A circular hole 4 is provided at the top of the clamping groove 3 on the upper clamping block 2. An elastic spring 5 is installed at the top of the circular hole 4. A moving block 6 is installed at the lower end of the elastic spring 5. A temperature measuring head 7 is installed at the lower end of the moving block 6. The temperature measuring head 7 is on the elastic spring Under the support of 5, the temperature measuring head 7 has a certain elastic force, which can automatically contact the surface of the cable to facilitate temperature measurement. A fixing rod 8 is installed at one end of the lower clamping block 1, and a connecting rod 9 is installed on one side of the lower end of the upper clamping block 2. The lower end of the connecting rod 9 is slidably installed inside the fixed rod 8. A moving frame 10 is adjustably installed on the surface of the fixed rod 8, and a limiting block 11 is movably installed on the moving frame 10. The limiting block 11 is used to limit the connecting rod 9, so as to realize the fixing of the cable clamping by the lower clamping block 1 and the upper clamping block 2.

[0023] Specifically, the temperature measuring head 7 extends to the outside of the circular hole 4, a power supply component and a temperature measuring device are installed inside the upper clamping block 2, the temperature measuring device and the temperature measuring head 7 are electrically connected, a display screen 12 is installed at the front end of the upper clamping block 2, and a switch button 13 is provided at the front end of the upper clamping block 2 on one side of the display screen 12. The display screen 12 is used to display the data measured by the temperature measuring head 7, and the switch button 13 is used to control the switch state of the temperature measuring device.

[0024] Furthermore, the surfaces of the clamping grooves 3 at the front and rear parts of the temperature measuring head 7 are both installed with anti-skid layers 14, which are made of anti-skid rubber material.

[0025] Furthermore, a T-slot 15 is arranged on the upper end of the fixing rod 8, and elastic springs 16 are installed at the front and rear parts of the bottom of the T-slot 15. The connecting rod 9 is slidably installed inside the T-slot 15, and the lower end of the connecting rod 9 is jointly installed on the upper ends of the two elastic springs 16. When the connecting rod 9 moves downward, the elastic springs 16 are compressed, so that when the pressure on the upper clamping block 2 is released, the upper clamping block 2 returns to its original position, thereby playing a restoring role.

[0026] Furthermore, the movable frame 10 is sleeved on the surface of the fixed rod 8, and a movable groove 17 is arranged through the end of the movable frame 10 away from the lower clamping block 1, and the limit block 11 slides inside the movable groove 17, and an anti-slip pad 18 is installed at one end of the limit block 11 close to the connecting rod 9.

By using the fixing bolt 24, the position of the movable frame 10 can be adjusted, so that the user can adjust the pressing position of the limit block 11 according to the user's usage habits.

[0029] The method of using this embodiment is as follows: when using the optical fiber temperature measuring device that is convenient for clamping cables, press the switch button 13 to start the temperature measuring device, and then place the cable to be temperature measured inside the clamping groove 3 on the lower clamping block 1, and then drive the connecting rod 9 to move downward inside the T-slot 15 inside the fixed rod 8 by pulling the pull rod 23 or pressing the upper clamping block 2, and the connecting rod 9 drives the upper clamping block 2 to move downward, so that the upper clamping block 2 and the lower clamping block 1 clamp the cable, and at the same time the temperature measuring head 7 contacts the cable, and the temperature measuring head 7 compresses the elastic spring 5 through the moving block 6 to make the temperature measuring head 7 The head 7 maintains appropriate pressure and contacts with the cable surface, and then presses the limit block 11. The anti-slip pad 18 on the limit block 11 contacts with the connecting rod 9 to limit the connecting rod 9, so as to clamp and fix the cable by the lower clamping block 1 and the upper clamping block 2. The temperature measuring head 7 measures the temperature of the cable and displays the result on the display screen 12. Then the limit block 11 is released. Under the action of the elastic spring three 21, the anti-slip pad 18 does not contact with the connecting rod 9. At the same time, the elastic spring one 5 recovers and drives the upper clamping block 2 to return to its original position. Then the cable is taken out of the clamping groove 3, and the next temperature measurement can be carried out.
