[0002] like Figure 1 As shown, in the transplanter, the corrugated disc and the planting part on the transplanter are raised and lowered together. Since the rotation of the corrugated disc depends on the transmission shaft 19 with a cross knot connected to the clutch, when the corrugated disc 7 is lifted to the transmission shaft above 40 degrees, if the corrugated disc continues to rotate, the angle between the corrugated disc 7 and the power box is too large, resulting in the risk of the transmission shaft 19 being stuck or broken, thereby making it impossible for the corrugated disc 7 to rotate. At this time, the power is cut off, and other power will also be cut off, making it impossible for the transplanter to continue to operate.
