The fixing nail 3 is a straight rod nail with a pointed lower end, and is wedged into the ground in a knocking mode to fix the first base 11. Preferably, the first base 11 is provided with a through hole for accommodating the fixing nail 3, and a head portion with a diameter larger than that of the fixing nail 3 is arranged above the first base 11 at the upper end of the fixing nail 3.

As shown in fig. 8 and 9, a leveling assembly for adjusting the levelness of the first leveling plate 12 is disposed between the first leveling plate 12 and the first base 11. Horizontal adjustment subassembly including set up respectively in the vertical adjusting bolt 51 of spirit level 4 preceding, back both sides and be located the horizontal adjusting bolt 52 of spirit level 4 left and right both sides, vertical adjusting bolt 51 and horizontal adjusting bolt 52 respectively with first level (l) ing board 12 threaded connection, the lower extreme of vertical adjusting bolt 51 and horizontal adjusting bolt 52 support and lean on the side of going up of first base 11.

Thus, during construction, the first base 11 is firstly placed at a proper position, and then the fixing nail 3 is knocked, so that the fixing nail 3 is wedged into the ground to realize the fixing of the first base 11. Due to the difference of the knocking force, the first base 11 cannot be leveled. Therefore, it is required to level the first leveling plate 12 by adjusting the leveling assembly, and the finally adjusted first leveling plate 12 will have a certain inclination with respect to the first base 11. When adjusting the levelness of the first level adjusting plate 12, it is only necessary to adjust the protruding length of the adjusting bolt while observing the air bubbles in the level 4.
