At the same time, the third flat gear 31 is meshed and connected with the first tooth block 24 on the outer side of the rotating ring 23 and the second flat gear 29 on the outer side of the fourth rotating rod 28. When the rotating ring 23 rotates, the second flat gear 29 can be driven to rotate synchronously through the third flat gear 31, so that the fourth rotating rod 28 fixedly connected to the second flat gear 29 can be driven to rotate synchronously between the two circular baffles 22, and the cutting knife 30 fixedly connected to the bottom of the fourth rotating rod 28 can be driven to rotate with the fourth rotating rod 28 as the center. At this time, the cutting knife 30 will rotate out of the outer side of the circular baffle 22 from between the two circular baffles 22 and perform the grass cutting operation. When the cutting knife 30 is rotated to be perpendicular to the center of the circular baffle 22, the cutting range of the cutting knife 30 is maximum. At the same time, the cutting knife 30 can cut within the range of movement from extending from the circular baffle 22 to rotating to be perpendicular to the center of the circular baffle 22, thereby adjusting the cutting range of the cutting knife 30 and improving the flexibility of weed cutting.

[0036] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.
