DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0040] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours.
