[0037] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0038] Embodiment: According to the drawings in the specification, one end of the lever is inserted into the cylinder 4. At this time, one end of the lever is located in the inner cylinder 15. The third electric push rod 19 is started. The third electric push rod 19 pushes the clamping block 20 to feed, so that the clamping block 20 performs three-point centering clamping on the lever. The drive motor 24 is started. The drive motor 24 drives the gear 25 to rotate.

The vacuum pump 31 evacuates the collection box 30 through the conduit, thereby generating a negative pressure in the pipe 36. The debris in the processing box 5 can fall along the funnel groove 34 to the through hole 35. The negative pressure generated by the pipe 36 can absorb the debris at the through hole 35, so that the debris enters the collection box 30, and is blocked by the filter 32 to prevent the debris from entering the vacuum pump 31. The staff can regularly open the inspection door 33 to clean the debris in the collection box 30;
