DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be further described in detail below with reference to the drawings.

[0025] As Figures 1 to 5 shown, in order to achieve the technical effect of "coil holes with different spacings can be punched on the sketchbook according to different usage requirements", the structure and function of a coil type sketchbook punching device will be described in detail below;

[0026] A coil-type sketchbook hole puncher, including a placement bottom plate 11 and a lifting top plate 41. A sliding groove I 12 is provided on the placement bottom plate 11, and a sliding groove II 42 is provided on the lifting top plate 41. A plurality of sliding seats I 21 are slidably connected in the sliding groove I 12, and a plurality of sliding seats II 61 are slidably connected in the sliding groove II 42. A cutting hole is provided on the sliding seat I 21, and a cylindrical cutting tool 63 is fixedly connected to the sliding seat II 61. The plurality of sliding seats I 21 and the plurality of sliding seats II 61 correspond to each other, and the cylindrical cutting tool 63 can pass through the cutting hole at the corresponding position;

[0027] During use, stack the sketchbook papers to be punched on the placement bottom plate 11, drive the lifting top plate 41 to move, so that the lifting top plate 41 approaches the placement bottom plate 11, the sliding seat II 61 and the sliding seat I 21 approach each other, so that the cylindrical cutting tool 63 passes through the sketchbook paper and inserts into the cutting hole, thereby completing the cutting of the sketchbook paper;

[0028] Further, in order to position the sketchbook paper, a positioning plate 32 is slidably connected to the placement bottom plate 11; a support seat 13 is fixedly connected to the placement bottom plate 11, and a second lead screw 31 is threadedly connected to the support seat 13. The end of the second lead screw 31 is rotatably connected to the positioning plate 32;

[0029] When placing the sketchbook paper, stack the sketchbook paper on the placement bottom plate 11, and the end of the sketchbook paper abuts against the positioning plate 32. When it is necessary to adjust the position of the sketchbook paper, rotate the second lead screw 31. When the second lead screw 31 rotates, it drives the positioning plate 32 to move through the thread, thereby adjusting the position of the positioning plate 32 and further adjusting the position of the sketchbook paper;

[0030] Further, in order to facilitate the approach of the lifting top plate 41 to the placement bottom plate 11, a plurality of telescopic mechanisms 51 are fixedly connected to the lifting top plate 41, and the telescopic ends of the telescopic mechanisms 51 are fixedly connected to the placement bottom plate 11;

[0031] Start the telescopic mechanism 51. The telescopic mechanism 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism 51 drives the lifting top plate 41 to approach the placement bottom plate 11, so that the cylindrical cutting tool 63 passes through the sketchbook paper and inserts into the cutting hole, thereby completing the cutting of the sketchbook paper; Four telescopic mechanisms 51 are provided, and the four telescopic mechanisms 51 are respectively arranged at the four corners of the lifting top plate 41;

[0032] Further, in order to punch coil holes with different spacings on the sketchbook according to different usage requirements, first lead screws 22 are threadedly connected to both the left and right sides of the placement bottom plate 11, and the ends of the two first lead screws 22 are respectively rotatably connected to the sliding seats I 21 on both sides;

[0033] A compression spring I is fixedly connected between the sliding seats I 21 and the sliding seats I 21;

[0034] On the left and right sides of the lifting top plate 41, screw rods III 62 are threadedly connected respectively, and the end parts of the two screw rods III 62 are rotatably connected to the sliding seats II 61 located on both sides;

[0035] A compression spring II is fixedly connected between the sliding seats II 61 and the sliding seats II 61;

[0036] A plurality of cutting notches are arranged at the bottom of the cylindrical cutting tool 63;

[0037] When the screw rod I 22 is rotated, the screw rod I 22 drives the corresponding sliding seat I 21 to move through the thread when rotating, so that the two sliding seats I 21 on both sides approach or move away from each other. As Figure 3 shown, a compression spring I is arranged between the plurality of sliding seats I 21, and thus the distance between the plurality of sliding seats I 21 is adjusted. When the screw rod III 62 is rotated, the screw rod III 62 drives the corresponding sliding seat II 61 to move through the thread when rotating, so that the two sliding seats II 61 on both sides approach or move away from each other. As Figure 4 shown, a compression spring I is arranged between the plurality of sliding seats II 61, and thus the distance between the plurality of sliding seats II 61 is adjusted, so as to realize punching coil holes with different pitches on the sketchbook according to different usage requirements.
