Background

In general, in order to improve the cutting effect of scissors, except for using scissors, the cloth is cut by rolling a circular hob on the cloth to cut the cloth, instead of using scissors, so as to obtain a relatively level cut edge, as disclosed in taiwan patent M393524, "rotary cutter".

However, in the above-mentioned wheel knife, in terms of the structural design, in order to obtain a desired cutting performance for the cloth, the blade is very sharp, and careless handling may cause an accident of cutting accidentally, and particularly, in the case of storage without use, care is required to be taken to prevent the occurrence of an unnecessary accident.

To solve the safety concerns, manufacturers add a circular guard plate or sheath (taiwan patent M378236 "soft cloth cutter sheath") under the blade, and make the guard plate have a proper pushing function, so that when the wheel cutter is not used, the guard plate can be pushed to cover the whole blade, thereby effectively avoiding the accident of accidentally injuring people, and when the wheel cutter is used, the guard plate is slightly pushed to deviate, so that the blade can be partially exposed, thereby performing the normal cutting function.

However, the guard plate of the aforementioned wheel knife can only be moved in two stages in design, i.e. the blade forms two functional configurations of covering protection and partially exposing the blade, under such a functional configuration, the blade has only a single knife-out angle and the blade body is entirely smooth surface, which will limit the smoothness of the cutting operation virtually, and the whole manufacturing cost is increased no matter what is called the "circular guard plate" or "sheath".
