The support rod 23 compresses the spring 24, and then the support rod 23 is released, so that the elastic force of the spring 24 drives the support rod 23 to position the cylindrical part 6, so as to better support the cylindrical part 6.

The support rods 23 compress the springs 24, and then the support rods 23 are released, so that the elastic force of the springs 24 drives the support rods 23 to position the cylindrical portion 6, so as to better support the cylindrical portion 6.

[0043] When testing, add the gasoline to be tested through the oil filling port 5, and then start the octane rating machine 2 for testing. When the filter layer inside the cylindrical part 6 needs to be replaced after a period of time, remove the cylindrical part 6 by loosening the mounting part 7, and then extend the clamp or other auxiliary tools into the exhaust part 8, clamp the outside of the fixing ring 11, and then rotate the clamp clockwise to drive the fixing ring 11 to rotate, so that the fixing ring 11 drives the mounting block 16 to rotate, and the mounting block 16 drives the magnetic block 17 to disengage from the magnetic block 2 18, so that the mounting block 16 is rotated out from the inside of the rotating groove 15 until the mounting block 16 is disengaged from the positioning block 10, and the fixing ring 11 can be removed, and then the filter layer in the fixing ring 11 can be replaced. Similarly, during installation, fix the fixing ring 11 with a clamp, rotate counterclockwise to keep the mounting block 16 stuck to the inside of the rotating groove 15, and the magnetic block 17 and the magnetic block 2 18 are adsorbed.
