The number of the matrix hole profiles 1 is at least two, at least two matrix hole profiles 1 can form a frame structure, and referring to fig. 3, in this embodiment, by longitudinally placing one round through hole matrix hole profile with a side matrix of 2X3, and transversely placing one round through hole matrix hole profile with a side matrix of 2X6, the description is given. The two matrixes Kong Xingcai are mutually matched and fixed by the end plate 2, the bushing 3, the fastening rod 6 and the fastening bolt.

The end plate 2 is a cuboid with a square end surface, the end surface of the end plate 2 is also provided with round through holes, the number of the round through holes is 2X2, four round through holes are respectively formed in four corners of the end plate, the thickness of the end plate 2 is identical to the depth of the end plate groove 5, and when the end plate 2 is placed in the end plate groove 5, the end surface of the end plate 2 and the end surface of the matrix Kong Xingcai are at the same horizontal height.

The bushing 3 is a hollow cylinder provided for allowing the fastening bolt to pass through. The number of the bushings 3 is set based on the number of the round through holes of the end plate 2, and the number of the round through holes cannot be exceeded, but cannot be reduced by two. The diagonally arranged bushings can prevent the two matrix hole patterns from being displaced in a translational manner. It should be noted that the inner diameter of the circular through hole is the same as the outer diameter of the bushing, and further, in order to realize the modularization, the circular through holes are all the same.
