[0025] Specifically, in the process of digging lotus roots, the motor 8 will drive the gear 9 to rotate, and the gear 9 will further drive the gear 2 10 on one side to rotate. The gears 2 10 on both sides realize reverse synchronous rotation through the meshing structure. As the gear 2 10 rotates, the fixing rod 13 fixed on the gear 2 10 will drive the clamping plates 14 on both sides to clamp inwards, which can effectively fix the lotus root.
