On the basis of the technical scheme, the inner side wall of the through hole, which is close to the boss, can be matched with the outer side wall of the spring chuck.

On the basis of the technical scheme, the number of the dust suction ports is 9.

Advantageous effects

The utility model discloses well 9 even rings of impeller cloth can produce the spiral air current from bottom to top around the boss at this dust absorption nut along with the high-speed rotatory in-process of cutter axle, so the air current flow direction is more agreed in the design of spiral dust absorption mouth, and resistance when the sweeps that can significantly reduce rises has increased suction and has made the chip removal more thorough.

In the utility model, a spiral dust suction port is formed between two adjacent impellers, and the aperture of the dust suction port is gradually increased from inside to outside, thus realizing rapid and smooth chip removal; and the spiral dust suction port is formed by two adjacent impellers, the number of the dust suction ports cannot be reduced while the caliber of a single dust suction port is increased, the chip removal efficiency is high, and the chip removal performance is good when the large-diameter waste chips are treated or the chip removal speed is high.

The utility model discloses well top surface of impeller is higher than the top surface of boss, and impeller top surface and boss top surface can form the open chamber of an indent promptly, and the sweeps that processing produced can assemble earlier to above-mentioned open intracavity under the air current promotes, later discharges from the dust absorption mouth, so can avoid adding the sweeps that adds man-hour splashes everywhere, influences subsequent processing.

The utility model discloses simple structure, easy operation, processing low in manufacturing cost, impeller block and nut spare wherein can dismantle the connection, so can conveniently carry out thorough clearance to it after processing.
