Fastening device and a computer case having the fastening device

A computer case having a fastening device, comprising:

• a positioning frame adapted for accommodating an electronic device that has a side face formed with two blind holes spaced apart from each other, said positioning frame having a side wall, said side wall of said positioning frame having an outer face and being formed with two holes disposed at positions respectively corresponding to the two blind holes;
• and
• a fastening device provided on said side wall of said positioning frame for fastening of the electronic device, said fastening device including
• a limiting component disposed between said two holes and including a connecting part connected to said outer face of said side wall of said positioning frame, and a limiting part extending from said connecting part and spaced apart from said side wall of said positioning frame, said limiting component being in a form of a hook with an opening and to be disposed at a location that is offset in a direction toward said opening from an imaginary line interconnecting the two blind holes,
• a positioning component including an elongated rod body having two ends, and two positioning parts extending respectively from said two ends of said rod body, each of said positioning parts extending from said outer face of said side wall of said positioning frame into a respective one of said two holes and a respective one of the two blind holes, said rod body being limited from movement in a direction away from said side wall of said positioning frame by said limiting part of said limiting component;
• and
• a pull component connected to said rod body of said positioning component and disposed at a position that is staggered with a position of said limiting component, said pull component is in a shape of a thin plate that has an upper end and a lower end and that is fastened to said rod body via surrounding said rod body and adhering said upper end to said lower end;
• wherein, by virtue of the offset arrangement between said limiting component and said blind holes, said positioning component presents a curved shape when said positioning component is disposed on said positioning frame due to a distance between said limiting component and the imaginary line, so that said rod body provides an upward force applied to said limiting component and said positioning parts of said positioning component provide downward forces applied to said blind holes, the downward forces cooperating with an upward supporting force provided by said positioning frame so as to achieve a clamping effect for securely fastening the electronic device.
