The driving motor 31 drives the rotating shaft 23 to rotate through the pulley 33 and the transmission belt 34. Since the clamping block 6 on the spacer sleeve 22 clamps the cutter 21, the cutter 21 will also rotate along with the rotating shaft 23. The seedling tray 10 slides under the support of the conveying roller 9, and the rear tray pushes the front tray, so that the seedling leaves enter the leaf shearing area of ​​the cutter rotating clockwise at high speed for cutting. Under the action of the seedling supporting rod 42 of the seedling supporting device 4, the seedling leaves in the cells of the seedling tray 10 are lifted up, so that the seedling leaves are better cut by the cutter to achieve an effective seedling cutting rate. This device can quickly cut the seedling leaves through the combined action of the cutter 21 and the seedling supporting rod 42.
