Under the action of the support seat, the operator only needs to control the drill bit to be inserted vertically into the ground during the process of using this solution, and does not need to bear the importance of the frame, motor and drill bit, which reduces the burden on the operator. During the process of drilling the drill bit into the ground , the frame slides down, and the compression spring is compressed, so that the distance between the frame and the ground is reduced, which is matched with the downward movement of the drill bit. During the downward movement of the drill bit and the frame, the specific depth of the downward movement of the drill bit can be obtained by observing the scale value at the junction of the frame and the support base, which is convenient to control and record the downward movement depth of the drill bit.

Further, the lower end of the drill bit is provided with several protruding thorns. During the drilling process of the drill bit, the spur can increase the cutting ability of the drill bit, thereby accelerating the drilling speed of the drill bit.

Further, the frame is provided with handrails. The operator can control the direction of the drill bit by controlling the handrail to ensure that the drill bit is perpendicular to the ground.

Further, a ground gripper is fixed on the bottom of the support base. The gripping claw makes the contact between the support seat and the ground firm, and avoids the support seat from slipping.
