At this time, the photovoltaic panel is in contact with the sliding rod, and the photovoltaic panel is qualified. When the sliding rod pushes the first detection contact to contact the second detection contact on the second detection mechanism, the photovoltaic panel is unqualified. When the sliding rod moves upward a large distance, it pushes the second piston rod to move upward along the second detection cavity and compresses the third elastic component to prevent the sliding rod from moving upward a large distance and causing damage to the detection device.
