Embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described further：

, it is necessary to explanation in description of the present utility model, term " " center ", " on ", " under ", it is "left", "right", " perpendicular Directly ", the orientation of the instruction such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only Described for the ease of description the utility model and simplifying, rather than instruction or imply signified position or element must have it is specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.

, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, It can be the connection of two element internals.For the ordinary skill in the art, it is above-mentioned that concrete condition understanding can be regarded Concrete meaning of the term in the utility model.
