Abstract

A fastening device includes a head and a shank. The shank has opposite ends, one end of the shank is connected to the head, and the other end of the shank defines an operating part. The operating part is capable of cooperating with a disassembling tool to enable the fastening device to rotate with respect to the longitudinal axis of the shank.

Claims

1. A housing comprising:

a first housing defining at least one first through hole,

a second housing covering the first housing, the second housing having at least one fixing member, the at least one fixing member defining at least one second through hole, whereby when the second housing covers the first housing, a space inside the first and second housings is generally inaccessible from outside the first and second housings except via the first through hole and the second through hole; and

a fastening device located in the inaccessible space and having a head and a shank connected to the head, the shank having an operating part placed on one end of the shank and away from the head, wherein when the second housing covers the first housing, the at least one fixing member is positioned inside of the first housing, the shank is inserted into the at least one second through hole and the at least one first through hole in order, the operating part is capable of cooperating with a disassembling tool inserted into the through holes from outside the first and second housings to enter the inaccessible space and enable the fastening device to screw in the at least one first through hole.

2. The housing of claim 1, wherein the at least one first through hole is a threaded through hole.

3. The housing of claim 2, wherein the fastening device further comprises a screw thread wrapped around the shank.

4. The housing of claim 3, wherein the at least one second through hole is a threaded through hole, the fastening device can be screwed in the at least one second through hole before the second housing covers the first housing.

5. The housing of claim 3, wherein the at least one second through hole is a step hole, the at least one second through hole includes a larger hole and a small hole, the larger hole is capable of receiving the head, the small hole is a threaded through hole, the shank is screwed into the small hole.

6. The housing of claim 5, wherein the length of the screw thread taken along the longitudinal axis of the shank is the same as or shorter than the sum of the length of the small hole and the at least one first through hole.

7. The housing of claim 1, wherein the operating part is a blind hole defined on the other end of the shank, and runs along the longitudinal axis of the shank.

8. An electronic device comprising:

a first housing defining at least one first through hole,

a second housing covering the first housing, the second housing having at least one fixing member, the at least one fixing member defining at least one second through hole, whereby when the second housing covers the first housing, a space inside the first and second housings is generally inaccessible from outside the first and second housings except via the first through hole and the second through hole; and

a fastening device located in the inaccessible space and having a head and a shank connected to the head, the shank having an operating part placed on one end of the shank and away from the head, wherein when the second housing covers the first housing, the at least one fixing member is positioned inside of the first housing, the shank is inserted into the at least one second through hole and the at least one first through hole in order, the operating part is capable of cooperating with a disassembling tool inserted into the through holes from outside the first and second housings to enter the inaccessible space and enable the fastening device to screw in the first through hole.

9. The electronic device of claim 8, wherein the fastening device further comprises a screw thread wrapped around the shank.

10. The electronic device of claim 9, wherein the at least one second through hole is a threaded through hole, the fastening device can be screwed in the at least one second through hole before the second housing covers the first housing.

11. The electronic device of claim 10, wherein the at least one first through hole is a threaded through hole.

12. The electronic device of claim 10, wherein the at least one second through hole is a step hole, the at least one second through hole includes a larger hole and a small hole, the larger hole is capable of receiving the head, the small hole is a threaded through hole, the shank is screwed into the small hole.

13. The electronic device of claim 12, wherein the length of the screw thread taken along the longitudinal of the shank is the same as or shorter than the sum of the length of the small hole and the at least one first through hole.

14. The electronic device of claim 8, wherein the operating part is a blind hole defined in an end away from the head, and runs along the longitudinal axis of the shank.
