[0007] Further, the dust absorption pipe is in arc structure, and the inlet end of the dust absorption pipe is towards the tool bit.

[0008] Further, the dust absorption pipe is in L type structure, and the inlet end of the dust absorption pipe is connected with annular hollow pipe, the annular hollow pipe is installed at the bottom of the cutter holder and is above the tool bit, and the annular hollow pipe is connected with a plurality of elbow pipes, the elbow pipes are around the tool bit, and the inlet end of the elbow pipe is opposite the tool bit.

[0009] Further, the negative pressure air pipe is connected with the vacuum conversion seat through a quick inserting straight thread air joint pc.

[0010] Further, an electromagnetic valve is connected between the vacuum generator and the negative pressure collection box.

[0011] Compared with the prior art, the utility model has the advantages that the utility model can suck the cutting waste produced during cutting in real time, and the cutting head does not need to be cleaned when not working, effectively solves the defects caused by the prior art, and the device principle is simple and low in cost.
