[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] The working principle of the utility model is as follows: when the tool is grinding the outer edge of the workpiece, the electric hydraulic rod 18 is started to make the rotating ball 20 apply force to the adjustment plate 17, so that the dust removal port 14 is opened, and the fan 13 is started to blow air into the protective cover 2 through the dust removal port 14 and blow away the dust.
