[0013] Compared with related technologies, the flame retardancy testing device for high-performance fiber flame retardant yarn provided by the present invention has the following beneficial effects:

[0014] 1. By precisely adjusting the distance between the two adjustment platforms, yarns of different lengths can be properly placed between the two support plates, improving the flexibility and adaptability of the test. At the same time, the combination of the limit block and the pressure plate firmly presses and fixes the two ends of the yarn, preventing the yarn from sliding or loosening during the test and ensuring the accuracy of the test.

[0015] 2. Tightening the pressure block applies pressure to the pressure plate, effectively limiting its upward and downward rotation, thereby improving the clamping effect of the limit block on the yarn. This design not only enhances the stability of the yarn during testing, but also maintains a stable posture and position, avoiding test errors caused by yarn shaking or deformation. By adjusting the position between the two adjustment platforms, the yarn can be tightened to ensure that the yarn is at the appropriate tension during testing. At the same time, tightening the locking bolt limits the movement of the adjustment platform, making it less likely for the yarn to tilt or deflect during flame combustion, thereby improving the safety and reliability of the test.

[0016] 3. The debris dropped by burning will fall into the filter directly below. Since the square groove and the connecting frame are snap-fitted, it is convenient to install and disassemble the connecting frame, and the debris dropped by burning on the filter can be easily collected, making subsequent cleaning more convenient.
