Pin 432 is lowered and connected to the relay in the test fixture board 440, thereby performing a burn-in test on the relay;

The driving device 200 drives the transmission chain 300 to rotate. Since the material transfer test frame 410 is provided with a rotating shaft 412, the rotating shaft 412 is provided with a connecting rod 413, and the connecting rod 413 is hinged on the transmission chain 300, so that the transmission chain 300 can drive the rotation The material test frame 410 moves, and since the rotating shaft 412 is provided with a roller 414, the roller 414 rolls and is accommodated in the guide rail groove 112, so that the moving material test frame 410 can move along the guide rail groove 112 under the action of the roller 414. circular movement;
