[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A fluorescent fiber optic temperature measuring device;

[0024] The device includes a mounting plate 1, a support frame 3, a temperature measuring device body 15, and an adapter fiber optic cable 17. Two sets of support rods 4 are installed on the outer side of the support frame 3, and these rods 4 movably pass through the interior of the two mounting plates 1.

One end of the two sets of second positioning rods 11 is connected to a connecting rod 13, and the connecting rod 13 is arc-shaped. The front of the connecting rod 13 is provided with a toggle plate 14, and the toggle plate 14 is located below the temperature measuring device body 15.

[0025] Both sets of mounting plates 1 are L-shaped plates. The No. 1 through groove 2 inside the mounting plate 1 can be used to position the two sets of mounting plates 1 on the inner wall of the cabinet. The support frame 3 is rotatably set between the two sets of mounting plates 1 using two sets of support rods 4 on the outside. One end of the support rod 4 is provided with a mounting plate 5.
