Optical power tester

The utility model provides an optical power tester comprising a lower housing, the lower housing is movably contacted with an upper housing, and one side of the lower housing is provided with a charging interface. The L-shaped rod is pulled to drive the moving rod to slide on the round rod so as to stretch the first spring, the L-shaped rod is moved upwards to drive the baffle to move upwards through the moving rod and the round rod so as to compress the second spring, the L-shaped rod is aligned with the clamping groove through observation, force on the L-shaped rod is released, the first spring in the stretched state is reset, and the second spring is compressed. A first spring drives an L-shaped rod to be clamped with a clamping groove through a moving rod, a charging interface is exposed for charging, after charging, the L-shaped rod is pulled to be separated from the clamping groove, a second spring in a compressed state is reset, the second spring drives a baffle to shield the charging interface, and du
