Membrane detector

The utility model relates to the technical field of diaphragm detection, and discloses a diaphragm detector, the top of a shell is provided with a detection hole, a detection plate is arranged in the shell and located at the bottom of the detection hole, the bottom of the detection plate is fixedly provided with a first pull rod penetrating to one side of the shell, the bottom of the detection plate is provided with a guide block, and the guide block is provided with a second pull rod penetrating to one side of the shell. When the diaphragm detector is used, the detection hole is matched with the detection head for penetrating detection, the detection plate is used for placing a diaphragm to be detected, after the diaphragm detector detects the diaphragm, when the detected diaphragm is qualified, the diaphragm is collected in the first collection frame, and when the detected diaphragm is unqualified, the diaphragm is collected in the second collection frame. The diaphragm detection device has the advantages t
