[0002] An existing patent (publication number: CN213320265U) proposes a paper cutting device for accounting. It includes a loading plate with a pressure plate positioned above it. The pressure plate has a first rectangular hole at its top, a movable block positioned within the first rectangular hole, a second rectangular hole positioned within the top of the movable block, and a movable column positioned within the second rectangular hole. A cutting blade is fixedly connected to the bottom of the movable column. The top of the movable column is fixedly connected to a movable plate positioned above the movable block. The movable plate and the movable block are connected via an elastic component. The top of the movable plate is fixedly connected to a fixed block, and a pull ring is fixedly connected to the top of the fixed block. However, this device, which "has a pull ring fixedly connected to the top of the fixed block," relies on a cutting blade within the top plate to cut the paper within the loading plate. The operator manually presses the pull ring on the cutting blade to move the cutting blade. Uneven pressure can result in some paper being left uncut, impacting the device's yield rate.
