Planar three-dimensional dual-purpose color card

The utility model discloses a planar and three-dimensional dual-purpose color card which comprises a first color card, bending connecting pieces are fixedly arranged on the two sides of the first color card, second color cards are fixedly arranged on the top between the two bending connecting pieces, and adjusting structures are fixedly arranged on the two sides between the two second color cards. The color card can be used in a planar mode and a three-dimensional mode, random switching between the planar mode and the three-dimensional mode can be achieved, use is more convenient, the sleeve is rotated clockwise to drive the first threaded rod and the second threaded rod to move towards the two sides, the middles of the two bent connecting pieces are pushed to move towards the two sides, then the two bent connecting pieces are pushed to be straight, and the three-dimensional color card is formed. The sleeve is rotated anticlockwise, the first threaded rod and the second threaded rod are contracted into the sl
