Finally, it should also be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply these entities or that there is any such actual relationship or sequence between operations. Moreover, the terms "comprising", "comprising" or any other variation thereof are intended to encompass non-exclusive inclusion such that a process, method, article or terminal device that includes a list of elements includes not only those elements, but also a non-exclusive list of elements. other elements, or also include elements inherent to such a process, method, article or terminal equipment. Without further limitation, an element defined by the phrase "comprises a..." does not preclude the presence of additional identical elements in the process, method, article, or terminal device that includes the element.

A cutting device provided by the present disclosure has been introduced in detail above, and the principles and implementations of the present disclosure are described with specific examples herein. The core idea; meanwhile, for those skilled in the art, according to the idea of the present disclosure, there will be changes in the specific implementation and application scope. In conclusion, the content of this specification should not be construed as a limitation of the present disclosure.
