In some alternative embodiments, a pallet 430 may be further provided on the lower pole 420, and the pallet 430 is mounted on the lower pole 420 in a horizontal state. Specifically, during installation, the supporting plate 430 is firstly installed on the lower supporting rod 420, and a fixed connection mode, such as welding, can be adopted between the supporting plate 430 and the lower supporting rod 420; the connection can also be detachable, such as a clamping connection. After the pallet 430 is mounted to the lower pole 420, the pallet 430 is positioned on the upper portion of the lower pole 420 and is not slid with each other. Then, the lower part of the lower pole 420 is inserted into the soil, when the lower pole 420 is inserted into the soil until the pallet 430 is closely attached to the ground, the lower pole 420 can not descend any more due to the resistance of the pallet 430 in the opposite direction, and at this time, the distance between the pallet 430 and the lower end of the lower pole 420 is the total depth of the lower pole 420 inserted into the soil.
