It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that when an element is referred to as "fixed on" or "set on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be a centering element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolting or gluing.
