Description

Technical Field

[0001] This utility model relates to the field of grassland fencing technology, specifically a modular, quick-installation, multi-aperture adjustable grassland fencing device. Background Technology

[0002] Fences play an indispensable role in every corner of our lives. Whether it's construction sites, residential areas, factory parks, or fences between lawns and roads, they all serve to isolate and protect. These fences separate construction areas from the outside world, ensuring the smooth progress of construction and the safety of passersby. In the security field, they block uninvited guests and protect the safety of internal property and personnel. On municipal roads, fences guide traffic flow and ensure the orderly passage of pedestrians and vehicles. In power facilities, fences isolate dangerous areas and prevent people from approaching high-voltage equipment and other potential hazards. They can also prevent pedestrians from crossing and trampling on the green environment. Traditional fences, with their seemingly "reliable" appearance, are widely present in various scenarios and have become a common sight. However, behind this widespread application, traditional fences actually hide many problems that urgently need to be solved. Common fences cannot be quickly installed and fixed during use, and the positions of the holes in traditional fences are mostly fixed, making it impossible to adjust them according to the actual installation situation, which is quite inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a modular, quick-installation, multi-aperture adjustable fence device for grasslands, in order to solve the problems mentioned in the background art of fences being inconvenient to install quickly and inconvenient to adjust the aperture of the fence.

When installing the fence, the main upright can be easily hammered or driven into the soil of the grass by the block-shaped protrusions. The inclined design of the insertion head and the elastic metal plate can easily break up the soil under the grass. Then, the tool can be inserted into the insertion hole and the rotating rod can be rotated. The rotating rod drives the auger to rotate, so that the threaded drill rod can rotate and screw into the soil of the grass. The auger can push open the elastic metal plate, so that the elastic metal plate can be pushed open and embedded in the soil, increasing the anti-slip and firmness. There is no need to use a cement foundation, which improves the convenience and firmness of the installation and greatly reduces the installation time. 2.
