     A transverse length of the iron tube is greater than that of the magnet. Specifically, the transverse, length of the iron tube is twice that of the magnet. 
     By means of the above structure, the magnetic attraction member can be exposed from the base and the cover body through the limiting gap. Compared with the prior art that a magnet is arranged in a′plastic shell and fails in direct contact such that the magnetism is lowered, the present disclosure achieves direct contact between magnetic attraction toys, thus enhancing the first stage of magnetic force. Furthermore, the magnetic attraction member includes the iron tube and the magnet located in the iron tube, so that the transverse length of the iron tube can be set to be greater than that of the magnet. Specifically, the transverse length of the iron tube can be set to be twice that of the magnet, and the first clamping end and the second clamping end can be inserted into two ends of the iron tube, so that a magnetic attraction contact area between, the magnetic attraction toys can be multiplied, and the magnet can still be fixed in a center position of the iron tube to provide a stronger and more stable magnetic attraction force, thus enhancing the second stage of magnetic force. In addition, the iron tube wrapping around the magnet makes magnetic induction lines around the magnet distributed intensively, so that the magnetic induction intensity around a surface of the magnetic attraction body becomes stronger, thus enhancing the third stage of magnetic force. A surface contact magnetic force of the magnetic attraction toy is enhanced by superposition of the enhancement of the three stages of magnetic forces, so that a user can put out a more three-dimensional, complicated and stable model using the magnetic attraction building blocks without increasing the cost for a strong magnet, and children&#39;s imagination can be developed more fully, which greatly increases the fun of experience of children. In addition, the first clamping piece and the second clamping piece are respectively clamped to two ends of the iron tube. On the one hand, the ribs welded with the first clamping piece and the second clamping piece are arranged on the base and the cover body, so that the number of welding lines is greatly increased, and a decrease in the quality of a product caused by difficulty in finding lack of weld is prevented. On the other hand, the thickness of an entire plastic building block is greatly increased, so that the overall torque resistance and tensile strength are greatly improved in order that children think a toy building block body cannot be broken with bare hands. A safety threat caused by the following fact can be effectively avoided: when playing the toy, a child swallows the magnet carelessly since a toy shell is broken. The safety of the magnetic attraction toy is then improved. Further, every country does not allow strong magnets to be exposed in children&#39;s products. The magnet is fixed in the iron tube. On the one hand, this regulation is met, and on the other hand, the magnetic attraction toys can be in direct contact through the surfaces of the iron tubes. Meanwhile, magnetic fields around the magnet are also strengthened. 
     In this embodiment, the base and the cover body can be provided with triangular, square, hexagonal, pentagonal, rhombus-shaped, trapezoid, fan-shaped or semicircular cross sections or cross sections in other shapes.
