AI Technical Summary
The replacement of existing milling machine cutter heads and inserts is cumbersome and unsafe. The quick-release structure is prone to falling off during high-speed milling, leading to safety accidents.
The design combines a magnetic positioning structure and a threaded locking structure. The magnetic positioning structure is used for quick installation of the blade, while the threaded locking structure provides additional fixing force to prevent it from falling off.
It enables quick assembly and disassembly of the blades and efficient fixation, improving work efficiency and safety, and reducing the risk of blades falling off.
