The clamping claw with high hardness, and intermittent cutting, so that when the cutting depth and cutting amount is small, the cutting speed is not too high.
因卡爪硬度较高，又系断续切削，所以修正时切削深度和走刀量要小，切削速度也不宜太高。

The process of clamping and self-locking clip of seed-filling has been studied, and built a model on the seed-filling speed.
研究了夹持自锁取种机构的充种过程，建立了充种速度模型；
