The clamping assembly is arranged at the central position of the folding pages. The clamping assembly includes a bottom plate and two side plates. The side plates are arranged on the left and right sides of the bottom plate. Stamped, curled, and flanged edges are provided at the bottoms of the two side plates and the left and right sides of the bottom plate. The bottoms of the side plates and the left and right sides of the bottom plate are matched through the stamped, curled, and flanged edges, and a pin shaft is provided at the connection between the two for fixation. The two side plates can be flipped through the pin shaft. Inner flanges that are folded inward are provided on the upper, lower, left, and right sides of the side plates. The inner flanges at the bottoms of the side plates are arranged at intervals with the stamped, curled, and flanged edges at the bottoms. Two fixing frames are arranged between the two side plates. Each fixing frame includes a connecting plate and two syringe barrels. The two syringe barrels are arranged on the inner side surface of the connecting plate. The syringe barrels on one of the connecting plates are hollow shafts. The two fixing frames are connected to each other in a clamped manner by inserting the two syringe barrels into the other two syringe barrels. The fixing clip is clamped in multiple inner flanges of the side plates through the connecting plate.

[0006] Preferably, outer flanges that are folded outward are provided on the upper, lower, left, and right sides of the connecting plate in the fixing frame.

[0007] Preferably, the width of the outer flange is smaller than the width of the inner flange.

[0008] Preferably, the end portions near the inner sides of the inner flanges at the tops of the side plates are folded downward, and the end portions near the inner sides of the inner flanges at the bottoms of the side plates are folded upward.

[0009] The beneficial effects of the present utility model are as follows: By providing outward flanges on the upper, lower, left, and right sides of the side plate, in cooperation with inward flanges provided on the upper, lower, left, and right sides of the side plate, the fixing frame is snapped onto the inward flange of the side plate through the outward flange provided on the connecting plate, achieving the fixation of the fixing frame. Moreover, the end of the inward flange at the top of the side plate close to the inner side is folded downward, and after the connecting plate is snapped into the side plate, it can fix the connecting plate through its own elasticity, preventing the fixing frame from falling off the side plate when clamping documents; and both the inward flanges and outward flanges on the side plate and the connecting plate are directly formed by stamping, eliminating the need for installing springs during the installation process, which can further improve the production efficiency of the folder.

[0015] The technical solutions of the present utility model will be further specifically described below through embodiments in conjunction with the drawings.

[0016] Embodiment: A new type of folder that can be folded bidirectionally, as Figures 1 - 4As shown in the figure, it includes a folding page 10 and a clamping assembly 11. The clamping assembly 11 is arranged at the central position of the folding page 10. The clamping assembly 11 includes a bottom plate 1 and two side plates 2. The side plates 2 are arranged on the left and right sides of the bottom plate 1. Stamping and curling flanges 3 are provided at the bottoms of the two side plates 2 and the left and right sides of the bottom plate 1. The bottoms of the side plates 2 and the left and right sides of the bottom plate 1 are matched through the stamping and curling flanges 3, and a pin shaft 9 is provided at the connection between the two for fixation. The two side plates 2 can be flipped through the pin shaft 9. Inner flanges 4 that are folded inward are provided on the upper, lower, left, and right sides of the side plates 2. The inner flanges 4 at the bottom of the side plates 2 are arranged at intervals with the stamping and curling flanges 3 at the bottom. Two fixing frames 5 are provided between the two side plates 2. Each fixing frame 5 includes a connecting plate 6 and two syringe barrels 7. The two syringe barrels 7 are both arranged on the inner side surface of the connecting plate 6. The syringe barrel 7 on one of the connecting plates 6 is a hollow shaft. The two fixing frames 5 are connected to each other by inserting the two syringe barrels 7 into the other two syringe barrels 7. The fixing clip is clamped in the multiple inner flanges 4 of the side plates 2 through the connecting plate 6.

[0017] Outward flanges 8 that are folded outward are provided on the upper, lower, left, and right sides of the connecting plate 6 in the fixing frame 5; the width of the outward flanges 8 is smaller than the width of the inner flanges 4; the end near the inner side on the inner flange 4 at the top of the side plate 2 is folded downward, and the end near the inner side on the inner flange 4 at the bottom of the side plate 2 is folded upward.

[0018] Principle of the present utility model: When in use, first insert the two fixing frames 5 into the document, and the two fixing frames 5 are connected to each other by inserting the two syringe barrels 7 into the other two syringe barrels 7. The combined fixing frames 5 are installed on the two side plates 2, and the connecting plate 6 is fixed through the inner flanges 4 on the side plates 2. When the document needs to be flipped through, only need to take out one of the fixing frames 5 from the side plate 2 on the same side, then the fixing frame 5 can rotate around the pin shaft 9 on the same side. During the installation process, the inner flanges 4 and the outward flanges 8 on the side plates 2 and the connecting plate 6 are directly formed by stamping. The installation of springs can be omitted during the installation process, which can further improve the production efficiency of the folder.
