[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specified requirement. After the relay is produced, it needs to be tested for shock resistance.

[0003] An existing Chinese public patent (authorization announcement number: CN211696865U) mentions a testing device for automobile relay production, which can drive the testing platform to vibrate horizontally and reciprocatingly to detect the impact load that the automobile relay can withstand. A vibration motor is provided to drive the testing platform to vibrate to detect the automobile relay's ability to withstand vibration. The testing platform is arranged in a box, and an electric heating tube is provided in the box to detect the automobile relay's ability to withstand high temperatures and the comprehensive ability of the automobile relay to withstand the environment during use.

[0004] In the existing shock test of relays, most of the time, the electromechanical device is fixed on the test table through a fixing mechanism, so as to facilitate the test of the relay. However, in order to test the shock resistance of the relay, a large impact force is often applied. If the relay is of unqualified quality, it may scatter fragments on the test table after the impact. After the test is completed, the worker needs to reach into the box to clean the test table, which is inconvenient to operate and not convenient for the staff to use. Utility Model Content
