[0024] Specifically, the optical fiber output end and the optical fiber receiving end of the detection head are respectively connected to the optical fiber bundle, and the other end of the detection head is connected to the optical fiber amplifier through the optical fiber bundle. The optical fiber amplifier emits visible light and transmits it through the optical fiber output end. The optical fiber receiving end is used to receive this visible light.

The lower bracket 12 is connected to the optical fiber receiving end through the second through hole 120. The second through hole 120 connects the upper surface and the lower surface of the lower bracket 12. The optical fiber receiving end extends into the second through hole 120 from the lower surface of the lower bracket 12. The first through hole 110 and the second through hole 120 are collinear so that the optical signal output from the optical fiber output end passes through the lower surface of the upper bracket 11, the paper opening 10 and the upper surface of the lower bracket 12 into the optical fiber receiving end.
