The bottom of the described shaft of a writing brush is provided with reducing.

The described cap for brush is threaded with the shaft of a writing brush.

Described hinge is provided with groove, and described positioning seat is located by connecting by this groove and rotating shaft.

Described hinge connector is provided with raised step.

The top of described hinge is provided with step.

Shell fragment in the described rotating shaft is the cydariform shell fragment.

Compared with prior art, the utility model is rational in infrastructure, uses U-shaped spring location, has the following advantages:

1. can increase effective antenna length, improve radio-frequency performance;

2. the cap for brush and the shaft of a writing brush can be fixed, and when doing the writing pen use, antenna part is not unfolded;

3. the connect-disconnect life height of antenna;

4. the use feel of antenna as snug as a bug in a rug.
