Working principle of wild boar clamp
The annular iron ring provides the clamping force of the spring clip, and the middle of the two clips in the middle is serrated, which outputs strong damage. Considering that the height of the clip is relatively low, it may pinch people's ankles. It is suggested that you must wear thick cotton socks, high-heeled hiking shoes and leggings when camping on wild roads to reduce injuries.
The white metal plate in the middle is the trigger device of the clip. Generally, two clips are pulled apart at 180 degrees and hung on a trigger linked with a metal iron plate. The feet of the prey step on the metal plate to trigger the release of the two clips, and the clips are driven by a ring spring to clamp the feet of the prey.
