The cover 600 can be installed and removed through a simple dismounting operation, facilitating the user to flexibly switch between different use scenarios.

[0052] For example, the cover 600 can adopt a buckle type design; or the cover 600 can also be fixed by thread connection or magnetic attraction or other ways to meet the needs of different users.
