The present invention has a plurality of limiting devices distributed on the upper part of the inner drill rod body. The limiting clamping column is located at the upper part of the upper sand table, the limiting clamping column corresponds to the limiting clamping slot, and a lower drill bit is provided at the bottom end of the inner drill rod body, and the lower drill bit is located at the lower part of the lower sand table. When the inner drill rod body is extended into the outer cylinder, it is connected to the outer cylinder to form a combined drill bit assembly through the connection between the limiting clamping column and the limiting clamping slot. In this way, when the pistol drill drives the inner drill rod body to rotate, the inner drill rod body rotates and drives the outer cylinder to rotate through the connection between the limiting clamping column and the limiting clamping slot, thereby realizing the unified rotation of the combined drill bit. A handle is provided on the outer side surface of the top of the outer cylinder of the present invention, and the upper part of the handle is a T-shaped structure, and the lower part is bent and connected to the outer side surface of the outer cylinder, so that it is convenient for personnel to take the outer cylinder out of the ground after the tree is planted.
