An upper handle 128 is fixedly provided at the top of the mounting column 123, and a side locking pin 129 is threaded into the top of the blade holder slider 121. The inner end of the side locking pin 129 abuts against the surface of the upper arm of the horizontal slide frame 103. This facilitates auxiliary limiting and fixing during assembly and use, making the cutting more stable.

[0029] In a more detailed embodiment, the left abutment 140 and the right abutment 150 are configured similarly. The left abutment 140 includes a side abutment seat 141 sleeved on the outside of the transverse slide 103, and a longitudinal abutment beam 142 is fixed between the two sets of side abutment seats 141. A lifting rod 143 is inserted through the middle of the longitudinal abutment beam 142, and a lower beam 145 is fixed to the lower end of the lifting rod 143. A lower abutment bar 146 is supported below the lower beam 145. A spring 144 is sleeved on the surface of the lifting rod 143, and the spring 144 is located at... Between the lower beam 145 and the longitudinal beam 142, it is convenient to limit and clamp the cardboard on both sides during use, making subsequent operations more convenient. The bottom of the lower abutment bar 146 is arc-shaped, and the top of the lifting rod 143 is fixed with an upper handle 147.

The lower fixing block 170 is fixed to the front and rear sides of the end of the dividing table 100 near the left upright 102. The bottom of the lower slider 160 is fixed with a lower screw pin 161, which is inserted into the dividing table 100. The lower end of the lower screw pin 161 is threaded with a lower nut 162. The bottom of the lower slider 160 is correspondingly provided with a lower sliding strip 163, which is engaged inside the dividing table 100. The front and rear sides of the dividing table 100 are provided with sliding grooves 164 corresponding to the sliding strip 163 and the lower screw pin 161. In this way, it is convenient to limit and support the corrugated cardboard in the front and rear during use, making the operation more convenient.

[0031] Working principle: During assembly and use, when processing and cutting corrugated cardboard, the left side of the cardboard is placed against the lower part of the limiting baffle 110. Then, with the cooperation of the lower slider 160 and the lower fixing block 170, the front and rear are limited and supported. Further, pulling the upper handle 147 facilitates the raising of the left abutment 140 and the right abutment 150, which then facilitates the clamping of the corrugated cardboard. Then, according to the cutting needs, the cutting knife holder 120 is moved to the required cutting position with the assistance of the alignment light 130. Then, the side locking pin 129 is tightened for quick and accurate positioning and high-precision cutting. Then, pressing the upper handle 128 facilitates the cutting knife 127 to cut the cardboard, making operation more convenient and improving cutting accuracy. Then, pulling the baffle handle 114 facilitates the raising and lifting of the limiting baffle 110, and then lifting the corresponding left abutment 140 and right abutment 150, which facilitates the removal of the cardboard from the left side, making operation more convenient. The operation ends here.
