Then, one end of the fiber to be measured is wound around the upper winding wheel 2. Then, the upper handle 5 is released, and the upper tension spring 7 deforms and resets, driving the upper pressing arm 3 to rotate in the reverse direction, driving the upper movable pressing rod 4 to move towards the upper winding wheel 2 until the upper movable pressing rod 4 presses tightly on the fiber wound around the upper winding wheel 2, realizing the clamping and fixing of one end of the fiber to be measured. Finally, the same operation is repeated to complete the clamping and fixing of the other end of the fiber to be measured, and then the tensile testing machine can be used to perform the strength detection operation on the fiber to be measured.
