A splicing structure is disclosed, and the splicing structure includes at least two splicing blocks which are detachably spliced together, a splicing hole is arranged in one of the two splicing blocks which are spliced with each other, the other splicing block is provided with a splicing column which can be inserted into the splicing hole, and the splicing column is provided with an inner hole extending in an axial direction thereof. The splicing structure further includes: a plug piece having an insertion rod; a receptacle having a sleeve, where an insertion hole is formed on the sleeve.

A body of a mobility includes: a base part disposed outside a cabin room and extending in a longitudinal direction of the body, and including a first coupling surface; a fixed part extending in the longitudinal direction and coupled to the base part, and including a second coupling surface matching with the first coupling surface, the fixed part having an insertion hole being open toward one side thereof and extending in the longitudinal direction; and a pillar member having a first end inserted into the insertion hole of the fixed part to be coupled to the fixed part and a second end extended and being curved.

A container adapter includes a soft sleeve having a first and a second anti-slide sleeve portion; a rigid connecting pipe having a coupling portion, a stop portion and a plurality of slots. The first anti-slide sleeve portion is forward tapered, and the coupling portion is backward flared. The rigid connecting pipe is connected at the coupling portion to the first anti-slide sleeve portion of the soft sleeve with the stop portion abutted on a rim of the first anti-slide sleeve portion. To use the container adapter, simply fit the second anti-slide sleeve portion of the soft sleeve around an end of a container. Decorative accessories can be set in the slots to form ornaments, or pipes can be connected to the container adapter to form a fluid passage for guiding a liquid in the container, such that the container can have more applications and be advantageous to environmental protection.

Toy model assemblies of multiple planar layer pieces mechanically fastened together with adjustable connectors. Models incorporating the multilayered assemblies can be made to hold their position when the adjustable connectors are tightened. The layer pieces have profiles that represent specific model components some of which rotate about a perpendicular connector in parallel planes. Stratified layer assemblies capturing a specialized connector provide rotation on an axis in the same plane as capturing layers. The model layer pieces are preferably all the same thickness and cut from sheets of quality plywood.

A method and system of attaching rivets to secure sheets of paper together. The rivets have a head, a recess, a skirt and a tail. A tool is configured so that the tail fits through a hole in the tool. Before the tail is inserted into the hole in the tool, the tail is inserted through two holes in the paper(s) and then in the hole in the tool. Pressure is placed on the paper by pressing downward on the tool thereby causing the paper(s) to snap into the recess, thereby securing both pieces of paper together.

The invention relates to a toy building element for a modular building game. The toy building element comprises one or more hollow coupling studs for coupling the toy building element to another toy building element in a releasable manner. Each coupling stud extends along a respective longitudinal axis and defines internally an axial through cavity configured to receive, in a removable manner, a locking stud apt to lock the toy building element to another toy building element coupled thereto. Each coupling stud comprises a coupling part and a receiving part for receiving the coupling part of a coupling stud of another toy building element. The coupling part comprises at least a radially flexible portion for engaging/disengaging a receiving part of a coupling stud of another toy building element. The radially flexible portion is configured to cooperate with one said locking engaging the cavity so that its radial bending is limited by the locking stud so as to prevent the coupling part from disengaging from the receiving part of a coupling stud of another toy building element.

A construction kit enables building of complex structures. The kit can include pole connectors, along with a series of hubs. For instance, two-point hubs, four-point hubs, eight-point hubs, five-point hubs, six-point hubs, and a clip can be the constituent parts of the kit. Some of the hubs can be flexible to provide further utility and additional angles for building. Complex structures, such as a ball-shaped connector can also be achieved from the base components.

The building toy includes at least one basic element and at least one connecting pin. The basic element has a body where in the wall there is at least one connecting opening led perpendicularly onto the wall. The connecting opening runs through the body of the basic element as a transitory cavity and the connecting opening is designed for an insertion of the connecting pin. All connecting openings in the body are mutually spatially skew. The pairs of connecting openings from each wall run through the body to lie in mutually perpendicular and rotated planes and the distance of the connecting openings if each pair is identical and it is at least the length of a diameter of the connecting openings. The pairs in the central zone of the body avoid each other without the cavities of the connecting openings colliding mutually.

The invention relates to producing kits for games and souvenirs. The invention consists in a node for connecting moving elements thereof in order to perform a connecting action using two groups of components. A first group of components and a second group of components are connected by means of inserting protrusions, which are positioned along opposing edges of at least two individual components of the second group, in at least two rectangular connecting apertures of one of the individual components of the first group, and which are disposed symmetrically relative to a central aperture on each of the individual components of the first group. The second group of components contains at least two individual components which are made in the form of symmetrical pairs. The result consists in the fastest and most-reliable assembly of the node.

Interlocking panels are assembled to form modules, and the modules are assembled to form a modular display case, for displaying, transporting and storing objects such as models, display items or valuable collectibles. The interlocking panels include interlocking side edge ball key tab including a resilient, compressible ball key, and ports for removably receiving the ball key tab and ball key.
