Background
A stapler is a stationery that binds document sheets and is now widely used in offices.
The existing stapler generally comprises a machine face, a staple pressing sheet, a machine core, a staple pusher, a curved needle table, a machine bottom and other parts. When the stapler is used, pressure is applied to the machine face, the pressure is transmitted to the staple pressing sheet through the machine face, and then the staple pressing sheet pushes the staple, so that the staple breaks through paper, and the legs of the staple are bent under the action of the bead position plate, so that the function of stapling the paper by the stapler is realized.
The existing staples can leave bulges on both sides of paper after binding, and when a plurality of bound files are stacked together, the positions with the staples can be higher than other positions, and are difficult to store. This is particularly true when the number of individual documents is small. In order to solve the defect, a stapler without staples is arranged, and the paper produced by punching holes is fixed by inserting the punched paper into the holes, so that the purpose of flattening the paper surface and facilitating storage is realized. However, such a staplers have many disadvantages, firstly, the number of staplers is very limited, usually only less than ten documents can be stapled, secondly, the stapling is not firm and easy to spread, and finally, the damage to paper surface is serious, so that the strength of the paper is greatly reduced, the paper is easy to break at the stapling position, and therefore, the stapler can only be applied to thicker paper such as A4 paper and the like, and is not suitable for thinner paper such as notes and the like.

Finally, the pressing block 8 is loosened, and the devices are reset under the action of the first spring 17. In the process of taking down the paper 7, the bound lower nail body is separated from other lower nail bodies due to the limiting function of the lower nail storage groove 23, and the boss 5 is prevented from falling off the nail barrel 2 in a mode of interference fit and friction surface.
As shown in fig. 5, in the first binding mode, the upper and lower covers 1 and 4 are higher than the paper surface, so that the number of sheets 7 is not very large, and stacking is not required after binding.
As shown in fig. 6, in the second binding mode, the upper and lower covers 1 and 4 are lower than the paper surface, so that the binding mode is suitable for the situation that the number of sheets 7 is large and the sheets 7 need to be stacked after binding, because of the flexibility of the sheets 7, the pressing force on the hands is only required to be increased during binding, and the depth of inserting the boss 5 into the nail barrel 2 is higher.
After binding, because the knife edge 3 is outwards spread in the process of interference fit generation, the paper 7 at the periphery side is extruded, and pressure exists between the paper 7 and the nail barrel 2, so that the binding stability can be improved. Meanwhile, the puncture needle 6 is inserted into the scraps, so that the scraps can be fixed together, and the scraps are prevented from extruding the upper nail cover 1 to cause the falling of the staples.
