A device for entrapment animal

The utility model discloses a device for entrapment animal belongs to entrapment equipment field. When the bait is bitten into to the animal, hang the inclined to one side core rod of line pulling, the pulling force that makes inclined to one side core rod overcome the elasticity rope rotates round the pivot. At this moment, the stay cord is realized tightening up in the pivot by the part winding,and then makes the go -between remove, extracts three bolt through the stay cord. Two weights and straight -bar fall under the action of gravity, and pulling force is exerted from both sides to the elasticity ring through connecting the rope to the weight, and the restriction that makes the deformation of elasticity ring and break through rope pressing plate gets into the contraction state, and the top that the straight -bar fell back elasticity ring also begins the shrink and breaks away from from the below opening of opening ring. The shown state of final elasticity ring shape image forming, the function is realize
