Yarn tensile strength testing device

Abstract

The utility model belongs to the technical field of yarn strength testing, and particularly relates to a yarn tensile strength testing device which comprises a strength tester and a limiting groove formed in the front side wall of the strength tester, two clamps are assembled on the front side of the strength tester, and the clamp on the lower side is movably connected with the limiting groove; the clamp comprises a cylinder, a plurality of fixing plates are fixedly connected to the side wall of the cylinder, annular plates are arranged between the fixing plates, and a control assembly is arranged in an inner cavity of the cylinder. And the control assembly comprises a screw rod rotationally connected to the inner wall of the cylinder, threads on the side wall of the screw rod are distributed in a multi-section mode, the side wall of the screw rod is in threaded connection with a thread sleeve, and the side wall of the thread sleeve is fixedly connected with a connecting plate. Yarns can be connected in a multi-circle winding mode, and the phenomena of separation, looseness or breakage are avoided.
