The tops of the first movable plate 10 and the second movable plate 11 are fixedly connected with a hollow frame 14, and the interior of the hollow frame 14 is rotatably connected with a number of evenly distributed rollers 15. The top of the left side plate 3 is hinged with a cover plate 16, and the center of the right side of the cover plate 16 is fixedly connected with a number of temperature sensing probes 17 corresponding to the clamping components 9. The front and rear sides of the right side of the right side plate 2 are fixedly connected with a clamping mechanism 18.

[0017] refer to Figure 4 The clamping mechanism 18 includes a support rod 19 fixedly connected to the right side of the right side plate 2, and the right end of the support rod 19 is hinged with a hook rod 20. The top of the hook rod 20 extends to the top of the right side plate 2, and the left side of the bottom of the hook rod 20 is fixedly connected to a compression spring 21. The left end of the compression spring 21 is fixedly connected to the right side of the right side plate 2, and the opposite side of the two hook rods 20 is fixedly connected with a cross bar 22.

[0018] In this embodiment, the support rod 19, the hook rod 20, the compression spring 21 and the cross rod 22 are installed in a corresponding manner. When the device needs to be closed, the cross rod 22 can be pressed to the left, driving the bottom of the hook rod 20 to move to the left, so that the top is away from the top of the right side plate 2, and then the cover 16 is closed so that it fits with the top of the right side plate 2.

[0022] In this embodiment, a retractable rubber cloth 26 is provided to protect the bottom of the optical fiber being tested, thereby preventing the surface of the optical fiber from rubbing against the internal parts of the device when adjusting the test position, which may cause damage to the optical fiber. By providing a rubber sleeve 27, the friction between the roller surface and the optical fiber surface is increased, thereby preventing the optical fiber from falling off from the inside of the clamping assembly 9 during testing, which may affect the detection accuracy.

[0023] refer to Figure 4 The four corners on the right side of the cover 16 are fixedly connected with connecting pieces 28 that are installed in pairs, and the opposite sides of the two connecting pieces 28 are hinged with dust removal brush plates 29 through a rotating shaft. The length of the brush end of the dust removal brush plate 29 is the same as the height of the hollow frame 14.

[0024] In this embodiment, the connecting piece 28 and the dust removal brush plate 29 are installed in a corresponding matching manner. When the detection position is adjusted, the cover plate 16 is closed to drive the brush end of the dust removal brush plate 29 to contact the surface of the optical fiber. The device moves to move the dust removal brush plate 29 on the surface of the optical fiber to clean the dust on its surface, thereby avoiding dust adhesion on the surface of the optical fiber and affecting the detection accuracy.

The surface of the T-shaped block 30 is slidably connected to the inner wall of the T-shaped slot 31.

[0026] This embodiment provides a corresponding matching installation setting of the T-shaped block 30 and the T-shaped slot 31, which plays a role of limiting and reinforcing the reverse screw block 12 and the positive screw block 13, so that they can only move left and right on the top of the base plate 1, and at the same time avoids the first movable plate 10 and the second movable plate 11 from shaking and getting stuck when following the reverse screw block 12 and the positive screw block 13, affecting normal use. The utility model passes each optical fiber that needs to be measured in temperature through the interior of the clamping assembly 9 so that it is located on the inner side of the hollow frame 14, and drives the first screw 5 to rotate forward by starting the forward and reverse motor 4. The forward rotation of the first screw 5 drives the second screw 6 to rotate forward through the belt 8 and the transmission wheel 7. When the first screw 5 and the second screw 6 rotate at the same time, the reverse screw block 12 and the positive screw block 13 approach each other, driving the hollow frame 14 approach each other, so that the surface of the roller 15 fits the surface of the optical fiber to fix the optical fiber, and then the top of the cover plate 16 is rotated to the right so that the right side fits the top of the left plate 3 and the right plate 2, and the cover plate 16 is fixed by the clamping mechanism 18 to close the device. The temperature sensing probe 17 is located above the optical fiber to detect the optical fiber. When the detection position needs to be adjusted, the roller 15 rotates due to contact with the optical fiber. It is only necessary to pull the device along the direction of the optical fiber to change the detection position, thereby achieving the convenience of adjusting the detection position of the optical fiber. Various positions of the optical fiber can be detected as needed, and it is convenient to detect optical fibers of different thicknesses.
