This utility model relates to the field of livestock and poultry isolation and protection fence technology, and discloses a foldable livestock and poultry isolation and protection fence for livestock farms, including fence one and fence two. This foldable livestock and poultry isolation and protection fence for livestock farms, through a set stabilizing component, allows the cylinder and connecting block to rotate relative to each other when fence one or fence two is flipped. This pushes the locking plate and stabilizing block to move against spring one, causing the short rod and ring to rotate, achieving synchronous radial movement of all components. When the locking plate is parallel to the contact groove, spring one resets, which in turn drives all mechanisms to reset, allowing the locking plate to enter the contact groove. After adjusting the angle, pulling the pull plate disengages the insert rod, and rotating the connecting plate and the rotating ring causes the through hole and the sliding rod to interlock. The inner wall of the rotating ring restricts the movement of the sliding rod, achieving interlocking of the fence. When the connecting plate rotates, the movable column, under the action of spring two, abuts against or engages with the stabilizing groove, preventing self-rotation, thus achieving folding. The angle can be adjusted to a suitable level for convenient use.
