The component of the embodiment of the utility model described and shown in the drawing here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiment of the utility model provided in the drawing is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the scope of the utility model protection.

[0019] It should be noted that like reference numerals and letters refer to like items throughout the several views, and once an item is defined in one view, it should not be further defined and explained in subsequent views.

[0020] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed during use, which is merely for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0021] The terms "first", "second", "third" and the like are merely used for differentiation in description and cannot be understood as indicating or implying relative importance.

[0022] The terms "parallel", "vertical" and the like do not mean that the components must be absolutely parallel or vertical, but can be slightly inclined. For example, "parallel" merely means that its direction is relatively more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly inclined.

[0023] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal, vertical or overhanging, but can be slightly inclined. For example, "horizontal" merely means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0024] In addition, the terms "approximately", "substantially" and the like are intended to indicate that the relevant content is not required to be absolutely accurate, but can have some deviation. For example, "approximately equal" does not mean only absolute equality, as it is difficult to achieve absolute "equality" in actual production and operation processes, and there is generally some deviation. Therefore, in addition to absolute equality, "approximately equal" also includes the above-mentioned case of having some deviation. Taking this as an example, in other cases, unless otherwise specified, the terms "approximately", "substantially" and the like have similar meanings as above.

[0025] In the description of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "provision", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication between two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
