The upper end of the vertical slide rod 7 extends to the upper side of the rectangular positioning frame 1 and is fixedly connected to the limiting plate 8. The vertical slide rod 7 and the rectangular positioning frame 1 slide relative to each other in the vertical direction. A spring 9 is sleeved on the outside of the vertical slide rod 7 between the rectangular positioning frame 1 and the angle steel side frame 2.

[0029] The pressing mechanism includes a touch frame 10 and a pressing rod 11. The touch frame 10 is fixedly mounted on the upper side of the rectangular positioning frame 1 and is located on the rear side of the connecting plate 3. The pressing rod 11 is fixedly mounted on the inner side wall of the U-shaped frame 4 and the lower side of the pressing rod 11 can contact the upper side of the touch frame 10.

[0030] The counterweight adjustment includes an external thread structure 12, which is located at the lower outer end of the handle 5, and a counterweight block 13 is threadedly connected to the outer side of the external thread structure 12.

[0031] The connecting plate 3 is fixedly connected to the limiting rod 14, which is located on the side of the U-shaped frame 4 away from the touch frame 10. The limiting rod 14 can restrict the position of the U-shaped frame 4.

[0032] A protective glove 15 is fixedly fitted on the upper outer side of the handle 5, and the protective glove 15 has anti-slip stripes on the outer side; the protective glove 15 allows construction workers to grip the handle 5 more comfortably.

[0033] The U-shaped frame 4 has a first rotating shaft 16 at both its lower left and right ends in the left and right direction. The middle of the outer side of the first rotating shaft 16 is connected to the lower end of the U-shaped frame 4. One end of the first rotating shaft 16 is fixedly connected to the connecting plate 3 on the same side, and the other end of the first rotating shaft 16 is threadedly connected to a first limiting nut 17. The first rotating shaft 16 ensures the smooth rotation of the U-shaped frame 4. The first limiting nut 17 facilitates the installation and disassembly of the U-shaped frame 4.

[0034] The movable wheel 6 has a second rotating shaft 18 passing through its middle part in the left-right direction. The middle part of the outer side of the second rotating shaft 18 is connected to the movable wheel 6. One end of the second rotating shaft 18 is fixedly connected to the angle steel side frame 2, and the other end is threadedly connected to a second limiting nut 19. The setting of the second rotating shaft 18 can ensure the smooth rotation of the movable wheel 6. The setting of the second limiting nut 19 can facilitate the replacement of new movable wheels 6.

[0035] Working principle:

[0036] When moving the tool, first grasp the handle 5, making an angle of approximately 60 degrees between the U-shaped frame 4 and the rectangular positioning frame 1, then push forward to cause the moving wheel 6 to roll along the ground, thus moving the tool. When the rectangular positioning frame 1 moves to the set mark position, slowly release the handle 5. Under the action of gravity, the U-shaped frame 4 and the handle 5 will flip downwards. After the U-shaped frame 4 drives the downward pressure rod 11 to flip downwards, the downward pressure rod 11 touches and presses down on the contact frame 10. The contact frames 10 on both sides together press down on the rectangular positioning frame 1, causing the rectangular positioning frame 1 to move downwards and compress the spring 9. When the rectangular positioning frame 1 moves down to contact the ground, the U-shaped frame 4 and the handle 5 stop flipping, and the U-shaped frame 4 just avoids the rectangular positioning frame 1. The tool is positioned directly above the rectangular positioning frame 1, facilitating the spraying of markings onto the ground. When encountering an obstacle, the tool can use the handle 5 to flip the U-shaped frame 4 upwards until it contacts the limiting rod 14 (at this point, the angle between the U-shaped frame 4 and the rectangular positioning frame 1 is approximately 90 degrees). Then, the entire tool can be lifted using the handle 5 to allow it to pass over the obstacle. The tool can be moved by rotating the counterweight 13, thereby adjusting the center of gravity of the handle 5. This allows the weight of the U-shaped frame 4 and the handle 5 to press the rectangular positioning frame 1 down to contact the ground via the pressing mechanism, while ensuring that the rectangular positioning frame 1 and the angle steel side frames 2 on both sides do not tilt upwards, thus ensuring stable construction of the markings.

[0037] In summary, this tool can be moved by the rolling of the movable wheel 6, ensuring convenient movement, saving the physical strength of construction workers, and improving construction efficiency. During movement, the rectangular positioning frame 1 can be lifted off the ground by the elastic reset mechanism to ensure smooth movement. When it is moved to the set position, the rectangular positioning frame 1 can be pressed down to contact the ground by the gravity of the U-shaped frame 4 and the handle 5 and the cooperation of the pressing mechanism, thereby ensuring the accuracy of the marking work and the construction quality.

[0038] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
