Detailed Description
The utility model is further described below with reference to the drawings and the detailed description. Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in numerous different ways without departing from the spirit or scope of the embodiments of the present utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
In the following embodiments, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally formed; the device can be mechanically connected, electrically connected and communicated; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the embodiments of the present application will be understood by those of ordinary skill in the art according to the specific circumstances.
For better description, the left direction is the back and the right direction is the front of fig. 1. It is to be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counter-clockwise," "axial," "radial," "circumferential," "end," "side," and the like are directional or positional relationships as indicated based on the drawings, merely to facilitate describing and simplifying the description of the embodiments of the present utility model, and do not indicate or imply that the devices or elements being referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the embodiments of the present utility model.
