In order to facilitate disassembly and assembly, the transparent shell 11 is assembled by two parts through rivets, one part is a semicylinder with two flat ends, and the other part is a semicylinder with a conical end, and the two parts are both embedded with light emitting parts.

[0049] The boron nitride processing and polishing device further comprises a protective cover 50, which is arranged outside the clamp 10, the rotating shaft 32 and the chuck 33, and is connected with the motor 31 shell of the motor 31, so as to avoid that the operator's clothes or sundries are accidentally rolled into the machine during rotation.
