[0002] With the development of animal husbandry, especially in vast areas such as grasslands and pastoral areas, wire fences, as important facilities for preventing livestock from escaping and defining the range of pastures, have been widely used. A wire fence tightener is a tool specifically used to tighten and fix wire fences. It adopts mechanical or hydraulic principles. By applying appropriate force, the wire of the wire fence is tightened and ensured to maintain a stable state. By using the wire fence tightener, the tightness of the wire fence can be ensured, preventing it from loosening due to wind, animal pressure or other environmental factors, thereby improving the stability and safety of the fence. The wire fence tightener is widely used in the fields of animal husbandry, agriculture, land resource management, etc., and plays an important role.
[0003] At present, due to the influence of extreme weather such as wind and sand, the current wire fence tightener is more likely to loosen, resulting in the loosening or even falling off of the wire of the fence. The long-term loose wire of the fence is more vulnerable to damage and wear due to relaxation, reducing the service life of the wire fence, frequent replacement, and increasing maintenance costs. Content of the Utility Model
[0004] The purpose of the utility model is to provide a tightener for wire fence installation to solve the problems mentioned in the above background technique that due to the influence of extreme weather such as wind and sand, the wire fence tightener is more likely to loosen, resulting in the loosening or even falling off of the wire of the fence. The long-term loose wire of the fence is more vulnerable to damage and wear due to relaxation, reducing the service life of the wire fence, frequent replacement, and increasing maintenance costs. To achieve the above purpose, the utility model provides the following technical solution: A tightener for wire fence installation, including a first steel plate, in the middle of the back surface of the first steel plate is provided with a winding assembly.
