Accompanying drawing 3 is the exploded schematic view of the utility model.

Detailed ways:

See the accompanying drawings 1, 2, and 3 for the embodiment, which includes a turntable bottom shell 1, a rotating cover 2, and a turntable 3. A winding groove 4 is formed on the turntable 3, and a positioning mechanism 5 is formed on the turntable 3. The turntable 3 passes through the positioning mechanism. 5 is set in the cavity of the turntable bottom shell 1, and a spring is installed between the turntable 3 and the turntable bottom shell 1. Of course, other elastic parts can also be used instead of the spring, as long as the purpose of resetting the rotated turntable 3 is achieved. That's it.

Two limit steps 6 are formed on the turntable 3, and a limit rod 8 is hinged on the bottom shell 1 of the turntable. The limit rod 8 is located on the outer edge of the turntable 3, and one end of the limit rod 8 is connected to the The limit step 6 abuts against the fit, and the other end of the limit rod 8 is press-fitted with the button 7 hinged on the bottom shell 1 of the turntable; a spring 9 is installed on the limit rod 8, and the spring 9 forces the limit rod One end of 8 presses the outer edge of the turntable 3, and the spring 9 makes the limit lever 8 always press against the outer edge of the turntable 3. As long as the limit step 6 of the turntable 3 reaches the position where the limit lever 8 is located, the limit lever 8 That is, it is automatically snapped into the limit step 6.

The rotating cover 2 is pivotally connected to the bottom shell 1 of the turntable, and the rotating cover 2 can rotate around its pivoting axis, so that an opening is exposed between the rotating cover 2 and the bottom shell 1 of the turntable, which is convenient to take out and store in the cavity of the bottom shell 1 of the turntable. headphone head 11 .

The connecting wire 10 of the earphone is wound in the winding groove 4 of the turntable 3 .

The earphone head 11 of the earphone is accommodated in the cavity of the turntable bottom shell 1 . Unscrew the rotating cover 2 to take out the earphone head 11 for use, lightly pull the connection line 10 to drive the turntable 3 to rotate, so that the connection line 10 can be pulled out from the winding slot 4 of the turntable 3, the signal input plug of the earphone 12 is connected through the through hole on the bottom shell 1 of the turntable, and the signal input plug 12 is located outside the bottom shell 1 of the turntable; a jack 13 for the signal input plug 12 is formed on the bottom shell 1 of the turntable.
