Specific embodiment
It is practical to this below in conjunction with attached drawing for the above objects, features, and advantages of the utility model can be clearer and more comprehensible
Novel specific embodiment elaborates.
The embodiments of the present invention are described with detailed reference to attached drawing now.Now with detailed reference to the excellent of the utility model
Embodiment is selected, its example is shown in the drawings.In the case of any possible, will be come in all the appended drawings using identical label
Indicate the same or similar part.
In addition, although term used in the utility model is selected from public term, this reality
Some terms mentioned in novel specification may be applicant by his or her judgement come selection, and detailed meanings exist
Illustrate in the relevant portion of description herein.
Furthermore, it is desirable that not only by used actual terms, and be also to the meaning contained by each term
To understand the utility model.
