A weeding tool is used in coordination with a tool machine and comprises a main rod and a weeding mechanism. The main rod is provided with a self-rotating shaft extending in the vertical direction. The weeding mechanism comprises a drilling rod and at least one blade. The drilling rod is connected with the main rod, extends along the vertical direction, and is provided with a tip end away from the main rod, and the tip end narrows from the direction away from the main rod to the main rod. Each blade is roughly in a plate shape, extends from the drilling rod to the direction away from the drilling rod, and is provided with a connection side for connecting the drilling rod and a blade edge connected with the connection side. The connection side extends in an inclined manner with respective to a horizontal plane, and the blade edge is used for cutting and roughly points to the horizontal direction. The main rod is detachably connected with the tool machine, and is controlled by the tool machine to drive the weeding mechanism to rotate around the self-rotating shaft, so as to perform weeding and soil loosening works.
