DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "lateral", "vertical", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and does not indicate or imply that the device or component referred to must have a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0021] It should be particularly noted that the "horizontal" and "vertical" in the present invention are used to illustrate the approximate positional relationship, rather than the strict "horizontal plane" or "vertical plane".
