Device housing

A device housing, comprising:

• a first case, comprising a first protruding block, wherein the first protruding block comprises a first positioning hole;
• a second case, comprising a first groove, wherein the first groove comprises a second positioning hole, and when the first protruding block is disposed in the first groove, the first positioning hole is aligned to the second positioning hole;
• a first magnetically sensitive positioning pin, running through the first positioning hole and the second positioning hole, to position the second case on the first case;
• and
• a first compressible member, disposed in the first positioning hole, wherein the first compressible member is disposed between an inner wall of the first positioning hole and the first magnetically sensitive positioning pin, and when a first magnetic force is applied to the first magnetically sensitive positioning pin, the first magnetically sensitive positioning pin compresses the first compressible member and moves away from the second positioning hole.
