360 degree folding jig

A folding jig, comprising:

• a fixed plate module on which a first side of a sample is supported;
• a folding plate module that is spaced apart from the fixed plate module and on which a second side of the sample is supported such that the second side of the sample is capable of being in-folded and out-folded with respect to the first side of the sample;
• and
• a pair of rotation support modules respectively provided at each end of the mutually adjacent fixed plate module and the folding plate module, and configured to couple the folding plate module to the fixed plate module so that the folding plate module is in-folded or out-folded,
• wherein the rotation support modules include:
• a first shaft forming an axis of rotation of the folding plate module with respect to the rotation support modules;
• and
• a second shaft that is spaced apart from the first shaft toward the fixed plate module and forms an axis of rotation of the rotation support modules with respect to the fixed plate module,
• wherein the rotation support modules rotate with respect to the fixed plate module in connection with a rotation of the folding plate module with respect to the rotation support modules when the folding plate module is in-folded or out-folded with respect to the fixed plate module, and
• wherein the folding plate module comprises:
• a guide panel to which the rotation support modules are coupled at each end in a state spaced apart from the fixed plate module, wherein the guide panel includes a reciprocating guide formed along a moving direction perpendicular to an imaginary line connecting the pair of rotation support modules;
• a reciprocating slider arranged to be reciprocally movable on the reciprocating guide;
• a reciprocating member coupled to the reciprocating slider from a first side of the guide panel and supporting the second side of the sample;
• and
• a reciprocating support member coupled to the reciprocating slider from a second side of the guide panel.
