Two slide rails 5 are fixedly connected to the right side of the bottom of the fixed plate 1, and a dividing plate 4 is fixedly connected to the right side of the bottom of the fixed plate 1. The top of the dividing plate 4 is fixedly connected to the bottom of the two slide rails 5. The rear slide rail 5 is rotatably connected with a reciprocating screw 26, and a cutting knife 6 is arranged on the outer wall of the reciprocating screw 26. The front end of the outer wall of the cutting knife 6 is slidably connected with the inner wall of the front slide rail 5, and a first pulley 16 is fixedly connected to the rear end of the outer wall of the driving rod 15. The right side of the inner wall of the fixed plate 1 is rotatably connected with a second pulley 17, and the second pulley 17 and the first pulley 16 are connected through the inner side of the belt strip.

[0032] Specifically, the motor 2 drives the driving rod 15 to rotate and drive the driving toothed disc 10 to rotate. The driving toothed disc 10 rotates and pushes the power rod 19 to move. The power rod 19 drives the top block 21 to push the tooth block 18. The tooth block 18 is pushed to rotate the rotating disc 11 to squeeze the copper-clad laminate and drive the copper-clad laminate to move forward. Because the surface of the driving toothed disc 10 is three-sectioned, the push on the power rod 19 is limited, so it is pushed again and again. When the driving toothed disc 10 no longer pushes the power rod 19, the rubber band 23 pulls the power rod 19 back and no longer pushes the tooth block 18 to rotate the rotating disc 11. At the same time, the driving rod 15 drives the first pulley 16 to rotate and the second pulley 17 to rotate. The rotation of the second pulley 17 drives the first bevel gear 24 to rotate. The rotation of the first bevel gear 24 drives the second bevel gear 25 to rotate. The rotation of the second bevel gear 25 causes the reciprocating screw 26 to rotate and drives the cutting knife 6 to reciprocate on the slide rail 5 to cut the copper-clad laminate.

[0033] Embodiment 2:

[0034] As one of the optimized structural designs for Example 1, Figure 1-Figure 5 As shown, a bidirectional screw 13 is fixedly connected and rotatably connected to the outer wall of the adjusting groove, the bottom sides of two sliders 14 are threadedly connected to the outer wall of the bidirectional screw 13, the left end of the front side of the fixed plate 1 is rotatably connected to the rotating disk 11, the rear end of the rotating disk 11 is fixedly connected to the front end of the bidirectional screw 13, a through groove is opened in the middle of the power rod 19, the bottom of the dividing plate 4 is slidably connected to the collecting box 3, a handle is provided on the right side of the collecting box 3, and the outer walls of the handle and the crank 12 are provided with anti-slip stripes.

[0035] Specifically, the bidirectional screw 13 is rotated by shaking the rotating disk 11 to drive the two sliders 14 to slide, and the two cutting knives 8 are adjusted to cut the edges of the copper-clad laminate; the copper-clad laminate is collected in the collection box 3 after cutting; the anti-slip stripes arranged on the outer walls of the handle and the crank 12 increase the friction force, making it easier to grip; the groove is used to prevent the tooth block 18 from being blocked by the power rod 19 when the rotating disk 11 rotates.

[0036] Working principle: By shaking the rotating disk 11, the bidirectional screw 13 rotates and drives the two sliders 14 to slide, and the two edge cutting knives 8 are adjusted to cut the edges of the copper-clad laminate. The copper-clad laminate after edge cutting is placed on the follower roller 7, and the motor 2 is started to drive the drive rod 15 to rotate to drive the drive gear plate 10 to rotate, and the drive gear plate 10 rotates to push the power rod 19 to move, and the power rod 19 drives the top block 21 to push the tooth block 18. The tooth block 18 is pushed to make the rotating disk 11 rotate to squeeze the copper-clad laminate and drive the copper-clad laminate to move forward. Because the surface of the driving gear plate 10 is three-sectioned, the push on the power rod 19 is limited, so it is pushed again and again. When the driving gear plate 10 no longer pushes the power rod 19, the rubber band 23 pulls the power rod 19 back and no longer pushes the tooth block 18 to rotate the rotating disk 11. At the same time, the driving rod 15 drives the first pulley 16 to rotate, which causes the second pulley 17 to rotate. The rotation of the second pulley 17 drives the first bevel gear 24 to rotate. The rotation of the first bevel gear 24 drives the second bevel gear 25 to rotate. The rotation of the second bevel gear 25 drives the reciprocating screw 26 to rotate and drives the cutting knife 6 to reciprocate on the slide rail 5 to cut the copper-clad laminate.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
