[0030] Specifically, the fixing component includes an installation ring 3, two arc-shaped clamping plates 4 and a threaded rod 5. One of the arc-shaped clamping plates 4 is fixedly welded to the inner side of the installation ring 3. The threaded rod 5 is rotatably connected to one side of the installation ring 3 away from one of the arc-shaped clamping plates 4, and one end of the threaded rod 5 passing through the installation ring 3 is connected to the other arc-shaped clamping plate 4 through a rotating part. Rubber layers 6 are provided on the opposite sides of the two arc-shaped clamping plates 4. A rotating handle 7 is fixedly welded to the end of the threaded rod 5 away from the other arc-shaped clamping plate 4. The rotating part includes a limit disk 8, and the limit disk 8 is fixedly welded to the end of the threaded rod 5 away from the rotating handle 7. A rotating groove 9 for the limit disk 8 to be rotatably connected is formed on the other arc-shaped clamping plate 4;

[0031] When fixing the sensor body 1, the sensor body 1 passes through the installation ring 3. One of the arc-shaped clamping plates 4 is in contact connection with the sensor body 1. Then, the threaded rod 5 is rotated through the rotating handle 7. Since the threaded rod 5 is rotatably connected to the installation ring 3, and the limit disk 8 at one end of the threaded rod 5 is rotatably connected in the rotating groove 9 inside the other arc-shaped clamping plate 4, the other arc-shaped clamping plate 4 can be driven to move and be in contact connection with the sensor body 1 to clamp and fix the sensor body 1;

[0032] The rubber layer 6 increases the clamping friction of the arc-shaped clamping plate 4 while reducing the friction on the sensor body 1.

[0033] The adjusting component includes a first connection block 10 and a second connection block 11. The first connection block 10 and the second connection block 11 are respectively fixedly connected to the installation ring 3 and the installation part. The second connection block 11 is rotatably connected in a connection groove 12 formed on the first connection block 10 through an adjusting bolt 21;

[0034] When the angle of the sensor body 1 needs to be adjusted, rotate the adjusting bolt 21, and then rotate the first connection block 10 to adjust the sensor body 1 to a suitable position, adjust and align it with the device to be detected. After adjusting to the suitable position, fix the adjusting bolt 21 to fix the first connection block 10 and the second connection block 11.

A connecting plate 19 is fixedly welded on the mounting plate 15, and a second mounting threaded hole 20 is opened on the connecting plate 19.

[0038] When winding the wire 2, wind the wire 2 around the winding column 17. When the wire 2 is wound to an appropriate length, then clamp one end of the wire 2 in the clamping groove 18. Since the fixing plate 16 is made of plastic and has toughness, the wire 2 can be clamped in the clamping groove 18 to fix the wire 2. Then use a bolt to connect with the second mounting threaded hole 20 to install and fix the wire winding mechanism, which can organize the wire 2 and avoid short circuit caused by the wire 2 being wound and knotted.

[0039] The working principle of this application is as follows:

[0040] Use a bolt to connect with the first mounting threaded hole 14 to install and fix the mounting plate 13. Then penetrate the sensor body 1 through the mounting ring 3. One of the arc-shaped clamping plates 4 is in contact connection with the sensor body 1. Then rotate the threaded rod 5 through the rotating handle 7, which can drive the other arc-shaped clamping plate 4 to move and be in contact connection with the sensor body 1 to clamp and fix the sensor body 1.

[0041] When it is necessary to adjust the angle of the sensor body 1, rotate the adjusting bolt 21, and then rotate the first connecting block 10 to adjust the sensor body 1 to an appropriate position and adjust and align the device to be detected.

[0042] Then fix the wire 2. Wind the wire 2 around the winding column 17. When the wire 2 is wound to an appropriate length, then clamp one end of the wire 2 in the clamping groove 18. Then use a bolt to connect with the second mounting threaded hole 20 to install and fix the wire winding mechanism.
