[0002] Footwear is an indispensable necessity in daily life, and buckles are used in many shoe models. Buckles can not only adjust the tightness of shoes to suit different foot shapes and wearing needs, but their diverse shapes and designs also add beauty to the appearance of shoes.

[0003] However, since the durability of the buckle is affected by many factors such as material selection, manufacturing process and usage environment, the buckle is very likely to be damaged due to the cumulative effect of fatigue under long-term and high-frequency use, which manifests as increased wear and structural fractures, which not only reduces the service life of the shoes, but also affects the consumers' wearing experience. Moreover, in footwear products such as high heels, the sudden breakage of the buckle may cause the wearer to lose balance or even fall, causing physical injury. Therefore, it is necessary to conduct anti-fatigue tests on the functional buckles of finished shoes to evaluate their performance under long-term use conditions, so as to predict their durability, reduce the adverse consequences caused by buckle damage, and enable consumers to have a better wearing experience.

Acquire the test times of the sample 16 in the motion state in real time, and determine whether the preset test times are reached. When the test times reach the preset test times or the sample 16 breaks, stop the motion and the test ends.

[0046] In a specific embodiment, two groups of samples to be tested are prepared, and the actual lengths 16 of the samples to be tested are preprocessed according to the position distance of the clamping mechanism 2 .
