This utility model discloses a building block and track building block toy including four of single components and eight of magnetic spheres; each one of single components comprises a first connecting rod, a second connecting rod and a third connecting rod; the first connecting rod, the second connecting rod, and the third connecting rod are sequentially connected to form a “” shape; a first insertion portion is disposed on an end of the first connecting rod, and another one of first insertion portion is disposed on an end of the third connecting rod; second insertion portions extend vertically at both ends of the second connecting rod; each of the second insertion portions is provided with one of inserting holes. A plurality of the building blocks are able to be adsorbed together by magnetic spheres and assembled into various shapes.

1 . A building block, comprising:
 four of single components and eight of magnetic spheres;   each one of single components which comprises a first connecting rod, a second connecting rod and a third connecting rod;   the first connecting rod, the second connecting rod, and the third connecting rod sequentially connected to form a “ ” shape;   a first insertion portion disposed on an end of the first connecting rod, and another one of first insertion portion disposed on an end of the third connecting rod;   second insertion portions which extend vertically at both ends of the second connecting rod;   each of the second insertion portions provided with one of inserting holes;   in use, the two of the first insertion portions and of each of the single components inserted into the inserting holes of the two of the second insertion portions of the other single components one by one, so that the four of the single components are assembled to cube shape;   all the magnetic spheres pressed into the inserting holes of the second insertion portions one by one.   
     
     
         2 . The building block according to  claim 1 , wherein lengths of the first connecting rod, the second connecting rod and the third connecting rod are equal, and the four of the single components are assembled into a cube shape. 
     
     
         3 . The building block according to  claim 1 , wherein the inside of each inserting holes is provided with an undercuts;
 the magnetic spheres are pressed into the inserting holes and are fixed by the undercuts, so that the magnetic spheres are not able to come out of the inserting holes.   
     
     
         4 . The building block according to  claim 3 , wherein the undercut is integrally formed on the inner walls of the inserting holes. 
     
     
         5 . The building block according to  claim 1 , wherein at least one of the first connecting rod, the second connecting rod, and the third connecting rod is provided with a plurality of spacers distributed at intervals, and every two adjacent ones of the spacers form one of the clamping slots. 
     
     
         6 . A track building block toy, comprising
 a plurality of building blocks according to any one of  claim 1 ;   wherein all the building block are able to be adsorbed by the magnetic spheres and stacked together;   bottom of each of the tracks is provided with a plurality of insertion portions;   the tracks are inserted and fixed to the building blocks through the insertion portions;   all the tracks are connected in turn and meandering through the interior of each of the building blocks.   
     
     
         7 . The track building block toy according, to  claim 6 , wherein at least one of the first connecting rod, the second connecting rod, and the third connecting rod is provided with a plurality of spacers, and the clamping slots are formed between adjacent ones of the spacers of the building blocks;
 each of the insertion portions of the tracks is correspondingly inserted into the clamping slots of the building blocks.   
     
     
         8 . The track building block toy according to  claim 6 , wherein the track building block toy also comprises at least one of insertion board frames, and each of the insertion board frames is placed on top of one of the building block blocks;
 the insertion board frames are rectangular, and the four sides of the insertion board frames are provided with a plurality of spacers distributed at intervals, so that clamping slots are formed between every two adjacent ones of the spacers for the fixation of the insertion portions of the tracks, so that at least one section of the tracks is mounted on the top of the insertion board frames.   
     
     
         9 . The track building block toy according to  claim 8 , wherein the heights of the multiple ones of the insertion portions at the bottom of the tracks on the top of the insertion board frames are also different, so that the heights of the tracks gradually decreases from one end to the other end. 
     
     
         10 . The track building block toy according to  claim 8 , wherein the track building block toy also comprises a ball launcher, which is disposed inside one of the building blocks and is communicated with the tracks.
