ABSTRACT:
This invention reveals a crank roller paper cutting device, which comprises a base, a supporter, a handle part, a master roller, a slave roller, and a group of speed-reducing gears. Via the group of speed-reducing gears, handle part correlates to the master roller and slave roller at one terminal, both of the master roller and slave roller are captured by the open bores therewith on the supporter. While the other ends of master roller and slave roller are suspended in the air, where a removable positioning block is attached. Upon the above said positioning block, there are two open bores or blink holes in correspondence to the master roller and slave roller respectively. Around the master roller and slave roller are many removable regulating cylinders or one regulating cylinder in different thickness. This crank roller paper cutting device is reasonable in design, easy to use and safe in operation for a wide range of applications, particularly valuable for kindergarten enlightenment education.
