[0003] After the production of knotless nets is completed, tensile testing equipment is often required. The tensile testing equipment can accurately measure the tensile strength of the knotless net to ensure that it can meet the requirements of actual use.

For example, the surface of the knotless net made of polyethylene material is usually relatively smooth and it is easy to slip in the clamp. The slippage of the knotless net means that the force conditions have changed during the test, thereby reducing the accuracy of the test data. Therefore, a tensile testing equipment for knotless net production is proposed to address the above problems. Utility Model Content
