Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or may have an intervening element present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or may have an intervening element present. When an element is referred to as being "fixedly connected to" another element, it can be a common fixing connection method such as welding, bolting, or gluing.
