The function of the winding wheel 28 is to wind the polyester industrial yarn to fix its surface tension. The surface of the extrusion block 212 contacts the clamping block 27. The extrusion block 212 and the clamping block 27 move towards each other to clamp the polyester industrial yarn, solving the problem that traditional equipment can only clamp a single industrial yarn. Multiple groups can be clamped at the same time. The bottom end of the clamping block 27 is fixedly connected to the fixing block 26. The movement of the fixing block 26 will synchronously drive the clamping block 27 to move. The surface of the sliding block 29 is fixedly connected to the connecting plate 213.

With a protective cover 34, the fixing seat 33 synchronously drives the protective cover 34 to move up and down. The protective cover 34 can be lowered while clamping and fixing the polyester industrial yarn, which can effectively prevent accidental breakage during endurance side testing and prevent accidental injury caused by the splashing of polyester industrial yarn. The surface of the connecting seat 1 is provided with a sliding groove, and the protective cover 34 is slidably connected in the sliding groove of the connecting seat 1. The function of the sliding groove of the connecting seat 1 is to limit and guide the protective cover 34, so that the protective cover 34 can only slide along the direction of the sliding groove of the connecting seat 1.

[0022] Working principle: First, the industrial yarn is wound around the surface of the winding wheel 28 for initial fixation. Then, the motor 21 is started, and the output shaft of the motor 21 drives the threaded rod 23 to rotate. The upper and lower sets of sliding blocks 29 are connected to the sliding rod 25 through the connecting rod b24, and the upper and lower sets of fixed blocks 26 are connected to the sliding rod 25 through the connecting rod a22. When the threaded rod 23 rotates, the connecting rod b24 threaded to its surface slides on the surface of the threaded rod 23, synchronously driving the other set of sliding blocks 29 at the upper end to move. The sliding blocks 29 and the fixed blocks 26 move towards each other to initially clamp and fix the industrial yarn. The upper sliding seat 210 of the sliding block 29 is slidably connected to the squeezing block 212 through the spring 211 in the sliding groove of the sliding seat 210 and contacts the clamping block 27. With the winding wheel 28 on the outside of the fixed block 26 contacting the inside of the sliding block 29, it can adapt to polyester industrial yarns of different sizes. In the reciprocating motion, it completes the stable clamping of the polyester industrial yarn and repeated stretching, bending and other fatigue resistance tests.

[0023] At the same time, the connecting block 31 on the outside of the connecting rod b24 will move synchronously. The movement of the connecting block 31 will drive the hinge rod 32, which is hinged to it, to slide up and down. The hinge rod 32 will drive the protective cover 34 on the fixed seat 33 to slide up and down. This will prevent the fragments of the broken wire from causing injury to the staff during fatigue testing, effectively reducing the risk of safety accidents. At the same time, it can isolate external impurities, reduce the corrosion of external impurities on the components, extend the service life of the equipment, and prevent external airflow and foreign objects from interfering with the clamping and stretching state of the industrial wire, ensuring accurate and reliable test data.
