Through the arrangement of the protective shell 13, accidental touch of the button 10 can be prevented.

[0021] Refer to Figure 2, a light source activation mechanism 4 is provided inside the cavity 2.

When the light in the detection environment is weak, just lift the protective shell 13 to expose the button 10, and then press the button 10. The top pin 9 on the button 10 will push the locking pin 7 into the insertion block 5 and separate the locking pin 7 from the optical fiber signal identifier main body 1, thereby releasing the restriction on the insertion block 5.
