The technical solution adopted for the present invention to solve the technical problems is: just round fancy ball is by assembly 1, assembly 2 ... totally 30 same components grafting of assembly 30 forms; Each assembly by the square of paper 1 of homalographic, square of paper 2 totally two square of paper combine;

Get square of paper 1, do two diagonal fold lines, intersect at square of paper 1 central point; By square of paper 1 central point, do two positive broken lines of the vertical line vertical with trimming, two positive broken lines of vertical line are mutually vertical;

Get square of paper 2, do two positive broken lines of diagonal, intersect at square of paper 2 central points; By square of paper 2 central points, do two vertical line fold lines vertical with trimming, two vertical line fold lines are mutually vertical;

Square of paper 2 is placed on square of paper 1, square of paper 1 central point overlaps as coincidence central point with square of paper 2 central points, diagonal fold line overlaps with vertical line fold line as coincidence fold line, and the positive broken line of vertical line overlaps with the positive broken line of diagonal as the positive broken line that overlaps; Outside square of paper 1 and square of paper 2 laps, be eight congruent isosceles triangles, wherein the isosceles triangle of four square of paper 1 is that the isosceles triangle of 1, four square of paper 2 of isosceles triangle is isosceles triangle 2; The base of isosceles triangle 1 intersects at isosceles triangle 1 base intersection point with the fold line that overlaps; Do isosceles triangle 2 base fold lines on the base of isosceles triangle 2;

According to isosceles triangle 2 base fold lines, isosceles triangle 2 is folded and is affixed, with the overlapping square of square of paper 1 congruence; In coincidence fold line, get the end points of coincidence fold line to i.e. 1/2 mid point in 1/2 place of the central point that overlaps; Two end points in isosceles triangle 2 base fold lines do short fold line respectively and between 1/2 nearest mid point; The base of isosceles triangle 1 and nearest two short fold lines form isosceles triangles 3; Between 1/2 mid point and isosceles triangle 1 base intersection point, do tangent line, isosceles triangle 3 is divided into two congruent isosceles triangles 4 by tangent line; Tangent line is the otch cutting;

According to short fold line, isosceles triangle 4 is folded in the interlayer between square of paper 1 and square of paper 2;

Folding according to overlap positive broken line and coincidence fold line, be formed with four folding leg-of-mutton solid figures; Folding leg-of-mutton short fold line is divided into double-deck miter angle, i.e. insertion portion to square of paper 1 paper bight; The short fold line on folding triangle two sides is the socket that is inserted into part, is inserted into socket; An assembly completes;

The insertion method of two assemblies; The folding sub-fraction of wedge angle of insertion portion, folded part is no longer than 1/3 of insertion portion length, folding direction be not with the one side that is inserted into socket and fits, by 2 one folding leg-of-mutton sockets that are inserted into of the insertion portion plug-in package of 1 one triangles of assembly, meanwhile, assembly 2 is inserted into same folding leg-of-mutton being inserted in socket of same folding leg-of-mutton insertion portion plug-in package 1 insertion portion of socket;

The short fold line of insertion portion overlaps with the short fold line that is inserted into jack part, and two assemblies complete grafting;

With same insertion method, a folding triangle of do not peg graft folding triangle and the assembly 3 of assembly 2 plugs, and another folding triangle of assembly 3 and a folding triangle of assembly 4 plug, and peg graft in this way, and assembly 4 plugs with assembly 5; Assembly 5 plugs with assembly 1, a pentagonal sealing ring;

Outside pentagon sealing ring, two plug the folding triangle of not pegging graft that assembly is adjacent and can peg graft into a triangle sealing ring with two folding triangles of another assembly;

Each pentagon sealing ring is outer can adjacent peg graft into five triangle sealing rings; Each triangle sealing ring is outer can three pentagon sealing rings of adjacent grafting; Peg graft in this way, 30 modular connector Cheng Zhengyuan fancy balls.

The invention has the beneficial effects as follows, establishment of component is simple, pegs graft easily; Exotic shape is well-pressed attractive in appearance; Insertion portion makes fancy ball more firm with the locking function that is inserted into part.
