Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0044] The foregoing description, for purposes of explanation, sets forth specific values and arrangements of components and steps that are subject to many variations in the light of specific circumstances and / or material or workpiece shapes. Such examples, while indicating preferred embodiments, are not intended to limit or restrict the various concepts taught herein. It will be appreciated that the dimensions of the parts shown in the drawings are not necessarily to scale, and have been shown as such for illustrative purposes only. Techniques, methods, and apparatus known to those of ordinary skill in the art can not be discussed in detail, but are contemplated as being part of the specification, where appropriate. In all examples shown and discussed herein, any specific values are to be interpreted as merely illustrative of the examples, and not as a limitation thereon. Thus, other examples of the exemplary embodiments can have different values. It is noted that like numbers and letters on the figures identify like parts throughout the disclosure, and thus, once an item is defined in one figure, it is not necessary to discuss it further in connection with other figures where it is shown and / or discussed.

[0045] In the description of the present application, it is necessary to understand that the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship is usually based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, without making the opposite statement, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, therefore, it cannot be understood as a limitation on the scope of protection of the present application; The orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0046] For the convenience of description, spatial relative terms such as "above", "upper", "on", "top", "bottom", etc. can be used herein to describe the spatial relationship of one device or feature to other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawing is inverted, the device described as "above" or "on" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0047] In addition, it should be noted that the use of the words "first", "second" and the like to describe various components is merely intended to facilitate the differentiation of the corresponding components, and the above words have no special meaning unless otherwise stated, therefore, it cannot be understood as a limitation on the scope of protection of the present application.

[0048] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
