Attached drawing described herein is used for providing a further understanding of the present invention, forms the part of the present invention, this hair
Bright exemplary embodiment and its explanation do not constitute improper limitations of the present invention for explaining the present invention.In the accompanying drawings：
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Some vocabulary has such as been used to censure specific components among specification and claim.Those skilled in the art should
It is understood that hardware manufacturer may call same component with different nouns.This specification and claims are not with name
The difference of title is used as the mode for distinguishing component, but is used as the criterion of differentiation with the difference of component functionally.Such as logical
The "comprising" of piece specification and claim mentioned in is an open language, therefore should be construed to " include but do not limit
In "." substantially " refer in acceptable error range, those skilled in the art can be described within a certain error range solution
Technical problem basically reaches the technique effect.
In the description of the present invention, it is to be understood that term " on ", " under ", "front", "rear", "left", "right", level "
