[0049] In the description of the embodiments of the present invention, unless otherwise clearly defined and limited, the terms "mounted", "connected", and "coupled" shall be construed broadly. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0050] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, it cannot be understood as a limitation of the present invention. In addition, terms such as "first", "second", and other numerical terms used herein do not imply an order or sequence unless explicitly indicated herein.

In addition to the orientation depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is turned over, an element described as "below" or "beneath" another element or feature will be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein are to be interpreted accordingly.
[0052] In the above discussion, unless otherwise specified, when used to describe a numerical value, the terms "about", "approximately", "substantially", etc. mean a variation of + / −10% of that value.
