[0025] As an embodiment, to facilitate installation and replacement, clamping seat 3 and clamping part 210 can be detachably connected, and the existing paper clip can also be directly modified.Specifically, clamping seat 3 and clamping part 210 are clamped together, and the structure is simple and convenient to install.Further, the position corresponding to clamping surface 310 on the rear side of clamping seat 3 is provided with a clamping groove 320, clamping part 210 is clamped in clamping groove 320 to realize the connection of clamping seat 3 and clamping part 210, clamping seat 3 is installed from front to back on clamping part 210, at this time, clamping seat 3 is slidingly fitted on clamping plate 1, clamping seat 3 does not need to be suspended, and installation is more convenient.Specifically, clamping surface 310 is arranged on the bottom surface of clamping seat 3 corresponding to the position of clamping groove 320, that is, the position of clamping surface 310 corresponds to clamping part 210, the pressing force of clamping surface 310 is maximum, the pressing effect is good, and the reliability is high.

[0026] As an embodiment, the upper surface of clamping seat 3 is provided with an opening 330 communicating with clamping groove 320, to facilitate observation whether clamping part 210 is installed in place.Specifically, since the middle of the front end of clamping part 210 has a metal strip protruding upward, a positioning protrusion 321 is arranged on the surface of clamping groove 320 close to clamping plate 1, the two ends of the metal strip are clamped in clamping groove 320, and the middle part of the metal strip abuts against the positioning protrusion 321 to realize the installation of clamping part 210 and clamping seat 3, and the connection is firm and reliable.

[0027] As an embodiment, the rear end of clamping groove 320 penetrates through clamping seat 3 downward, clamping part 310 is clamped in the front end of clamping groove 320, clamping part 310 moves from the rear end of clamping groove 320 to the front end of clamping groove 320, and the inner side wall of the rear end of clamping groove 320 plays a guiding role on clamping part 310, to facilitate accurate clamping of clamping part 310 in the front end of clamping groove 320.

[0028] As an embodiment, in order to better clamp the paper or file, a plurality of friction protrusions 311 are arranged on the clamping surface 310 to increase the friction between the paper and the clamping surface 310. Specifically, the friction protrusions 311 are long strip-shaped protrusions arranged along the width direction of the clamping portion 310, have a large contact area, and have a large friction.

[0029] As an embodiment, a pushing protrusion 340 protruding from the surface of the clamping seat 3 is arranged at the front end of the clamping seat 3, so that the clamping seat 3 can be easily pushed upward, and the paper or file can be easily placed above the corresponding clamping portion 2 of the clamping plate 1.

[0030] Figure 3 is a perspective view of the paper clip body of the paper clip, as Figure 3 shown in the embodiment, the paper clip body 2 includes a clamping portion 210 and a hinged seat 220, the hinged seat 220 is used to be fixed on the clamping plate 1, the rear end of the clamping portion 210 is hinged on the hinged seat 220, and the front end of the clamping portion 220 is used to be pressed on the clamping plate 1. First, lift the clamping portion 220, place the paper or file on the clamping plate 1, the paper or file is located between the clamping portion 220 and the clamping plate 1, release the hand, and use the torsional spring between the clamping portion 220 and the hinged seat 220 to make the clamping portion 220 reset downward and press on the paper or file. The torsional spring is located on the hinge shaft in the hinged seat 220, and the clamping portion 220 is hinged with the hinged seat 220 through the hinge shaft.

[0031] Figure 4 is a perspective view of the paper clip applied to the file box, Figure 5 is a perspective view of the file box without the clamping seat, as Figure 4 and 5 shown in the embodiment, the utility model provides a file box, including clamping plate 1, paper clip body 2 and clamping seat 3, the hinged seat 220 of paper clip body 2 is fixed on clamping plate 1 through bolt, clamping seat 3 is installed on the clamping portion 210 of paper clip body 2. In the free state, the clamping seat 3 is pressed on the clamping plate 1 by the torsional spring between the hinged seat 220 and the clamping portion 210. When using, the paper or file can be placed between the clamping plate 1 and the clamping seat 3. Because when placing the paper or file, the middle part of the paper or file will be placed on the hinged seat 220, so that the two ends of the paper or file will be raised upward, which is not convenient for writing. Therefore, the bottom surface of the two ends of the clamping seat 3 is provided with a pressing protrusion 350, to prevent the two ends of the paper or file from being raised upward, which affects the use. The pressing protrusion 350 is used to abut against the upper surface of the two ends of the paper or file to realize the positioning of the paper or file.

[0032] The utility model discloses a principle is provided with the clamping seat 3 of clamping surface 310, install clamping seat 3 on clamping part 210, and clamping seat 3 and clamping part 210 synchronous motion, let clamping surface 310 press tightly file or paper on clamping plate 1, surface contact replaces line contact, and the contact area is big, can effectively press tightly to paper, and the reliability is high.

[0033] Action process: one, with finger to lift up and stir the convex 340, clamping seat 3 drives clamping part 210 to rotate upwards, let clamping seat 3 separate from clamping plate 1, the torsional spring is compressed at this time;Two, place paper or file on clamping plate 1;Three, release hand, and the torsional spring drives clamping seat 3 to reset downwards, and the clamping surface 310 of clamping seat 3 is pressed tightly on paper or file, at this time, press the convex 350 and rest on the upper surface of paper or file both ends and prevent paper from rising.

[0034] On the basis of the above scheme, if the various modifications or deformation of the utility model do not deviate from the spirit and scope of the utility model, if these modifications and deformation belong to the right claim and the equivalent technical scope of the utility model, then the utility model also intends to include these modifications and deformation.
