all the way, and wireless receiving circuit module U2 receives the back 4 feet and can stop outputting high level, and then relay K1 loses the electricity and no longer actuation, and electric telescopic handle M just also can stop working, just so can show relatively little commodity on a certain height. When the displayed commodity is a large commodity and the height of the display board 4 needs to be reduced in order to achieve a good display effect, a user presses the second transmitting button S2 of the wireless transmitting circuit U3, then, the wireless transmitting circuit U3 transmits two paths of wireless closing signals, after the wireless receiving circuit module U2 receives the second path of closing signals, a pin 5 of the wireless receiving circuit module U2 outputs a high level, the high level is subjected to voltage reduction and current limiting through a resistor R2 and enters a base electrode of an NPN triode Q2, then the NPN triode Q2 is conducted with a collector to output a low level, the low level enters a negative power supply input end of a relay K2, and the relay K2 is electrified to attract the control power supply input end and a normally open contact end of the relay K2 to be closed. Because two normally open contact ends of the relay K2 are respectively connected with the negative and positive power supply input ends of the electric telescopic rod M, the electric telescopic rod M can work by an electric machine at the moment, and the piston rod of the electric telescopic rod M can drive the motor reducing mechanism M1 and the commodity on the display board 4 to descend. After the commodity falls to a certain height, the user presses the transmitting button S2 again, so the wireless transmitting circuit module U3 transmits a second path of wireless open-circuit signal, the wireless receiving circuit module U2 receives the back 5 feet and stops outputting high level, further the relay K2 is de-energized and is not attracted any more, the electric telescopic rod M also stops working, and thus a relatively small commodity can be displayed at a certain height. Through above-mentioned circuit effect, this is novel both can be suitable for smallclothes commodity show, still is applicable to the show of major possession commodity, can bring certain promotion more or less to the development of electricity merchant trade. The resistances of the resistors R1, R2 and R3 are 1K; the model numbers of NPN triodes Q1, Q2 and Q3 are 9013; the relays K1, K2, K3 are DC12V relays.
