Board-Carrying Support device and Manufacturing Method Thereof

A manufacturing method of board-carrying support device, comprising steps of:

• forming a supporting frame through affixing at least two frame bars on a plane, the supporting frame comprising a bottom panel;
• arranging at least two fixed angle platforms on the bottom panel, the at least two fixed angle platforms are spaced apart from each other;
• arranging a pivot in a form of a shaft hole or a shaft arm on a bearing board;
• rotatably connecting a first end of a spacing frame with a back side of said bearing board;
• and
• pivotally mounting said bearing board to an inner side of said supporting frame by means of said pivot such that said bearing board is pivotable to a side of a reference plane where said supporting frame is located, such that said bearing board is pivotably movable between a collapsed state and an inclined state, wherein in said collapsed state, the bearing board is maintained parallel to said reference plane, wherein in said inclined state, said bearing board is maintained in an inclination angle that an included angle between said back side of said bearing board and said reference plane is less than 90 degrees, and a second end of said spacing frame is abutted against at least one of said at least two fixed angle platforms, so that side included angle between said back side of said bearing board and said reference plane is fixed.
