AI Technical Summary
Existing paper cutters lack positioning and automatic correction functions, which makes the paper easily shift or tilt during the cutting process, reducing the cutting accuracy.
The first and second positioning mechanisms work together to position the paper by pushing the L-shaped frame to move and the clamping plate to move closer. The paper is then limited by the lifting plate and spring rod. Combined with the collection mechanism, automatic correction and paper collection are achieved.
It improves the precision and efficiency of paper cutting, ensures that the paper does not shift during the cutting process, and enhances the stability and automation of cutting.
