[0002] Currently, functional testing of electronic products usually needs to use a flip cover type test fixture. The electronic product is placed on the fixture, then the flip cover is closed to press and fix the electronic product, and finally the product is tested. However, the existing flip cover type test fixture lacks a flip cover in place detection function, that is, it cannot detect whether the flip cover is completely closed in place, and lacks a fool-proof design to prevent the flip cover from not being closed in place and affecting the product positioning effect, thereby affecting the normal function of the fixture.

[0003] A patent document with the publication number CN217879439U discloses a flip cover type test fixture, which includes a base provided with a containing groove, a workpiece to be detected is placed in the containing groove, and an upper cover is closed on the base so that a pressing block assembly is located directly above the containing groove. The workpiece is pressed and fixed in the containing groove by the pressing block assembly to avoid shaking of the workpiece and ensure testing accuracy. However, after the upper cover is closed on the base and the pressing block assembly presses the workpiece, it cannot be accurately judged whether the upper cover is closed in place and whether the pressing block assembly is pressed in place, and thus it cannot detect whether the workpiece is completely positioned.
