Multiple vertical rods 10 are evenly fixedly connected to the lower surface of the moving plate 5. A sleeve plate 11 is sleeved below the outer wall of the vertical rod 10. The inner wall of the sleeve plate 11 has a clearance fit with the outer wall of the vertical rod 10. Tensile testers 13 are arranged on both sides of the lower surface of the sleeve plate 11. One end of the tensile tester 13 is provided with a laser rangefinder. The wiring terminals of the laser rangefinder and the tensile tester 13 are both electrically connected to two of the wiring terminals of the controller 4 through wires.

At this time, the motor inside the machine box 7 can be powered on to make the lead screw 6 rotate. Due to the threaded connection relationship between the lead screw 6 and the moving plate 5, and the sliding limit of the slider 8 by the chute 9, the moving plate 5, the vertical rod 10, the sleeve plate 11 and the convex rod 14 can move upward at a uniform speed to stretch the installed spandex yarns 15. During this period, the acting force between the sleeve plate 11 and the tensile tester 13 gradually increases.

In this process, the motor inside the machine box 7 can perform tensile tests on multiple spandex yarns 15 simultaneously with a single operation, which can reduce the energy consumption required for the operation of the device and is also conducive to the efficient test operation of the enterprise. The tensile force measuring device 8 and the laser rangefinder synchronously display the tensile force value and the length change amount at the moment when multiple spandex yarns 15 break on the display board of the controller 4, which is convenient for the operator to record the test data, take the average value and the median value to obtain accurate elastic force values.
