[0028] In the embodiment, the top of each column rod 1 is provided with a track groove 101 penetrating through the outside of the column rod 1, the recess inside the track groove 101 is provided with an adjusting rod assembly, a locking assembly is installed in the middle region inside the track groove 101, the locking assembly comprises a fixed block 6 and a fixed bolt 601 threadedly connected to the fixed block 6, the fixed bolt 601 extends into the inside of the track groove 101 and abuts against the corresponding adjusting rod assembly, and the limit block one 4 and the limit block two 5 are both metal blocks made of stainless steel, as outdoor parts, the limit block one 4 and the limit block two 5 made of stainless steel not only have high structural hardness, but also have high fixing effect and are resistant to rainwater corrosion.

[0029] Specifically, the track groove 101 is a rectangular cavity, the opening of the track groove 101 corresponds to the front and back of a row of limit block two 5, and the adjusting rod assembly is connected to a row of limit block two 5, the adjusting rod assembly moves up and down in the track groove 101, and simultaneously drives the corresponding limit block two 5 to move synchronously, so as to control the staggered distribution between a row of limit block two 5 and limit block one 4 to fix the protective net 2 attached to the outside of the column rod 1 at multiple points.

[0030] In the embodiment, the adjusting rod assembly comprises a connecting long rod 502, a sliding block 501 is connected on the rod of the connecting long rod 502 at equal intervals, the sliding block 501 is connected with a corresponding limiting block two 5 fixedly and correspondingly in front and back, and a circular hole 102 corresponding to the connecting long rod 502 is formed in the bottom surface of each track groove 101.

[0031] Specifically, the sliding block 501, the connecting long rod 502, the limiting block two 5 and the track groove 101 in the adjusting assembly, when the adjusting rod assembly moves to the lowermost end in the track groove 101, the lowermost end of the connecting long rod 502 is clamped in the internal groove of the corresponding circular hole 102, and the adjusting rod assembly in the track groove 101 is further limited and fixed.

[0032] In the embodiment, the bottom of each of the column rods 1 is provided with a positioning nail 3, and the column rod 1 and the positioning nail 3 are integrally cast, the drill bit of each layer of the positioning nail 3 is sequentially reduced in diameter from the bottom upwards, and the surface of each layer of the drill bit is provided with a spiral raised texture.

[0033] Specifically, the spiral raised texture of the positioning nail 3 has multiple significant effects. In the process of installing the column rod 1 of the protective fence to the grassland soil, the spiral raised texture of the positioning nail 3 first plays a role of assisting in breaking the soil. When the positioning nail 3 is inserted into the soil, the rotating texture is like the thread of a drill bit, which can more effectively break the soil and guide the positioning nail 3 to penetrate into the ground. Compared with the ordinary smooth surface drill bit, the soil breaking resistance can be reduced by about 30%, which greatly reduces the manpower and mechanical force required in the installation process.

[0034] In terms of enhancing stability, the spiral texture of the positioning nail 3 increases the friction between the positioning nail 3 and the soil. On the grassland, strong winds and collisions with livestock often occur, and the positioning nail 3 with the spiral raised texture can tightly grasp the soil. Tests show that the anti-pulling force of the positioning nail 3 with the spiral raised texture is increased by at least 40% compared with the positioning nail 3 without the spiral raised texture, effectively preventing the column rod 1 from tilting or shifting.

[0035] The working principle and use process of the utility model are as follows:

[0036] The limiting block one 4 and the limiting block two 5: through the staggered distribution of the limiting block one 4 and the limiting block two 5 in the opposite direction, the transverse steel wire on the protective net 2 is firmly fixed on one side of the column rod 1. The L-shaped part of the limiting block one 4 is overlapped on the transverse steel wire of the protective net 2, and the limiting block two 5 is pushed downward by the adjusting rod assembly to form a staggered fixed point with the limiting block one 4. This design realizes the multi-point fixing of the protective net 2, ensures the stability, and can effectively cope with the external force influence such as strong wind and collision of livestock on the grassland.

[0037] Adjusting rod assembly: The adjusting rod assembly is arranged to control the up and down movement of the limiting block two 5, which is staggered with the limiting block one 4, further enhancing the fixing strength of the protective net 2. The limiting block one 4 and the limiting block two 5 on each group of columnar rods 1 form multi-point fixing, thereby greatly improving the connection firmness effect of the protective net 2 and the columnar rods 1.

[0038] Stability of the columnar rod 1: The bottom of the columnar rod 1 is provided with a positioning nail 3 in the shape of a stepped drill bit, and the spiral protruding texture design brings significant effect. During the process of breaking the soil, the spiral protruding texture of the positioning nail 3 is similar to the thread of a drill bit, which can effectively reduce the soil breaking resistance, making the installation of the columnar rod 1 more labor-saving. When installing, rotating the positioning nail 3 can make it penetrate into the soil, enhancing the fixing effect. At the same time, the spiral protruding texture also increases the friction between the positioning nail 3 and the soil, improving the anti-pulling force by at least 40%, ensuring that the columnar rod 1 will not tilt or shift under adverse weather conditions or external forces.

[0039] Adjusting function and fixing reliability: The track groove 101 and the adjusting rod assembly: The top of the columnar rod 1 is provided with a track groove 101 penetrating its outer side, which is a rectangular cavity with an adjusting rod assembly installed inside. The adjusting rod assembly drives the limiting block two 5 to move up and down in the track groove 101, and the sliding block 501 slides inside the groove, making the limiting block two 5 cooperate with the limiting block one 4 to complete the multi-point fixing of the protective net. At the same time, the bottom of the track groove 101 is also provided with a round hole 102, when the adjusting rod assembly is lowered to the lowest end, the lower end of the connecting rod 502 is inserted into the round hole 102, limiting and fixing the adjusting rod assembly, further increasing its stability.

[0040] Locking assembly: The track groove 101 is also installed with a locking assembly, which is composed of a fixed block 6 and a fixed bolt 601. The fixed bolt 601 extends into the track groove through threaded connection, and abuts against the adjusting rod assembly, ensuring the positioning and fixing of the adjusting rod assembly in the track groove. This design makes the adjusting assembly more reliable when adjusting the fixing of the protective net, reducing the possibility of loosening or shifting.

[0041] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments. However, any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still falls within the protection scope of the present application.
