Claims

[Claims for Utility Model Registration] A cylindrical convex surface 4 having a cylindrical shape is provided on the block side surface ₂₁ , which is one surface of a cylindrical column or a rectangular cylindrical column block 1. A plurality of L-shaped notches 5 are provided along the block side surface ₂₁ , and further cut in an L shape to the outer periphery of the block side surface ₂₁ in the radial direction, and a plurality of convex portions are formed around the block side surface ₂₁ . A cylindrical concave surface 8 having a cylindrical shape is provided on the block side surface ₂₂ on the opposite side, and a convex portion 7 or a concave portion _{9 provided on the block side surface 21} _around the block side surface 22.
A plurality of convex portions 7 or concave portions 9 are provided at positions corresponding to the cylindrical concave surface 8, and the cylindrical convex surface 4 of another block 1 is fitted into the cylindrical concave surface 8 so that the mutual blocks 1 can rotate around the cylinder, A rotating block connected to a circular cylinder and a square cylindrical column, in which a convex portion 7 and a concave portion 9 provided on the block sides 2 ₁ and 2 ₂ can be attached and detached at the same time at the rotation position.
