[0002] Elastic fibers are widely used in base fabrics, socks, pantyhose, swimsuits, sportswear, tights and other clothing materials, as well as diapers, bandages, stents, masks, automotive interior decoration materials, nets, tapes and other non-clothing materials. The important property of fibers with long tensile properties is their elasticity. The size of elasticity and the recovery state of elasticity affect the use effect of fibers in textiles. Elasticity test is an important physical indicator for testing the performance of elastic fibers, but it still has the following disadvantages in actual use:
[0003] After the elastic fiber is manufactured, it needs to be tested for elasticity. During the test, basically, a suitable length is selected, and then after the bottom of the fiber is clamped at a suitable position, a weight of corresponding mass is hung, and the fiber length is measured to determine the fiber elasticity. However, during the test, it is necessary to carefully determine the corresponding fiber length, cut the fiber, and then clamp it, which is easy to cause detection errors;
[0004] After the elasticity test of the elastic fiber, during the working process, there is only a simple function of measuring the elasticity of the corresponding elastic fiber. However, when the elastic fiber is tested, there is also a step of testing the tensile force required to break it. The elasticity testing device is not compatible with this function.

When the support rods are working, the length of the detected fiber is measured by cooperating with the card frame through the measuring scale.
[0009] Furthermore, n equally spaced connecting rings are fixed on the side of the top of the top support bar away from the movable rod, and n≥2. n wiring holes are opened through the side of the top of the top support bar away from the connecting ring, and the wiring holes correspond to the positions of the connecting rings one by one. The top support bar restricts the connecting ring on the top support ring by tying the top end of the fiber to be detected to the connecting ring.
[0010] Furthermore, a blackened back plate is fixed to the top of the connecting cross bar, and the two sides of the blackened back plate are respectively fixed to two support rods, and the top of the blackened back plate is fixed to the bottom of the top support bar. When the connecting cross bar is working, the blackened back plate highlights the stretching condition of the corresponding elastic fiber being tested.
[0011] Furthermore, a movable hole is formed through the top of the connecting cross bar corresponding to the position of the wiring hole, the movable rod is movably connected in the movable hole, and the connecting cross bar is movably connected to the movable rod through the movable hole.
[0012] Furthermore, a winding ring is fixed to the lower part of the iron clamp away from the blackened back plate, a limiting disk is fixed to the bottom end of the movable rod, and a hanging ring is fixed to the bottom end surface of the limiting disk. When the iron clamp is working, the bottom end of the elastic fiber is tied through the winding ring, and the weight for pulling the elastic fiber is hung through the hanging ring.
[0013] The utility model has the following beneficial effects:
[0014] The utility model solves the problem of inconvenience in determining the fiber test length of an elastic fiber elastic testing device by arranging a bottom plate, a top support bar, a connecting cross bar and a movable rod. The fiber to be tested is selected, and one end of the limit is wound around the connecting ring at the top of the top support bar and fastened on the connecting ring. Subsequently, the fiber is passed through the wiring hole on the top support bar, and then the iron clamp is pulled until the top of the limiting disk contacts the bottom of the connecting cross bar, and the fiber is guided to the iron clamp at the top of the movable rod. The iron clamp is opened, the fiber is guided into the iron clamp, and the iron clamp is closed. Therefore, the length of the corresponding elastic fiber to be tested can be accurately limited, and the detection is more convenient.
[0015] The utility model solves the problem that the elasticity testing device of the elastic fiber does not have the function of detecting the tension required to break the elastic fiber by arranging a connecting horizontal bar and a movable rod. After the corresponding elastic fiber is restricted, a weight of a corresponding weight is hung on the hanging ring, and the corresponding fiber is pulled under the action of the weight. After repeating the above-mentioned measuring steps, the length of the elastic fiber stretched under the corresponding tension is determined, the elasticity of the elastic fiber is detected, and the weight is continuously added until the elastic fiber is broken, and the tension required to break the elastic fiber is determined. Therefore, the utility model can detect the tension required to break the elastic fiber, and has more diverse functions. BRIEF DESCRIPTION OF THE DRAWINGS
