In at least one embodiment, the shape of the first conductive portion 5311 can be changed as needed, for example, when the display 30 needs to be rotated 260 degrees around the first axis “o”, the fan-shaped surface rotates 260 degrees around the first axis “o” and forms the first conductive portion 5311. In at least one embodiment, the bushings 551, the resisting members 552, and the covers 553 can be omitted, the elastic members 554 can be fixed on the housing 51.
