The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-4, the present invention provides an embodiment: a paper cutter comprises a bottom plate 1, wherein one side of the bottom plate 1 is in shaft pin connection with a first connecting rod 3, and the other side of the bottom plate 1 is in shaft pin connection with a second connecting rod 10; the other ends of the first connecting rod 3 and the second connecting rod 10 are in shaft pin connection with a paper cutter 6; because the first connecting rod 3 and the second connecting rod shaft 10 are in pin connection with the bottom plate 1, on one hand, the two connecting rods can rotate on the bottom plate 1, and on the other hand, the paper cutter 6 is fixed; meanwhile, the angle of the rotatably connected paper cutter 6 can be adjusted, so that a user can adjust the gap between the cutter edge of the paper cutter 6 and the bottom plate 1 according to the thickness of the paper to be cut;

in order to enable the paper cutter 6 to move up and down, shaft pin seats 2 are arranged in the middle of the paper cutter 6 and the middle of the bottom plate 1, and the shaft pin seats 2 are in shaft pin connection with a first pressure lever 12; the first pressing rod 12 is pulled to move up and down, so that the paper cutter 6 can conveniently move up and down, and meanwhile, the first pressing rod 12 is positioned in the middle of the paper cutter 6 and the bottom plate 1, so that the force is conveniently applied, and the problem that the paper can be completely cut by increasing the strength when the paper is cut to half in the process of cutting the paper by the conventional paper cutting equipment is solved.

The first pressure lever 12 is rotationally connected with the axle pin seat 2 on the paper cutter 6 through the linkage plate 7, is in axle pin connection with the first pressure lever 12 through one end of the linkage plate 7, and is rotationally connected with the axle pin seat 2 on the paper cutter 6 through the other end of the linkage plate 7, so that the up-and-down moving angle of the paper cutter 6 can be adjusted;

the linkage plate 7 can be structurally characterized in that two vertical plates are arranged at the upper end, a first pressure rod 12 is arranged between the two vertical plates, then a cylindrical shaft penetrates through the two vertical plates to enable the first pressure rod 12 to be rotatably installed on the linkage plate 7, meanwhile, the lower end of the linkage plate 7 is also plate-shaped and directly inserted into a shaft pin seat 2 on a paper cutter 6, and the cylindrical shaft penetrates through the shaft pin seat 2 on the paper cutter 6 to enable the paper cutter 6 to be rotatably connected with the linkage plate 7;

in order to keep the position of the paper cutter 6 unchanged after adjustment, one end of each of the first connecting rod 3 and the second connecting rod 10 is rotatably connected with the base plate 1, and a bolt 9 is screwed on the other end of each of the first connecting rod 3 and the second connecting rod 10, so that the rotated paper cutter 6 is positioned by tightening the bolt 9.

Because the first connecting rod 3 and the second connecting rod 10 are both provided with the scale values 5 for displaying angles, and the circular positions of the scale values 5 are also provided with the pointers 14, wherein the pointers 14 are concentrically arranged with the cylindrical shafts on the paper cutters 6, the set scale values 5 are matched with the pointers 14, so that a user can more intuitively know the angles adjusted by the paper cutters 6, and the pointers 14 are concentrically arranged with the cylindrical shafts arranged at the two ends of the paper cutters 6, so that the pointers 14 can synchronously rotate with the paper cutters 6, and the angles adjusted by the paper cutters 6 can be conveniently and accurately read. It should be noted that, the cylindrical shafts are respectively arranged at the two ends of the paper cutter 6, and the cylindrical shafts are inserted into the shaft pin holes formed in the first connecting rod 3 and the second connecting rod 10, so that the paper cutter 6 is fixed at one end of each of the two connecting rods, which is far away from the bottom plate 1.

In order to ensure that the paper cutting knife 6 cuts paper neatly, a second pressure lever 13 used for pressing paper on the bottom plate 1 is connected between the first connecting rod 3 and the second connecting rod 10 in a rotating mode, and the second pressure lever 13 is used for moving along with the first connecting rod 3 and the second connecting rod 10 synchronously, so that the paper cutting knife 6 moves downwards more and more tightly the paper is pressed, and the problem of uneven cut caused by paper conveying is effectively solved.

In order to avoid the problem that the second pressure lever 13 excessively presses paper to cause the phenomenon that the paper is folded due to excessive pressing, and the cut is uneven, the first connecting rod 3 and the second connecting rod 10 are also provided with the pressing device 11 for fixing the second pressure lever 13, and the distance between the second pressure lever 13 and the bottom plate 1 is limited by the arrangement of the pressing device 11, so that the second pressure lever 13 can not only press the paper, but also prevent the phenomenon that the paper is folded due to excessive pressing; the paper cuts can be made flat by the provision of the presser 11.

Because the presser 11, including picture peg 16, with the guide bar 18 that picture peg 16 is connected and with guide bar 18 sliding fit's guide sleeve 19, because utilize guide bar 18 to slide in guide sleeve 19, when second depression bar 13 and paper contact, second depression bar 13 promotes guide sleeve 19 and slides on guide bar 18, the buffering collides with the rigidity of paper, has effectively solved the paper and has appeared the problem of fold because of the rigidity collision leads to the paper.

Further, one end of the guide rod 18 is fixedly connected with the inserting plate 16 through a screw 17, and the other end of the guide rod 18 is provided with a piston 21; the arrangement of the piston 21 enables the guide sleeve 19 to slide more stably, and the guide sleeve 19 is fixedly connected with the second pressure lever 13, and the spring 20 is arranged in the guide sleeve 19, so that the second pressure lever 13 can be slowly and upwards lifted when being contacted with paper, even if the first pressure lever 12 is pressed by hands to exert force unevenly or pause, the guide sleeve 19 can be reset, the second pressure lever 13 is ensured to be contacted with the paper all the time, and the problem of contact interruption of the second pressure lever 13 and the paper cannot occur.

In order to facilitate the installation and fixation of the compactor 11, the first connecting rod 3 and the second connecting rod 10 are respectively provided with a jack 15, and the installation of the compactor 11 is realized by inserting the plugboard 16 into the jack 15 through the jacks 15 and the plugboard 16 which are in adaptive connection.

The base plate 1 is also provided with the backing plate 4, so that a paper cut can be positioned on the backing plate 4 and then matched with the paper cutter 6 to cut paper; because the handle 8 is further arranged at one end, far away from the bottom plate 1, of the first pressure lever 12, force application and grasping are facilitated, and meanwhile, the force for pressing the paper cutter 6 can be saved due to the arrangement of the handle 8.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
