[0027] Wherein, the outer wall of round cavity 203 is provided with several rows of side holes 206, for the radial extension of expansion rod 217, the expansion rod 217 is slidably connected in the side hole 206, and a plurality of point anchoring structure is formed, one end of the expansion rod 217 in the round cavity 203 is fixedly connected with the connecting column 218, the synchronous action of the expansion rod 217 in the same column is realized, the top and bottom of the connecting column 218 are rotatably connected with the round block 219, the sliding friction resistance is reduced, and the round block 219 is slidably connected with the arc groove 216. The curve design of arc groove 216 controls the extension length of expansion rod 217.

[0038] When the rotating rod 205 rotates, it will drive the connecting block 212 to rotate through the vertical groove 211, thereby making the guide column 213 slide in the circumferential groove 215. When the extension rod 217 extends from the side hole 206 for reinforcement, the soil breaking cone 214 is retracted into the soil insertion cone 201, and when the extension rod 217 is retracted into the circular cavity 203, the soil breaking cone 214 extends from the soil insertion cone 201, thereby making the soil breaking cone 214 not only assist in breaking the soil, but also be retracted into the vertical cavity 202 in the idle state to avoid injuring the user.
