Please refer to Fig. 1, Fig. 2 and Fig. 3 together. A file folder 100 provided by the embodiment of the present invention is used to accommodate a stack of papers 300, including: a side bar 1 and a push buckle 2; the side bar 1 has Elastic stretching margin, the side bar 1 is provided with a first opening 11 on its side along its own length direction, and a paper stack 300 is placed in the first opening 11; the push buckle 2 includes a first card with an elastic stretching margin. Buckle 21, and the second buckle 22, the first buckle 21 is provided with a second opening 211, the side bar 1 is placed in the second opening 211, and the second buckle 22 is provided with a direction consistent with the second opening 211 The third opening 221, the first buckle 21 is accommodated in the third opening 221, and the second buckle 22 is slidably connected with the first buckle 21; wherein, the opening width of the third opening 221 is smaller than that of the second opening 211 Opening width, the second buckle 22 can slide from the side of the first buckle 21 away from the second opening 211 to the side of the first buckle 21 with the second opening 211, so as to narrow the second opening 211 and clamp the paper Stack 300.

The paper bundle 300 may be formed by stacking a plurality of sheets of paper, or may be formed by stacking a plurality of documents.

The side bar 1 should be made of elastic material, which has a certain elastic stretch margin, that is, it can be deformed when it is squeezed by external force, and return to its original shape when it is not squeezed by external force. The side bar 1 should be long enough, and its length should be greater than the side length of the sides required to clamp the bundle of paper 300 , so as to protect the side of the bundle of paper 300 . Specifically, it should be designed as a first opening 11 with a larger opening width, and a thicker paper bundle 300 can be placed in the first opening 11, and under the action of the clamping force of the first buckle 21, The first opening 11 can be closed to clamp the paper bundle 300 . The side bar 1 can be pre-set with various models, such as large, medium, small, etc., for example, the large side bar 1 has a first opening 11 with a larger opening width, which is suitable for clamping thicker The paper stack 300 of the medium-sized side bar 1 has the first opening 11 with a general opening width, which is suitable for clamping the paper stack 300 of medium thickness, and the small-sized side bar 1 has a small opening width.
