    摘要： A rotary cutter knife provided with a guard member, which extends beyond the outer edge (21) of the rotary blade (20) to enhance the safety. The guard member is divided into two sub-members (30a, 30b), which can independently move between an extended position where an outer profile (31a, 31b) of the sub-member extends beyond an outer edge (21) of the rotary blade (20) and a retracted position where the outer profile (31a, 31b) of the sub-member is retracted such that the outer edge (21) of the rotary blade (20) is exposed. Thus, the cutting edge (21) of the rotary blade (20) is not exposed in the area where the cutting operation is not performed, and the cutting edge (21) is exposed only in a limited area associated with the cutting operation, such that the highly enhanced safety is realized.

    摘要： The present invention provides a cutter knife 10, which even if made with only the metal parts, smoothness of sliding operation of the blade is not degraded in time, even without lubricating oil nor friction resistant coating. A slider 30 of the cutter knife carries a rolling member 50, which is made rolling contact with the outer surface of the cutter knife. Further, the slider has a protrusion 35 which extends into the cutter knife body 11 and is engaged into a hole 25 formed on the blade 20. Since an external force applied onto the slider is received by the rolling member, the slider can be operated smoothly. Besides, the height of the protrusion is determined, such that the protrusion does not touch the inner surface of the cutter knife. Thus, the protrusion tip never interfere with the inner surface of the cutter knife, thereby the sliding operation of the slider would not be prevented.

    摘要翻译： 本发明提供一种切割刀10，即使仅用金属部件制造，即使没有润滑油也没有耐摩擦涂层，叶片的滑动操作的平滑性不会在时间上劣化。 切刀的滑块30承载与切刀的外表面滚动接触的滚动部件50。 此外，滑块具有延伸到切割刀主体11中并且与形成在刀片20上的孔25接合的突起部35.由于施加到滑动件上的外力被滚动部件容纳，所以滑块能够平稳地操作 。 此外，确定突起的高度，使得突起不接触切割刀的内表面。 因此，突起尖端不会干涉切割刀的内表面，因此滑块的滑动操作将不会被阻止。
