[0002] The bend test is a test method used to evaluate the bending performance of materials or products under stress. It is usually used to measure the flexibility, strength and durability of materials. The bend test can be applied to various materials, such as metal, plastic, rubber and paper. In order to save manpower and improve the efficiency of the bend test, the corresponding bend tester is often used to replace manual bend tests on different materials.

[0003] With the increasing demand for bending fatigue testing, products have expanded from conventional power cords, data cables, mobile phones and computers to accessories such as disposable lunch boxes, springs, toilets and trash can lids.

As a result, the applicability of the same bending test equipment to different products is relatively narrow and the application range is relatively limited, reducing the demand for multiple testing equipment and the subsequent heavy maintenance. Therefore, technical personnel in this field provide a multifunctional bending tester to solve the problems raised in the above background technology. Utility Model Content
