Claim:
1. A device for one or more toy blocks, the device comprising a plurality of main unit bodies each having a same structure, a same shape and a same volume, wherein: each of the plurality of main unit bodies is a tetradecahedron having six square surfaces and eight regular hexagon surfaces, the six square surfaces are averagely divided into three groups, two square surfaces in a group of the three groups are parallel, the eight regular hexagon surfaces are averagely divided into four groups, two regular hexagon surfaces in a group of the four groups are parallel, more than two main unit bodies are mutually spliced or fixedly connected to constitute a group, or a combination thereof, a column head is located on at least one of square surfaces on each of main unit bodies, the column head is located on a same axis of another square surface, column heads of each of two main unit bodies are mutually coordinated with a slot, or the column heads of each of two groups of main unit bodies are mutually coordinated with a slot, a component comprises two or more main unit bodies of the plurality of main unit bodies in a same group through connection and fixation that comprises a combined body, and wherein the column head comprises a square column, a frustum and a cylinder through connection, the square column is vertically connected with the square surface, the square column is connected with the cylinder through the frusta, the side length of the square column is greater than the diameter of the cylinder; small particle double-row four combined body are installed in the periphery of the frusta, the small-particle double-row four combined body comprises four small main unit bodies which are connected in two lines and two rows, the small main unit bodies have the same shape and structure as those of the main unit bodies, and the dimension of the small main unit bodies is one-half of that of the main unit bodies, and the square hole enclosed by four main unit bodies are coordinated with the frusta, and the diameter of the cylinder is equal to the diameter of the column head of the small unit bodies.
