This application discloses a waste collection device for a paper cutter, belonging to the field of waste collection technology for paper cutters. It includes a housing. The design is novel and the device ingenious. A second electric telescopic rod extends to move a first push block upwards. As the first push block gradually moves out of the slot, two second push blocks return to their original position with the spring, causing two movable plates to move away from the springs. When the movable plates move, they drive the second push blocks away from the first push blocks via a fixed rod. At this point, the second push blocks push the waste material into the collection trough on the cutting table. This reduces the risk of being cut by the cutting blade during manual operation. The splash guard prevents the waste material from scattering when the second push blocks push it, thus improving the waste collection efficiency and greatly enhancing the practicality of the device.
