[0043] By adopting the above technical solution, the problem that the existing optical fiber temperature measuring device for mining cannot be used for cables of different diameters when in use and cannot be used normally when the diameter of the cable is greater than or less than the distance between the fixing seat and the fixed arc plate is solved.

[0044] Working principle: When in use, the first shell 1 and the second shell 2 are placed outside the cable. When the diameter of the cable is large, the cable contacts the rotating roller 1205, so that the arc plate 1202 drives the spring 1203 to contract and drives the limiting rod 4 to move. At this time, due to the elastic force of the spring 1203, the rotating roller 1205 clamps the cable. Then the user fixes the first extension plate 5 and the second extension plate 6 with the bolt 7. At this time, the first shell 1 and the second shell 2 are also fixed. Then the user can push the first shell 1 and the second shell 2 to move the device. When the first When the shell 1 and the second shell 2 move, the battery 1210 will also provide power for the motor 1301, and the motor 1301 will drive the gear 1302 to rotate, and the gear 1302 will engage with the tooth groove 1303, so that the rotating ring 1207 will rotate along the extension ring 1206.

Then the battery 1210 provides energy for the temperature measuring probe 1208, and the temperature detected by the temperature measuring probe 1208 will be displayed on the display screen 1209, so that the user can intuitively observe the temperature of the cable.
