Problems solved by technology

[0003] 1. Most of the existing devices cut in a straight line, and the contact area between the blade and the circuit board is relatively large, which not only easily causes wear to the blade, but also easily causes damage to the circuit board, and the cutting efficiency is also slow;
[0004] 2. The existing device needs to fix the circuit board during the cutting process, the fixing efficiency is slow, and it is difficult to adjust the fixing force, which makes it easy to damage the circuit board
