Claims

1. An electronic device, comprising:

2. The electronic device of claim 1, the body having a first functional means;

3. The electronic device of claim 1, the first and second supports being symmetrically arranged with respect to the body;

4. The electronic device according to claim 3, wherein the first shielding portion is an arc-shaped shielding plate extending along a rotation path of the first support body relative to the first end, and is arranged on a front shell of the first end far away from the exit surface;

5. The electronic device of claim 1, said first pivot means creating a first torsion between said first support and said first end operable to maintain a relative relationship of said body and said viewer's head in said first positional relationship;

6. The electronic device of claim 5, wherein in the second positional relationship, the first torsion shaft device generates a second torsion force between the first support and the first end to maintain the first support in the second positional relationship;

the second torsion force is smaller than the first torsion force.

7. The electronic device according to claim 6, wherein the elastic member is extended and contracted in a direction of a rotation axis of the first spindle device.

8. The electronic device of claim 7, wherein the first spindle means comprises:

the first support is fixedly connected with the first support body;

the second bracket is fixedly connected with the body;

9. The electronic device of claim 6, wherein the elastic member extends and contracts along a direction in which the first end points to the first support body;

10. The electronic device of claim 9, wherein the first spindle means comprises:

the rotating shaft is fixed on the body;
