Through adopting above-mentioned design to make the forced induction structure in this application only can be triggered when the pressure-bearing surface 520 on the shell 500 is pressed to the user, also can trigger the forced induction structure when having avoided the user to touch other surface adjacent with pressure-bearing surface 520 on the shell 500 by mistake, is favorable to realizing the accurate trigger of forced induction structure, has improved user's use experience.

The foregoing description of the preferred embodiment of the present utility model is not intended to limit the utility model to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
