Preferably, the support blade length is one sixth to one quarter of the blade length.

Preferably, the blade is helically disposed on the connecting rod.

Preferably, the drill bit comprises a connecting platform, a drill body for drilling the ground is arranged at the lower end of the connecting platform, and a first connecting platform and a second connecting platform for fixing blades are arranged on the side face of the connecting platform.

Preferably, the first connecting table is movably provided with a first blade, and one end of the first blade is provided with a tooth socket for loosening the soil.

Preferably, a second blade is movably arranged on the second connecting table, and a flat blade for scraping soil is formed at one end of the second blade.

Preferably, spiral blades are arranged on the outer wall of the drill body in a surrounding mode.

Preferably, the blade segment abuts against one end of the first blade, and the lower end face of the support blade abuts against the end face of the second blade.

Preferably, the first connecting table and the second connecting table are obliquely arranged on the side surface of the connecting table,

preferably, one end of each of the first and second connection stages is provided with a cutting edge.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

1. compare with current ground auger, the ground auger of this application has increased a support blade on the connecting rod, supports the blade lower extreme and is connected with the second blade, plays the effect of supporting the second blade, prevents to take place to warp the emergence of the circumstances such as damage at drilling process, second blade, and the quality of the support blade itself that increases simultaneously is very little, can guarantee that ground auger has light in weight, advantage that intensity is high.

2. The utility model provides a first blade and second blade are the activity setting on the drill bit, because the wearing and tearing of ground auger are very fast, when the drill bit needs to be changed, only need change first blade and second blade can, such design enables the true problem life-span of drill bit more permanent, and it is also more convenient to use simultaneously.
