Examples

Referring to fig. 1 to 3, the present embodiment provides a novel cutting mechanism 1000. The novel cutting mechanism 1000 includes: a feeding device 100 and a cutting device 200. The cutting device 200 includes a base plate 210, a pressing post 220, a tool holder 230, a cutter, a first driver 140, and a second driver.

The end surface of one end of the positioning post 212 close to the pressing post 220 is processed for anti-skid treatment. Through the design, the positioning column 212 embedded in the substrate 210 is matched with the pressing column 220 to fix the material, so that the substrate 210 can be prevented from deforming. On the other hand, the positioning post 212 subjected to the anti-slip treatment not only can improve the fixing effect on the material, but also can directly knock the positioning post 212 out of the substrate 210 for replacement when the positioning post 212 is worn.
