Of course, other detection mechanisms 700 may be used.

The above is only the part or the preferred embodiment of the present invention, no matter the characters or the drawings can not limit the protection scope of the present invention, all under the whole concept of the present invention, the equivalent structure transformation performed by the contents of the specification and the drawings is utilized, or the direct/indirect application in other related technical fields is included in the protection scope of the present invention.
