Patent ID: 8020823

Claim:
A three-dimensional multi-directional rotation support, comprising: a fixation base comprising a first plate having two opposite end edges extended to form a first extension plate, respectively, wherein each of the first extension plates is extended away from one side surface of the first plate, bent at a first angle in relation to the first plate, and then extended to form a first parallel portion, wherein both of the first parallel portions are parallel to each other, and each of the first parallel portions is formed with a first pivot hole which has a plurality of positioning points radially and equidistantly formed on a periphery thereof; a first connection base comprising a second plate formed with a first connection hole which has a plurality of positioning points radially and equidistantly formed on a periphery thereof; wherein two opposite end edges of the second plate are extended to form a second extension plate, respectively, wherein each of the second extension plates is extended away from one side surface of the second plate, bent at a second angle in relation to the second plate, and then extended to form a second parallel portion, wherein both of the second parallel portions are parallel to each other, and each of the second parallel portion is formed with a second pivot hole which has a plurality of positioning points radially and equidistantly formed on a periphery thereof; wherein an outer or inner side surface of each of the second parallel portions is attached to a corresponding inner or outer side surface of each of the first parallel portions, while a first screw assembly passes through the second pivot holes and the first pivot holes to pivotally connect the second parallel portions with the first parallel portions, and wherein the positioning points of the second parallel portions are engaged with the corresponding positioning points of the first parallel portions; and a second connection base comprising a third plate formed with a second connection hole which has a plurality of positioning points radially and equidistantly formed on a periphery thereof; wherein a second screw assembly passes through the second connection hole and the first connection hole to pivotally connect the third plate with the second plate, while the positioning points of the third plate are engaged with the corresponding positioning points of the second plate; wherein two opposite end edges of the third plate are extended to form a third extension plate, respectively, wherein each of the third extension plates is extended away from one side surface of the third plate, bent at a third angle in relation to the third plate, and then extended to form a third parallel portion, wherein both of the third parallel portions are parallel to each other, and each of the third parallel portion is formed with a third pivot hole which has a plurality of positioning points radially and equidistantly formed on a periphery thereof.
