AI Technical Summary
During use, the nut of the existing dicing blade is prone to loosening, causing the blade to wobble and affecting cutting accuracy and stability.
The blade body is made with ceramic binder and features a design with a limiting rod and a snap-fit rod. Through the cooperation of the rotating shaft, connecting plate, and fixed plate, the limiting rod slides and adheres to the outside of the fixed plate for fixation, and the snap-fit rod engages with the limiting rod to prevent the fixed plate from loosening due to inertia, ensuring that the blade body is securely installed.
This effectively avoids the shaking problem caused by loose nuts, and improves the installation stability and cutting accuracy of the dicing blade.
