Bean clip, bag clip

See a lot of clips, they can not hold the bag well, it is easier to fall off, so there is no way to design one.The tooth-like structure has a stronger bite force and increased friction, making it difficult to fall off during use.Both horizontally and vertically can be clamped very firmly, and the clamp opening can be clamped on the part that needs to be clamped, which is very convenient.Double shrapnel, more elasticity, more bite.
