By placing the base cover on the ground to be marked, and then holding the movable rod, the worker uses their foot to step on the disc, causing the nails to be inserted into the ground, thus completing the assembly of the base cover. This design allows workers to complete the assembly of the base cover quickly and easily (converting the traditional manual rod insertion into lower limb force, which is both ergonomic and saves a lot of physical strength; a single step can achieve simultaneous fixation at multiple points). Secondly, the depth of the nails in the soil is controlled by the limiting ring, which prevents excessive sinking that would make retrieval difficult, and also avoids loosening of the mark due to insufficient depth, ensuring the stability of the positioning.

[0014] 2. By rotating the fastening rod, the side end of the fastening rod is separated from the movable rod. Then, the movable rod is adjusted up and down. After the position of the movable rod is determined, the fastening rod is rotated again to press and fix the movable rod, thereby completing the adjustment of the position and height of the movable rod.

[0015] 3. By pressing down the moving bar, the locking rod is rotated and positioned inside the arc-shaped plate. Then, the moving bar is released, causing the spring telescopic rod to push the moving bar up and down. The notch on the side of the moving bar can then connect with the bottom of the locking rod to lock the position of the locking rod. Through this structural design, the spring preload maintains a continuous locking effect, preventing accidental unlocking caused by operational vibrations and ensuring the long-term stability of the marking device in complex terrain.

[0025] like Figure 3 As shown, a limiting ring 14 is also provided on the bottom inner wall of the bottom cover 1 to limit the travel distance of the moving plate 4 as it moves downward.

[0026] Specifically, the base cover 1 is placed on the ground to be marked. Then, holding the movable rod 3, the worker steps on the moving plate 4 with their foot to insert the nail 5 into the ground, thus completing the assembly of the base cover 1. This design allows workers to quickly and easily complete the assembly of the base cover 1 (converting the traditional manual insertion rod into lower limb force, which is both ergonomic and saves a lot of physical strength; a single step can achieve simultaneous fixation at multiple points). Secondly, the depth of the nail 5 in the soil is controlled by the limiting ring 14, which prevents excessive sinking that would make retrieval difficult and avoids loosening of the mark due to insufficient depth, ensuring the stability of the positioning.

[0027] like Figure 1 As shown, the connecting sleeve 2 has a fastening rod 7 threaded on its side, and the side end of the fastening rod 7 presses against the movable rod 3. By rotating the fastening rod 7, the side end of the fastening rod 7 is separated from the movable rod 3. Then, the movable rod 3 is adjusted up and down. After the position of the movable rod 3 is determined, the fastening rod 7 is rotated so that the side end of the fastening rod 7 presses against and fixes the movable rod 3 again, thereby completing the adjustment of the position and height of the movable rod 3.

[0028] like Figure 1 As shown, a limiting strip 8 is provided on the outer side of the movable rod 3. The limiting strip 8 is slidably connected to the inner wall of the connecting sleeve 2. By setting the limiting strip 8, it can be ensured that the movable rod 3 will not rotate when it moves up and down, that is, the stability of the position of the marking plate at the top of the movable rod 3 is guaranteed.

[0029] like Figure 2 and Figure 3 As shown, a locking rod 9 is rotatably installed on the inner wall of the top of the base cover 1. The bottom end of the locking rod 9 can contact the center area of ​​the top of the moving plate 4. After the moving plate 4 moves down, the locking rod 9 can be rotated so that the bottom end of the locking rod 9 abuts against the top of the moving plate 4, thereby increasing the stability between the base cover 1 and the moving plate 4.

[0030] like Figure 1 As shown, an arc-shaped plate 10 is provided in the top center area of ​​the moving plate 4, and the bottom end of the locking rod 9 can contact the side of the arc-shaped plate 10. This design can increase the stability of the locking rod 9 in the top center area of ​​the moving plate 4.
