It will be appreciated that it is also possible to provide a further first coupling element 20 on the second coupling arm 12, by means of which first coupling element 20 it cooperates with another toy building element; alternatively, a second connector 60 may be provided on the second connector arm 12 for mating with the first connector 20 to effect mating with the toy building element thereof. As shown in fig. 5, a toy building element cooperating with the toy building element provided in this embodiment comprises a connection body 63 and a second connection piece 60 arranged on the connection body 63; the shape of the connection body 63 may be determined according to the design requirements of the product. The second connection member 60 includes a connection post 62 and a connection pad 61 connected to the connection post 62. Specifically, the connection disc 61 is square, and the connection post 62 may be a cylinder or a quadrangular prism; the connection disc 61 and the connection post 62 are coaxial and arranged in a T-shape. The connecting post 62 of the second connecting piece 60 is provided with a limiting clamping groove 41, and one end of the connecting post 62, which is close to the connecting disc 61, is provided with a second chamfer 621.

In the present embodiment, as shown in fig. 1 to 3, the two first connecting members 20 include a left side plate 21, a right side plate 22, a rear side plate 23, a bottom plate 24, and a top plate 25 which are integrally formed; and the outer surfaces of the two top plates 25 are flush with the inner surfaces of the first connecting arms 11. It will be appreciated that another toy building element provided with a second connector 60 can be placed in the element body 10 in a U-shaped arrangement, which is to be fitted with the first connector 20 on the first connector arm 11, so that the toy building element can be fitted with other toy building elements to meet its specific functional requirements. For example, a toy building element provided with a second coupling member 60, the coupling post 62 of which can rotate relative to the coupling body 63, and the height of the coupling body 63 matches the distance between the first coupling arm 11 and the third coupling arm 13, is arranged in the element body 10, such that the second coupling member 60 cooperates with the first coupling member 20, thereby enabling the toy building element to rotate relative to the toy building element provided in this embodiment, satisfying its design requirements.

Specifically, the positioning post may be a connection pin that mates with the connection hole 50 on the third connection arm 13, and the connection pin protrudes slightly from the inner surface of the third connection arm 13. When the toy building element is fitted with two other toy building elements (the first coupling piece 20 is provided on the coupling body 63 and the first coupling piece 20 is rotatable), the positioning post corresponds to a rotational axis to meet design requirements.

The left side plate 21, right side plate 22, rear side plate 23, bottom plate 24 and top plate 25 are of hexahedral design and cooperate to form a receiving recess 30 for the insertion of a second connector 60 of another toy building element. It can be appreciated that the first connecting member 20 is provided with openings of the receiving grooves 30 on a surface opposite to the rear side plate 23, and the openings of the two receiving grooves 30 are in the same direction. In the embodiment, the bottom plate 24 and the top plate 25 are square, so that when a plurality of toy building elements are built, the influence on toy building caused by inconsistent side lengths is avoided, and the user experience is improved; and, the four corner edges may be designed in an arc shape, so that the appearance of the first connecting piece 20 is smooth and beautiful.

As shown in fig. 3, the receiving groove 30 includes a disc groove 31 for receiving the connection disc 61 and a column groove 32 for receiving the connection column 62, and is provided in an inverted T shape, and in order to secure the tightness of the connection, the size of the disc groove 31 is matched with the size of the connection disc 61 of the second connection member 60; the size of the post recess 32 matches the size of the connecting post 62 of the second connector 60. The inner walls of the bottom plate 24, the top plate 25, the left side plate 21, the right side plate 22, and the rear side plate 23 cooperate to define a plate slot 31 for receiving the connecting plate 61. The top plate 25 is provided with a column groove 32. Specifically, the top plate 25 includes an integrally formed top plate left portion 251, top plate rear portion 253, and top plate right portion 252, with the inner side walls of the top plate left portion 251, top plate rear portion 253, and top plate right portion 252 defining a column slot 32 for receiving the connecting column 62. In this embodiment, the distance between the left top plate 251 and the right top plate 252 is identical to the diameter of the cylindrical connecting post 62, so that the post slot 32 is more tightly matched with the connecting post 62, and is not easy to fall off.
