Preferably, described installation portion is rectangular slab, and the minor face of installation portion is connected with the circumference of clamping part; The quantity of described installation portion is 3.
Preferably, described clamping part and installation portion are formed in one.
Preferably, the second through hole on described each installation portion all along the long side direction of installation portion be one row arrangement.
The utility model compact conformation, materials are saved, and install stable, by upper cover plate and the clamping of lower cover and the location of mandrel, effectively can avoid emery wheel blank to be processed distortion and burr, make the endoporus machining accuracy of emery wheel blank to be processed higher.
