[0033] The middle parts of the movable splint 42 and the fixed splint 4 are both arc-shaped structures. An elastic rubber strip 5 is provided on the side where the movable splint 42 and the fixed splint 4 are close to each other. The elastic rubber strip 5 not only protects the rhizome of Polygala tenuifolia, but also increases friction to prevent Polygala tenuifolia from sliding on the clamping mechanism and affecting its use.

[0034] An adapter seat 21 is fixedly installed on the handle 2, and a rotating handlebar 22 is rotatably installed on the adapter seat 21. A fixed column is provided at one end of the rotating handlebar 22, and the fixed column is fixedly connected to the end of the pull rope 43.

At this time, the fixed rod 1 is pushed to the ground by the handle 2. When the grounding plate 311 contacts the ground, the movable plug rod 31 is subjected to an upward force, and under the cooperation of the boss and the guide groove 32 on the fixed block 11, the movable plug rod 31 drives the cutting head 34 to rotate, so as to cut the root of Polygala tenuifolia.

[0038] When the cutting head 34 completes cutting of the root of Polygala, the fixed rod 1 and the clamping mechanism continue to move downward, which will drive the sharpened root of Polygala to be inserted into the soil. When the movable insertion rod 31 is completely immersed in the installation groove 3, the force on the rotating handle 22 is released. The rotating handle 22 will return to its initial position under the elastic force of the spring piece 23. The tension spring 13 pulls the rotating clamping plate 42 to rotate away from the fixed clamping plate 4, releasing the clamping effect on the Polygala, and the cutting work of Polygala can be completed. It is easy to use and improves the cutting efficiency.
