[0002] A portable optical power meter is an instrument used to measure the absolute optical power or the relative optical power loss through a section of optical fiber. In optical fiber systems, measuring optical power is the most basic, very much like a multimeter in electronics; in optical fiber measurement, an optical power meter is a heavy-duty commonly used meter.

[0003] Existing portable optical power meters, when performing optical fiber detection, realize the input of light source and perform detection through optical fiber connection. The optical power meter is often provided with a corresponding connector, which is generally protected by a threaded dust cap. However, there is generally no protective structure for the screen, and the protection effect of the screen is poor. For this reason, we propose a portable optical power meter. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model slides the H-shaped limit piece so that one end of the limit piece is inserted into the first limit seat, and squeezes the first spring so that the other end of the limit piece is disengaged from the shafts of the two sets of baffles, so that the baffle can be rotated to open and close the screen. When the screen is blocked, the elastic force of the first spring pushes the limit piece to be inserted into the shaft of the baffle, thereby locking the baffle and preventing the baffle from rotating.
