AI Technical Summary
The nut plate of the existing abrasive wheel is easy to lose, which makes it impossible to disassemble and install the grinding wheel, causing inconvenience and safety hazards.
An installation component is inserted into the mounting hole of the base. A fixing plate is fixed to the end of the installation component. The fixing plate and the inner side of the mounting cylinder are provided with internal threads. The abrasive wheel can be quickly disassembled and fixed by connecting it to the connecting shaft of the angle grinder.
It enables quick assembly and disassembly of the abrasive wheel on the grinding tool, avoids the problem of losing the nut plate, and improves operating efficiency and safety.
