Abstract: The present invention relates to providing active protection through a safe structure of a paper shredder. It comprises a paper shredder upper cover and a paper shredder plate disposed on the paper shredder upper cover. Different from prior art paper shredders, which are provided with independent safe switches, the paper shredder plate of the present invention, is configured with a touch structure and a safe power supply switch. When closed, the paper shredder plate prevents users from accidentally touching the shredding blade, and the like. Inside the paper shredder, it starts the paper shredder and guarantees the paper shredder's normal operation on the one hand, and prevents forced feeding of non-expected items on the other hand. In the later case, the structure disposed on the inner surface of the paper shredder plate provides dual protection and is capable of stopping the paper shredding from working, whereby the safety of users is enhanced.
