Abstract
A one-way driving mechanism for the paper removal device of a shredder is disclosed. A transmission gear set is disposed between the cutting blades and paper-feeding wheels of the shredder. The primary gear of the transmission gear set is mounted on the rotary shaft of the cutting blades. The primary gear has at least one interference element. When the rotary shaft rotates in the shredding direction, the interference element connects and rotates with the end part of the rotary shaft. When the rotary shaft rotates in the reverse direction, the interference element is separate from the end part of the rotary shaft. This ensures that the paper-feeding wheels remain static in the REV mode.
