[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0017] The terms "including" and "having" and any variations thereof in the description, claims, and drawings of the present application are intended to cover without excluding other content. The word "a" or "an" does not exclude the existence of multiple. Unless otherwise stated, "multiple" means two or more (including two). Similarly, "multiple groups" means two or more groups (including two groups).

[0018] The orientation terms appearing in the following description are all the directions shown in the drawings and do not limit the specific structure of the present application. For example, in the description of the present application, terms such as "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present application.

[0019] In addition, expressions indicating directions for explaining the operations and structures of the components in this embodiment, such as the X direction, Y direction, and Z direction, are not absolute but relative. Although these indications are appropriate when the components are in the positions shown in the figures, when these positions change, these directions should have different interpretations to correspond to the changes.
