[0020] The dust generated during grinding can be drawn into the purification box 14 through the dust inlet pipe 22 by the negative pressure fan 15, and then the dust is adsorbed by the activated carbon balls 23, so that the purified gas is discharged through the through hole 16, thereby improving the environmental protection and practicality of the grinding device during use.

[0021] In this embodiment, as Figure 3 and Figure 4 As shown, a threaded rod 4 is fixedly connected to the output end of the drive motor 6.
