AI Technical Summary
The lack of reliable fixtures in the existing technology for testing the tensile properties of adhesives, especially the 180° peel strength and slip resistance, leads to unstable test results.
A clamping structure including a clamping base, clamping plate, main screw, auxiliary screw and spring is designed. Through the threaded engagement and spring design, the clamping plate is ensured to maintain parallel movement during clamping, providing a stable clamping force, which is suitable for testing the tensile properties of adhesives.
It achieves reliable clamping of adhesive test samples, ensuring the stability and reliability of test results. The structure is simple, lightweight, and easy to operate.
