[0002] The main purpose of the tear resistance test of sofa fabrics is to evaluate the resistance of sofa fabrics to tearing by external forces, that is, the strength and stability of the fabric when subjected to tearing forces. This test usually involves a standardized tear test on the fabric to measure its ability to resist tearing. As an important part of furniture, the safety of the sofa fabric is of vital importance. Fabrics with good tear resistance are not easy to tear during use, thus avoiding accidental injuries caused by fabric damage, such as skin scratches, etc., and can better resist wear and tear in daily use, thereby extending the service life of the sofa.

[0003] For sofa manufacturers, tear resistance testing is an important means to evaluate the quality of sofa fabrics. Through this test, manufacturers can understand the performance characteristics of the fabrics and choose the most suitable products for production. At present, the tear resistance testing of sofa fabrics mostly relies on manual handheld dynamometers and other mechanical measuring instruments to monitor the pulling of sofa fabrics. The proportion of manual participation in the testing process is relatively large, and there are large testing errors, which affect the overall quality of the sofa fabrics. For this reason, the present application proposes a tear resistance testing device for sofa fabrics. Utility Model Content
