Adopt above-mentioned further scheme's beneficial effect to be, through setting up the fixed part, can be convenient for fix each shell alone.

Further, a magnet is provided inside each fixing portion.

Adopt above-mentioned further scheme's beneficial effect is, through setting up magnet, can adsorb two shells each other to be convenient for accomodate, avoid the electric wire to twine each other.

Furthermore, the bottoms of two adjacent shells are respectively provided with a corresponding boss and a corresponding groove.

The beneficial effect who adopts above-mentioned further scheme is that, through setting up boss and recess, can improve the stability after two shells adsorb each other, make it be difficult to drop.

For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.
