The fixed seat 81 squeezes the first spring 85. At the same time, the fixed seat 81 and the guide block 86 slide relative to each other. Under the elastic action of the first spring 85, a downward acting force will be given to the pressure rod 82 and the pressure block 83, which can make the pressure block 83 press down the cardboard to realize the positioning of the cardboard, effectively preventing the offset of the cardboard during the cutting process from affecting the punching effect. Then, the mounting plate 5 drives the cutter 6 to move downward to cut the cardboard.

[0026] When it is necessary to adjust the positioning position, horizontally push the fixed seat 81. The fixed seat 81 drives the connecting rod 91 to move horizontally. The connecting rod 91 drives the ball 94 to move horizontally. The ball 94 will slide along the arc surface of the groove 93. The groove 93 will squeeze and push the ball 94 downward. The ball 94 will drive the slider 95 to slide along the connecting rod 96. The slider 95 will squeeze the second spring 97, which can separate the ball 94 from the groove 93. As the connecting rod 91 moves, the connecting rod 91 drives the limit block 92 to slide along the mounting plate 5. Subsequently, under the elastic action of the second spring 97, the slider 95 and the ball 94 can be pushed upward to reset, enabling the ball 94 to be reset and inserted into the groove 93 at another position, realizing the cooperation between the ball 94 and the groove 93 at different positions, and thus adjusting the horizontal position of the fixed seat 81 to conveniently adapt to the positioning punching of cardboard of different sizes.
