Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the present invention is described further, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
It should be noted that when component is referred to as " being fixed on " another component, it can be directly on another component
Or there may also be components placed in the middle.When a component is considered as " connection " another component, it can be directly connected to
To another component or it may be simultaneously present component placed in the middle.When a component is considered as " being set to " another component, it
Can be set up directly on another component or may be simultaneously present component placed in the middle.Term as used herein is " vertical
", " horizontal ", "left", "right" and similar statement for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article and belong to the technical field of the present invention
The normally understood meaning of technical staff is identical.Used term is intended merely to description tool in the description of the invention herein
