The sizes of the cover and back cover of general folders are adapted to the size of A4 paper. It is not easy to unfold the test paper when placed in an ordinary folder, which is not conducive to students' correction of the test paper and subsequent use of the test paper. Therefore, application number: 201822168823.1 discloses an A3 test paper folder, including a cover, a back cover, and a spine. A clamp is provided at the side edge of the inner surface of the cover, and an elastic band is provided on the outer surface of the back cover. The two ends of the elastic band are connected to the cover by a fixing ring. The front cover and the back cover are fixedly connected, and the front cover and the back cover are buckled by stretching the elastic band toward the front cover. The lower edge of the inner surface of the back cover is provided with a supporting part, and the supporting part includes a supporting plate connected to the lower edge of the inner surface of the back cover and a baffle connected to the supporting plate. For the folder, the front cover and the back cover are opened, and the test paper can be squared on the front cover and the back cover. The clamp is provided at the side edge of the inner surface of the front cover, and one side of the test paper can be clamped and fixed.

A rectangular through-hole is provided, and the right end of the card rod 11 passes through the corresponding rectangular through-hole and extends to the right side of the limit ring 8 and is fixedly connected with a pull ring. A rectangular block 13 is fixedly connected to the top inner wall of the rectangular through-hole. A first groove 12 is provided on the top of the card rod 11, and a positioning rod 15 is fixedly connected between the inner walls on both sides of the first groove 12. The rectangular block 13 is slidably sleeved on the corresponding positioning rod 15, wherein a positioning hole is provided on the right side of the rectangular block 13 for slidingly sleeved with the corresponding positioning rod 15, and a spring 14 is fixedly connected between the right side of the rectangular block 13 and the right side inner wall of the corresponding first groove 12, and the spring 14 is movably sleeved on the corresponding positioning rod 15, and the positioning rod 15 has a lateral positioning effect on the corresponding card rod 11. The setting of the spring 14 can drive the card rod 11 to move and reset when it is in a stretched state and relaxes the tension; the utility model can separate and classify multiple test papers through a series of structural settings, and can adjust and sort the placed test papers, so as to facilitate subsequent search by personnel and improve the convenience of use.

[0026] Working principle: when in use, the subject label of the test paper stored in the test paper folder can be placed in the second label bag 16. When the test paper folder is opened to place the test paper, the test paper can be placed between the corresponding transparent bag 1 and the transparent plastic 2, and the type label of the test paper can be placed in the first label bag 3. In addition, by setting multiple classification components, multiple test papers can be separated and placed in the corresponding transparent bag 1. At the same time, with the set labels, it is convenient for personnel to find the test papers when they are used later. After the test papers are placed, the cover 100 of the test paper folder can be closed, and with the setting of the second folding strip 7 and the spine 101, it is convenient for personnel to perform the closing operation. After closing, the elastic band 103 can be pulled to clamp the elastic band 103 in the corresponding first card slot 102. The two elastic bands 103 and the multiple first card slots 102 can cooperate to achieve the fixing of the test paper folder cover 100 after closing. After closing and fixing, the setting of the blocking bar 6 can block the top of the test paper, reduce the situation that the test paper slides out when it is placed flat or upside down, and improve the placement stability.

[0027] When the test paper holder needs to be opened, the two elastic bands 103 can be pulled out of the corresponding first slots 102 to release the fixing of the test paper holder cover 100 and open the test paper holder;

[0028] After the test paper folder is opened and all the test papers are loaded, when the order of the test papers is adjusted according to personal needs, the two pull rings can be pulled to the right, and the pull rings drive the corresponding clamping rods 11 to move to the right, and the clamping rods 11 drive the corresponding positioning rods 15 to slide in the rectangular block 13, and the clamping rods 11 stretch the corresponding springs 14 to the right. When the clamping rods 11 are moved out of the corresponding second clamping grooves 10, the fixation of the limit ring 8 can be released. At this time, the limit ring 8 can be moved forward and removed from the corresponding T-shaped positioning shafts 9, and the fixation of the frontmost connecting strips 4 can be released. Multiple connecting strips 4 can be removed from the two T-shaped positioning shafts 9, and the corresponding connecting strips 4 can be sleeved on them from front to back in the order of installing the test papers. On the T-shaped positioning shaft 9, after the sleeve is completed, pull the pull ring again to make the spring 14 in a stretched state, and sleeve the limit ring 8 on the corresponding T-shaped positioning shaft 9 to cover the frontmost connecting strip 4. After the sleeve is installed, when the second card slot 10 is aligned with the corresponding card rod 11, relax the pulling force on the pull ring. At this time, the elastic force of the spring 14 in the stretched state drives the corresponding card rod 11 to move to the left into the second card slot 10, so that the limit ring 8 can be fixed. The detachable connecting strip 4 is convenient for personnel to sort the test papers according to their needs, thereby further facilitating personnel to search later and improving the convenience of use. After sorting, the test paper clamp can be closed and fixed in the same way as above.
