Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0021] For ease of description, spatially relative terms, such as "upper", "lower", "left", "right", and the like, can be used herein for describing an element's or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
