a first section disposed along a length direction of the rotating shaft;
a second section disposed along the length direction;
a rotating shaft main body made of a metal material and comprising a side wall; and
an insulation material layer disposed around the side wall, wherein the insulation material layer and the rotating shaft main body jointly constitute the insulation part;

a first shaft sleeve constituting the first conductive part and sleeved on the first section in a fitted manner; and
a second shaft sleeve constituting the second conductive part and sleeved on the second section in the fitted manner, wherein the first shaft sleeve and the second shaft sleeve are spaced from each other along an axial direction of the rotating shaft;
a keyboard host comprising:
a first metal housing coupled to the second conductive part; and
a keyboard host edge proximate to the hinge;
a display screen rotatably coupled to the keyboard host through the hinge and comprising:
a second metal housing coupled to the first conductive part; and
a display screen edge proximate to the hinge;
a main radiating slot formed between the display screen edge and the keyboard host edge; an electrical connecting element passing through the main radiating slot to electrically couple the display screen to the keyboard host; a first ground member disposed in the main radiating slot; and a first feed member disposed in the main radiating slot, and disposed in a first second interval with the first ground member, wherein the first ground member is located between the first feed member and the electrical connecting element.

2 . The electronic device of claim 1 , wherein the hinge comprises a conductive material, and further comprises:
a first end coupled to the display screen and electrically coupled to the second metal housing; a second end coupled to the keyboard host and electrically coupled to the first metal housing; and the first ground member.

3 . The electronic device of claim 1 , wherein the first feed member is a conductive member disposed between the display screen and the keyboard host, and wherein the first feed member comprises:
