The closed storage assembly 3 can store documents and has a seal to avoid problems such as document dropping or damage, and has good wear resistance and stain resistance on the outside. The space adjustment and disassembly assembly 4 can be quickly disassembled to clean the inside of the briefcase, which helps to keep the bag hygienic and avoid the breeding of bacteria and viruses.

[0024] Please refer to Figure 2 , in this embodiment, the wear-resistant chassis assembly 2 includes a waterproof protective sleeve 201, a wear-resistant support block 202, a shaping plate 203, a sealing strip plate 204, and a first magnetic attraction block 205; the lower end of the waterproof protective sleeve 201 is fixedly installed with a wear-resistant support block 202, and a shaping plate 203 is placed in the waterproof protective sleeve 201 in a limited manner; the side end of the waterproof protective sleeve 201 is snap-fitted with a sealing strip plate 204; a first magnetic attraction block 205 is arranged at the side end of the sealing strip plate 204. Open the first magnetic attraction block 205 at the side end of the sealing strip plate 204 and take out the shaping plate 203 from the waterproof protective sleeve 201 for later cleaning. At the same time, the wear-resistant support block 202 at the lower end of the waterproof protective sleeve 201 has a wear-resistant protection function, preventing excessive friction at the bottom of the briefcase and reducing the service life of the briefcase.

[0025] Please refer to Figures 3 - 4, in this embodiment, the closed storage component 3 includes a load-bearing bottom bag 301, a non-woven fabric bag 302, a sealed package bag 303, a back strap 304, an iron block 305, a second magnetic attraction block 306, and a limit clamping block 307; the upper end of the waterproof protective cover 201 is fixedly connected to the load-bearing bottom bag 301; the upper end of the load-bearing bottom bag 301 is fixedly connected to the non-woven fabric bag 302, and the upper end of the non-woven fabric bag 302 is fixedly connected to the sealed package bag 303; the side end of the non-woven fabric bag 302 is connected to the back strap 304; the side end of the non-woven fabric bag 302 is fixedly provided with the iron block 305; the side end of the sealed package bag 303 is fixedly connected to the second magnetic attraction block 306; the upper end of the load-bearing bottom bag 301 is fixedly installed with the limit clamping block 307. The non-woven fabric bag 302 at the upper end of the load-bearing bottom bag 301 has good wear resistance and stain resistance. Limiting and clamping the second magnetic attraction block 306 at the side end of the sealed package bag 303 into the iron block 305 at the side end of the non-woven fabric bag 302 can provide sealed protection for the documents to avoid the loss or damage of the documents.
