Crossed connector of building block robot

The invention discloses a crossed connector of a building block robot. The crossed connector comprises four long-strip-shaped insertion heads, the four long-strip-shaped insertion heads are connectedin a cross shape, connecting pieces are arranged at the joints of the four long-strip-shaped insertion heads, and insertion holes are formed in the connecting pieces. The crossed connector has the advantages that through the development of the crossed connector, splicing of different programs is completed to achieve the effect which can only be originally achieved with multiple connectors, the diversity and flexibility of product splicing are effectively improved, and a new experience effect is provided; the splicing effect which cannot be originally achieved is achieved by the crossed connector through effective butt joint of the insertion heads and insertion holes of the crossed connector with other building block set-up products and connectors, the enrichment effect of the programs is effectively improved, diff
