[0026] By adopting the above solution, the polyester filament can be effectively wound around the clamping groove 12 by setting the clamping groove 12, and then clamped by the clamping block 504, which avoids the polyester filament from shifting or sliding during the clamping process and improves the stability and reliability of the clamping.

[0027] refer to Figure 4The second clamping device 7 includes a movable plate 701, a spring 702, and a locking block 703. The movable plate 701 is placed on the top of the housing 1.

[0034] By adopting the above solution, the stability and reliability of clamping can be improved by setting the slot 19, and the slippage or displacement of the sample during clamping can be avoided.

[0035] The working principle of this utility model:

[0036] In use, first use control panel 2 to start motor 502. Then motor 502 drives double-ended screw 503 to rotate. Double-ended screw 503 drives clamping block 504 to move along moving groove 18. Since the threads on both sides of double-ended screw 503 turn in opposite directions, the clamping blocks 504 on both sides move in opposite directions. Then, the polyester yarn is wound around clamping groove 12. Then, double-ended screw 503 is rotated in the opposite direction, driving clamping block 703 to clamp the polyester yarn. Then, press down on limiting plate 16, so that limiting plate 16 moves downward along stabilizing groove 15. Move the sliders 14 on both sides, and they will move forward and backward along with the limiting groove 17, thereby causing the two clamping blocks 703 to separate. At this time, place the other end of the polyester filament between the two clamping blocks 703, and then stop pressing the limiting plate 16. At this time, the reaction force of the spring 702 will cause the clamping block 703 to reset, thereby clamping the other end of the polyester filament. After the two ends of the polyester filament are clamped, start the motor 8 to drive the screw 9 to rotate. The screw 9 drives the moving plate 701 to move to the right along the slide groove 6, thereby pulling the polyester filament to perform tensile testing.

[0037] In summary, this testing device for high-strength polyester filament, through the coordinated use of a housing 1, control panel 2, support leg 3, force sensor 4, first clamping device 5, slide groove 6, second clamping device 7, motor 8, screw 9, protective shell 10, connecting block 11, clamping groove 12, receiving groove 13, slider 14, stabilizing groove 15, limiting plate 16, limiting groove 17, moving groove 18, and card slot 19, solves the shortcomings of existing polyester filament tensile strength testing devices in terms of clamping stability, uniform distribution of clamping force, and ease of operation. These devices cannot effectively prevent the polyester filament from sliding or shifting during clamping, and uneven distribution of clamping force may damage the polyester filament, affecting the accuracy and repeatability of test results.
