[0002] In production activities, it is necessary to test the functions of products before shipment, and there are many test items, often requiring multi-station testing. To improve production testing efficiency, most test line bodies are arranged in a pipeline manner. Most products have requirements for their appearance, and it is necessary to ensure that the products will not be damaged due to factors such as impact and friction during the testing process. Therefore, protective fixing fixtures need to be used. The fixing fixture can be customized in shape, has no high requirements for environments such as impact or friction, can facilitate the operation personnel to pick up and place, and improve the operation efficiency while improving the testing accuracy.

[0003] In the prior art, conventional jigs do not have a self-locking function after pressing and are very easy to be opened. During the testing process, if they are opened, it may cause board burning or scrapping, and the risk is very high. Currently, the general method is to paste warning signs or add an additional driving force separately for locking. This method requires manual operation, and there is a sequence for pushing in and withdrawing, the operation is complex, the risk of misoperation is high, and the efficiency is low, so it is very inconvenient to use. In view of this, we introduce a device with a self-locking function to prevent opening. Content of the Utility Model
