Abstract: The first fastener comprises a post, a fifth outer boss, an outer slab, a first hole and a second inner flange. The fifth outer boss is provided in an upper portion of the post. The outer slab perpendicular to the post is provided in a lower portion of the post. The first hole is provided within a local region of the outer slab below the post. The second inner flange is provided on an inner wall of the first hole. The second inner flange has a first gap greater than a width of the fifth outer boss. The upper surface of the second inner flange is used for abutting on a lower surface of a fifth outer boss of a second fastener having a same structure as the first fastener when limiting a position of connected pieces in a height direction of the post. Two sections of the second inner flange and two sections of the first gap are provided on the inner wall of the first hole in a staggered manner. Each section of the second inner flange is equivalent to ¼ of a circumference of the inner wall of the first hole.

Abstract: A fastener connecting member suited with a fastener, comprising a third through hole and a plurality of third inner flanges. The fastener includes a post. A plurality of third inner flanges used for being clamped by the adjacent outer bosses of the fastener are provided on an inner wall of the third through hole at different heights. An upper surface and a lower surface of each of the third inner flanges form a wedge in a plane of the axis of the post. The third inner flanges are coordinated with adjacent outer bosses to realize radial positioning of the fastener connecting member and the fastener.

Abstract: The device is combination of a fastener and a splicing piece suited with the fastener. The fastener includes a post, a plurality of outer bosses, an outer slab, a first hole and a second inner flange. The plurality of outer bosses are provided in an upper portion of the post. The plurality of outer bosses include a first outer boss, a second outer boss and a third outer boss. The first outer boss is located under the second outer boss. At least a local portion of the splicing piece is a platy portion. Connecting through holes are provided in the platy portion. The connecting through holes include a first through hole. A first inner flange used for being clamped by a lower surface of the first outer boss and an upper surface of the second outer boss is provided on an inner wall of the first through hole.

Abstract: A splicing piece suited with a fastener. The fastener comprises a post. At least one local portion of the splicing piece is a platy portion. Connecting through holes are formed on the platy portion. The connecting through holes comprise a first through hole.
