Description

Technical Field

[0002] Nowadays, fences are often used in farms to monitor different types of livestock in different areas. In order to prevent livestock from breaking through the fences and escaping, ropes with metal wires are often wrapped around the fences, and the metal wires are electrified. When livestock collide with the fences, they will come into contact with the electrified metal wires and feel an electric shock. This kind of fence with electrified ropes has a strong deterrent effect on livestock and can effectively prevent livestock from escaping and invasion of external organisms. At present, the installation of electrified ropes on fences is still done manually, and manual installation of electrified ropes is dangerous and inefficient.
