Description

cutting machine

The present invention relates to a cutting machine for cutting paper.

From the prior art, a so-called press-cut type cutting machine has been known. By rotating the upper blade (cutting blade) with respect to the base body, the paper placed on the base body can be separated from the upper blade by the upper blade (cutting blade). Cuts are made by the coordinated action of the lower blades.

In the prior art, the upper blade and the lower blade in a press-cut type cutting machine are crimped by a crimping mechanism capable of restricting the relative rotational movement of the two. Basically, the cutting machine uses the action of the crimping mechanism so that the upper blade and the lower blade will not rotate relative to each other unless the user directly rotates the upper blade.

On the other hand, the movement of the upper blade usually depends only on the press-contact mechanism. Therefore, for example, when the surrounding objects collide with the upper blade and give an unexpected operating force to the upper blade, for example , or when the upper blade is excessively worn, or when the above-mentioned crimping mechanism is damaged or loosened, it can be presumed that there will be upper and lower blades regardless of the user's restraint. Relative rotation occurs.
