[0031] like Figure 1-5 As shown, a cylinder 10 is arranged on the top of the base plate 1, and the output shaft of the cylinder 10 is movably embedded in the interior of the limiting kit 2. The output end of the cylinder 10 is linked to the outer surface of the moving slider 8, and the output shaft of the cylinder 10 will drive the moving slider 8 to move.

[0032] like Figure 1-5 As shown, a connecting rod 11 is fixedly connected to one side of the inclined sliding block 5, and a punching rod 12 is fixedly connected to the side of the connecting rod 11 away from the inclined sliding block 5. A first fixed plate 13 is movably sleeved on the outer surface of the punching rod 12. Under the connecting action of the connecting rod 11, the two punching rods 12 will clamp and punch inward at the same time.

[0033] like Figure 1-5As shown, the bottom of the first fixed plate 13 is fixedly connected to the top of the base plate 1, the outer surface of the punching rod 12 is movably sleeved with the second fixed plate 14 on one side away from the first fixed plate 13, and the bottom of the second fixed plate 14 is fixedly connected to the top of the base plate 1. The punching rod 12 is movably embedded in the first fixed plate 13 and the second fixed plate 14 respectively to make the movement more stable.

[0034] like Figure 1-5 As shown, a rebound plate 15 is fixedly sleeved on the outer surface of the punching rod 12, and the outer surface of the first fixed plate 13 is arranged on one side of the rebound plate 15. A spring 16 is movably sleeved on the outer surface of the punching rod 12, wherein the spring 16 sleeved on the punching rod 12 is respectively arranged between the first fixed plate 13 and the rebound plate 15.

Under the limiting effect of the wedge groove 7 on the wedge block 9, the two inclined sliders 5 will move in the sliding groove 3 opened by the limiting kit 2. Then, under the limiting effect of the limiting groove 4 on the sliding bar 6, the two inclined sliders 5 will move in opposite directions along the limiting groove 4 at the same time. When the two inclined sliders 5 move inward at the same time, under the connecting effect of the connecting rod 11, the two punching rods 12 will clamp and punch inward at the same time, and punch and slot the packaging box sleeved on the pressure plate 19. The clamping and pressing structure enables the single cylinder 10 to clamp and punch both sides of the cardboard at the same time. The punching rod 12 is movably embedded in the first fixed plate 13 and the second fixed plate 14 to make the movement more stable, wherein the spring 16 sleeved on the punching rod 12 is respectively arranged between the first fixed plate 13 and the rebound plate 15, and the elastic action of the spring 16 can make the punching rod 12 have a quick rebound effect after punching, and prepare for the next punching, so that the punching efficiency of the device is high and suitable for long-term use. When the punching rod 12 is pushed forward, the punch 17 will press the packaging box to open the groove to complete the processing of the easy-tear line, and the positioning rod 18 in the punch 17 will be embedded in the positioning hole 20 when pushed forward to realize precise slotting and positioning.
