Paper cutter

A paper cutter, comprising:

• a base having a stationary blade attached to a lateral thereof;
• a fixing seat fixed to the base adjacent to one end of the stationary blade and having a connecting portion extending upward from the base, wherein the connecting portion is atop, peripherally formed with a plurality of teeth, and is formed centrally with a through hole for allowing a shaft to pass therethrough;
• a connecting element having a rotatory portion that is formed with a slot for allowing the shaft to pass therethrough and being atop provided with a plurality of recesses for receiving teeth;
• and
• a movable blade having a lower edge formed as a curved edge and having a front end contacting a side of the rotatory portion and separated from the fixing seat by the rotatory portion,
• wherein a pressing plate and an elastic pressing plate are mounted successively around the shaft and separated from the connecting element by the movable blade while a fastener is coupled with the shaft to abut against the elastic pressing plate so as to normally force the movable blade to contact the stationary blade closely,
• whereby when the movable blade is pushed downward, the connecting element is driven to rotate and move along the teeth while approaching and sliding with respect to the stationary blade.
