The outer surface of the box body is provided with a lockset and a handle, and a waterproof sealing ring is arranged at the opening and closing position of the upper cover of the box body and the box body.

As shown in fig. 2A-4, the multimedia pulverizing module 2 of the present invention is mainly used for pulverizing hard storage media, such as optical disks, usb disks, memory sticks, and storage chips contained in solid state disks. The multimedia crushing module 2 comprises a shell 21, a rotary cutter shaft group 22 arranged in the shell and a transmission gear group 23 arranged on a side plate at one end of the shell. The rotary knife shaft group 22 is composed of two rotary knife shafts 221 which are arranged side by side and opposite to each other, a plurality of saw-toothed blades 222 which are arranged at intervals are sleeved on each rotary knife shaft, and the blades 222 sleeved on the two rotary knife shafts which are arranged side by side and opposite to each other are arranged in a mutually staggered mode. Both ends of each rotary knife shaft 221 are fixed on the side walls of both ends of the housing 21, and the rotary knife shafts 221 are connected with the transmission gear set 23. An output shaft of the motor driving module 4 is connected with the transmission gear set 23, the transmission gear set 23 drives the two rotating cutter shafts 221 to rotate oppositely, the two rotating cutter shafts roll media, and the blades with sawteeth cut the crushed media.

For preventing the disintegrating slag after smashing from blockking up the blade, the utility model discloses be provided with the double-edged fine-toothed comb 223 between the blade 222 that the interval set up, the both ends cover of the double-edged fine-toothed comb 223 that the interval set up is established on connecting rod 224, and bolt fastening is passed through on the curb plate of casing 21 at connecting rod 224's both ends.

In addition, a material inlet 211 is formed on the surface of the housing 21 directly above the space between the two rotary knife shafts. When the optical disc, the memory bank, the shell-removed U disk and the memory chip of the solid state disk slide from the material inlet 211 and fall into a gap between the two rotating cutter shafts, the two rotating cutter shafts rotate oppositely to roll and press the medium and cut and crush the medium.

As shown in fig. 5A to 6, the paper media crushing module 3 of the present invention is mainly used for crushing paper media. It consists of a shell 31, a paper shredder core 32 and a transmission gear set 33 arranged on a side plate at one end of the shell. The paper shredder core 32 is composed of two rotating cutter shafts 321 which are arranged side by side and oppositely, each rotating cutter shaft is sleeved with a plurality of blades 322 which are arranged at intervals and provided with sawteeth, and the blades on the two rotating cutter shafts which are arranged side by side and oppositely are arranged in a mutually staggered way. The output shaft of the motor driving module 4 is connected with the transmission gear set 33 of the paper medium crushing module, and the paper crushing machine core 32 is driven to rotate through the transmission gear set 33. A feeding port 311 is formed on the surface of the housing 31 right above the space between the two rotary knife shafts. When the paper medium slides down from the feeding port 311 and falls into a gap between the two rotating cutter shafts, the two rotating cutter shafts are cut and crushed into paper scraps by the saw-toothed blades on the rotating cutter shafts.

For preventing the wastepaper after smashing from blockking up the blade, the utility model discloses be provided with grate 323 between the blade 322 that the interval set up, the both ends cover of the grate 323 that the interval set up is established on connecting rod 324, and the bolt fastening is passed through on the curb plate of casing 31 at the both ends of connecting rod 324.

Since the multimedia shredding module is mainly used for shredding hard storage media and the paper media shredding module is mainly used for shredding soft paper media, the thickness, the number of saw teeth and the sharpness of the saw teeth of the blade 222 on the multimedia shredding module and the blade 322 on the paper media shredding module are different. The blade 222 on the multimedia crushing module is made of high-strength high-wear-resistance alloy steel, the thickness of the blade is wide, the number of sawteeth on the blade is large, and the crushed storage medium particles are about 2-5mm. The blade 322 on the paper media shredding module is also made of high-strength high-wear-resistance alloy steel, compared with the blade 222 on the multimedia shredding module, the blade is narrow in thickness, the number of sawteeth on the blade is small, and shredded paper particles after being shredded are about 1-2mm.
