[0037] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment provides a paper fixing device, such as Figure 1-2 As shown, it includes a workbench 10, a paper pressing plate 20, a guide column 30 and a toggle mechanism 40. A groove 11 is provided on the workbench 10, and a slide key 12 is placed on the groove 11 and can move along the length direction of the groove 11. The paper pressing plate 20 is located above the slide key 12 and is connected to the workbench 10 with the slide key 12 through the guide column 30. The toggle mechanism 40 is disposed on the paper pressing plate 20, and is provided with an elastically connected plug block 42 and a sliding plate 43. The sliding plate 43 can drive the plug block 42 to move. After the paper is placed between the paper pressing plate 20 and the workbench 10, the plug block 42 is driven to abut against the outer wall of the guide column 30 to fix the height position of the paper pressing plate 20, thereby preventing the paper pressing plate 20 from moving, so that the paper is pressed and fixed on the workbench 10 by the paper pressing plate 20, and is ready for binding; or, the plug block 42 is driven away from the outer wall of the guide column 30 to release the paper pressing plate 20 and allow the paper pressing plate 20 to freely slide upward along the guide column 30, so that the paper is loosened by the paper pressing plate 20 and pulled out of the paper.

[0039] Specifically, the workbench 10 is a tabletop used in a conventional binding machine, on which a groove 11 is arranged along the length direction of the workbench 10. The sliding key 12 is constructed in the groove 11 and can slide along the length direction of the groove 11 to adjust its position.

[0040] like Figure 4 As shown, the guide post 30 is a straight rod structure, which passes through the paperboard 20 and the sliding key 12 in sequence and is fixedly installed on the workbench 10. The guide post 30 is vertically arranged at both ends of the paperboard 20, and its outer wall surface is constructed with a plurality of threaded circles arranged in the same direction. The threaded circles are all truncated cone-shaped structures inclined downward, and the inclination angle θ of the inclined surface is 30-75°. The upper end of the guide post 30 is a dome surface structure, and the lower end surface is a threaded step section, which passes through the sliding key 12, is fixed and embedded on the workbench 10.

[0041] like Figure 2 As shown, each guide post 30 is provided with a toggle mechanism 40, and the toggle mechanism 40 is arranged on the outside of the guide post 30. The toggle mechanism 40 includes a fixed plate 41, an insert block 42, a sliding plate 43 and a spring 44, wherein the fixed plate 41 is arranged horizontally and laterally, passes through the thickness of the vertically arranged sliding plate 43, and is fixed above the paper pressing plate 20 by means of screws 45. The lower end of the sliding plate 43 is arranged against the paper pressing plate 20, and it is movably connected to the fixed plate 41 only through the long strip hole thereon. The side of the fixed plate 41 close to the guide post 30 is connected to the paper pressing plate 20 by means of two screws 45, and the side of the fixed plate 41 away from the guide post 30 is connected to the paper pressing plate 20 by means of one screw 45. The insert block 42 is horizontally arranged, one end of which is connected to the sliding plate 43, and the other end is suspended toward the side of the guide column 30, and the insert block 42 is located above the paper pressing plate 20 and below the fixed plate 41, so as to facilitate the vertical left and right movement of the sliding plate 43 along the fixed plate 41, thereby driving the insert block 42 to move horizontally left and right.

[0042] like Figure 5 As shown, the end of the insert block 42 close to the guide post 30 is constructed as an inclined slope structure, and its slope is in the same direction as the thread slope of the guide post 30, so that the top angle of the slope of the insert block 42 can be inserted between adjacent thread circles in the guide post 30, that is, interpolated into the thread ring to push against the guide post 30, so that the position of the paper pressing board 20 on the guide post 30 is fixed. The top surface of the insert block 42 is a flat plane, and its structure is arranged along the length direction of the paper pressing board 20.

[0043] like Figure 6 As shown, the fixed plate 41 is constructed as a flat plate structure, and its side is constructed as a single-level table structure, and its width at the end away from the guide column 30 is smaller than its width at the end close to the guide column 30. This structure facilitates the sliding plate 43 to be clamped on the single-level table thereon, and further facilitates the cooperation between the sliding block 43 and the fixed plate 41. It is not only simple in structure but also easy to operate.

[0044] like Figure 7As shown, the sliding plate 43 is vertically arranged on the paper pressing plate 20, and is provided with a long hole passed by the fixing plate 41; and a through hole for fixing the plug block 42 and a through hole for connecting with the screw 45 through the spring 44 are provided below it, and the plug block 42 is fixed to a side surface of the sliding plate 43 close to the guide column 30 through a connecting member similar to a screw structure.

[0045] like Figure 8 As shown, springs 44 connected to screws 45 are provided on both sides of the insert block 42 in the sliding plate 43. One end of the spring 44 is connected to the sliding plate 43, and the other end is connected to the screw 45 used to connect the side of the fixed plate 41 close to the guide column 30 and the paper pressing plate 20. That is, the other end of the spring 44 is connected to the screw 45 used to fix the fixed plate 41.

[0046] The entire fixing device can slide left and right in the groove 11 on the workbench 10 through the sliding key 12, and can also be directly removed, which is simple and convenient. When work is needed, first put the paper under the paper pressing board 20 after arranging it, and then adjust the height of the paper pressing board 20 so that the paper pressing board 20 just presses against the thickness of the paper, and then move the sliding plate 43 to insert the plug 42 into the threaded ring in the guide column 30 to press against the guide column 30 to fix the position height of the paper pressing board 20, thereby fixing the position of the paper and preparing for binding. When the binding is completed, the sliding plate 43 can be moved outward to separate the socket 42 from the guide column 30, and then the position of the paper pressing board 20 can be loosened, and the paper can be quickly taken out and evacuated from the workbench. The fixing device proposed in this application has a simple overall structure and is easy to operate. It can quickly and accurately press and fix the paper so that it can be stably placed on the workbench to ensure that the position of the paper is fixed and will not shift; it can also quickly and safely loosen the paper to make it leave the workbench, which is safe and highly operable, ensuring the uniformity and reliability of the binding quality.

[0047] A binding machine is provided with the fixing device as described above.
