The first glue body 100 includes a test section 110 and a clamping section 120. The two ends of the test section 110 are respectively provided with a clamping section 120. The width of the test section 110 is smaller than the width of the clamping section 120. A long groove 111 is provided on the test section 110. The second glue body is arranged in the long groove 111. The second glue body is adhesively connected to the first glue body 100, so as to facilitate performance testing of the combination after the two glues are cured.

[0043] Specifically, the first glue is solidified into a first glue body 100 through a mold. The first glue body 100 includes a test section 110 and two clamping sections 120. The two clamping sections 120 are respectively located at both ends of the test section 110. A long groove 111 is formed on the test section 110. After the first glue body 100 is solidified, the second glue can be injected into the long groove 111. After the second glue is solidified to form a second glue body, the first glue body 100 and the second glue body are bonded to form a glue performance test body. The operator clamps the two clamping sections 120 of the glue performance test body respectively through a stretching tool, and installs the glue performance test body on the stretching equipment, so as to test the performance of the two glues after bonding, thereby improving the convenience of detection.

[0044] Optionally, the distances between the two ends of the long slot 111 and the two clamping sections 120 are equal. The balanced structure helps to improve the overall strength of the glue performance test body and enhances the accuracy and reliability of the test results.

[0045] like Figure 1 As shown, along the direction from clamping section 120 to testing section 110, clamping section 120 is connected to testing section 110 via a transition section 121 with gradually decreasing width. Rounded corners 122 are provided on either side of transition section 121. This design effectively reduces stress concentration and ensures even distribution of applied force during testing.
