In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width "," thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer ", " up timeThe orientation or position relationship of the instruction such as pin ", " counterclockwise ", " axial direction ", " radial direction ", " circumference " be based on orientation shown in the drawings orPosition relationship, it is for only for ease of and describes the present invention and simplify description, rather than indicates or imply that signified device or element mustThere must be specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importanceOr the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed orImplicitly include at least one this feature.In the description of the invention, " multiple " are meant that at least two, such as two, threeIt is individual etc., unless otherwise specifically defined.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " fixation " etc.Term should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally；Can be that machinery connectsConnect or electrically connect；Can be joined directly together, can also be indirectly connected by intermediary, can be in two elementsThe connection in portion or the interaction relationship of two elements, limited unless otherwise clear and definite.For one of ordinary skill in the artFor, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.
In the present invention, unless otherwise clearly defined and limited, fisrt feature can be with "above" or "below" second featureIt is that the first and second features directly contact, or the first and second features pass through intermediary mediate contact.Moreover, fisrt feature existsSecond feature " on ", " top " and " above " but fisrt feature are directly over second feature or oblique upper, or be merely representative ofFisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " lower section " and " below " can beOne feature is immediately below second feature or obliquely downward, or is merely representative of fisrt feature level height and is less than second feature.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically showThe description of example " or " some examples " etc. means specific features, structure, material or the spy for combining the embodiment or example descriptionPoint is contained at least one embodiment or example of the present invention.In this manual, to the schematic representation of above-mentioned term notIdentical embodiment or example must be directed to.Moreover, specific features, structure, material or the feature of description can be with officeCombined in an appropriate manner in one or more embodiments or example.In addition, in the case of not conflicting, the skill of this areaArt personnel can be tied the different embodiments or example and the feature of different embodiments or example described in this specificationClose and combine.
Although embodiments of the invention have been shown and described above, it is to be understood that above-described embodiment is exampleProperty, it is impossible to limitation of the present invention is interpreted as, one of ordinary skill in the art within the scope of the invention can be to above-mentionedEmbodiment is changed, changed, replacing and modification.
