Fig. 2 be another visual angle in Fig. 1 partly cut open perspective view.
Fig. 3 is the overall appearance structural representation of Fig. 1.
Detailed description of the invention
In description of the present utility model, it is to be understood that " " center ", " on ", D score in term, "front", "rear",
Orientation or the position relationship of the instruction such as "left", "right" are based on orientation shown in the drawings or position relationship, are for only for ease of and retouch
State this utility model and simplifying describe rather than instruction or the hint device of indication or element must have specific orientation, with
Specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " first ", " second "
It is only used for describing purpose, and it is not intended that indicate or hint relative importance.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", should be interpreted broadly " connection ", " being connected ", connect for example, it may be fixing, it is also possible to be to dismantle connection, or connect integratedly
Connect；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Language is at concrete meaning of the present utility model.Additionally, in description of the present utility model, except as otherwise noted, " multiple ", " some "
It is meant that two or more.
