A fastening device is provided on a side wall of a positioning frame for fastening of an electronic device disposed in the positioning frame. The fastening device includes a limiting component and a positioning component. The limiting component includes a connecting part connected to an outer face of the side wall, and a limiting part extending from the connecting part and spaced apart from the side wall. The positioning component includes a rod body, and two positioning parts extending respectively from two ends of the rod body. Each of the positioning parts extends into a respective one of two holes in the side wall and a respective one of two blind holes in the electronic device. The rod body is limited from movement in a direction away from the side wall by the limiting part.

1. A fastening device adapted to be provided on a side wall of a positioning frame for fastening of an electronic device disposed in the positioning frame, the electronic device having a side face formed with two blind holes spaced apart from each other, the side wall of the positioning frame having an outer face and being formed with two holes disposed at positions respectively corresponding to the two blind holes, said fastening device comprising: a limiting component to be disposed between the two holes and including a connecting part to be connected to the outer face of the side wall of the positioning frame, and a limiting part extending from said connecting part and to be spaced apart from the side wall of the 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 being adapted to be extended from the outer face of the side wall of the positioning frame into a respective one of the two holes and a respective one of the two blind holes, said rod body being limited from movement in a direction away from the side wall of the 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. 2. The fastening device as claimed in claim 1, wherein said limiting component is to be disposed closer to one of the two holes compared to said pull component, and said pull component connected to said rod body of said positioning component is to be disposed closer to the other one of the two holes compared to said limiting component. 3. The fastening device as claimed in claim 2, wherein said limiting part of said limiting component has a free end distal from said connecting part, and said limiting component further includes a guiding part extending outwardly and obliquely from said free end of said limiting part. 4. The fastening device as claimed in claim 1, wherein said positioning component is formed integrally by bending a metal wire section. 5. The fastening device as claimed in claim 1, wherein said limiting component is formed integrally by cutting the side wall of the positioning frame, followed by bending a cut section of the side wall. 6. 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; anda 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; anda 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. 7. The computer case as claimed in claim 6, wherein said limiting component is disposed closer to one of said two holes compared to said pull component, and said pull component connected to said rod body of said positioning component is disposed closer to the other one of said two holes compared to said limiting component. 8. The computer case as claimed in claim 7, wherein said limiting part of said limiting component has a free end distal from said connecting part, and said limiting component further includes a guiding part extending outwardly and obliquely from said free end of said limiting part. 9. The computer case as claimed in claim 6, wherein said positioning component is formed integrally by bending a metal wire section. 10. The computer case as claimed in claim 6, wherein said limiting component is formed integrally by cutting said side wall of said positioning frame, followed by bending a cut section of said side wall.
