When the outer surface of the fixing member 3 encounters the inner surface of the movable member 42, the movable member 42 stops moving. Since the antenna body 1 is fixed to the movable member 42, It can move as the movable member 42 moves. When the movable member 42 is in the folded state, the baffle 420 of the movable member 42 and the front end surface of the fixing member 3 are in the same plane. However, the baffle 420 of the movable member 42 may exceed the bottom plate 33 of the fixing member 3 for convenient hand grasping. . The fixing member 3 is mounted in the receiving slot of the portable electronic device housing, and the button 6 is exposed outside the receiving slot of the portable electronic device housing for convenient operation.

Whether in the collapsed state or the open state or the intermediate state between the two, the torsion spring 5 is always squeezed between the movable member 42 and the fixed member 3 to provide at least a partial opening force of the movable member 42.

The top plate 34 of the fixing member 3 and the bottom plate 33 are thinner and more elastic than the side walls 31, 32, and can provide large deformation in the vertical direction, and the movable member 42 accommodated therein can be moved up and down to get rid of the interference block 311. Interference can be removed from the fixture 3 without damage.

In use, the antenna body 1 of the antenna assembly 100 can be pulled out of the design of the portable electronic device such that the interference of the internal components of the portable electronic device to the antenna body 1 is reduced, thereby making the radiation performance better.
