Node of individual moving elements of mechanical model

A unit of separate moving elements of a mechanical model, which are able to rotate around a single axis, that comprises

• the axis, the separate moving elements and parts of such separate moving elements connected to each other, and differs in that it comprises
• a first group of parts and a second group of parts, herewith the first group of parts comprises at least two separate parts, and each of these separate parts of the first group of the parts comprises a central axle hole for insertion the axis into it;
• besides this, each of at least two separate parts of the first group comprises at least two rectangular connecting holes, which are disposed symmetrically in relation to the center hole on each of the separate part of the first group, while the second group of the parts comprises at least two separate parts which are pairwise symmetric, and each of these separate parts of the second group comprises protrusions at opposite edges;
• besides this, each of these separate parts of the second group comprises at least one central protrusion in each central section, herewith the first group and the second group of parts are interconnected by means of separate parts of the second group, which are pre-grouped and form a central axial clearance between the central protrusions of these separate parts of the second group, as well as while connecting the parts of the first and second groups, the protrusions disposed on one side at the edges of separate parts of the second group are inserted into at least two rectangular connecting holes of one of the separate parts of the first group, and other protrusions, which are disposed from the other side at the edges of separate parts of the second group, are inserted into at least two rectangular connecting holes of another separate part of the first group, and the axis is inserted into a central hole of one of the separate parts of the first group and into the central axial clearance formed between the central protrusions of the separate parts of the second group, as well as into the central hole of the other separate part of the first group.
