Patent ID: 8705250

Claim:
A fixing mechanism for fixing at least one interface card having a bending board, the fixing mechanism comprising: a casing for containing the interface card; a bracket structure disposed at a side of the casing corresponding to the interface card and having a positioning member and a pivot member, the bracket structure further having a support surface for supporting an end of the bending board; and a fixing rod movably disposed on the bracket structure, the fixing rod comprising: a clamping portion for clamping an the end of the bending board cooperatively with the bracket structure when moving to a fixing position; a hook portion connected to a first end of the clamping portion for hooking the positioning member when the clamping portion moves to the fixing position; and a torsion-spring portion connected to a second end of the clamping portion and pivotally connected to the pivot member so as to make the clamping portion and the hook portion capable of rotating parallel to the support surface to the fixing position overlapping with the end of the bending board or rotating parallel to the support surface to a releasing position not overlapping with the end of the bending board, the torsion-spring portion being used for driving the clamping portion to the releasing position to separate the clamping portion from the end of the bending board.
