At this time, close the two installation rings 3, so that the connecting block 12 can enter the inside of the right installation ring 3, and then move the clamping block 10 downward, so that the clamping block 10 can penetrate through the connecting block 12 and be engaged with the inside of the clamping groove 11, so that the two installation rings 3 are stably connected. Then start the telescopic rod 13 to operate, so that the telescopic rod 13 can push the placing block 15 downward, so that the placing block 15 can push the supporting block 17 to fit with the asphalt tank, so that the body 1 can be supported by the supporting block 17, thereby reducing the vibration of the sampling device, making the connection between the sampling device and the asphalt tank not shake, so that the flow rate during the sampling process is relatively stable, so that the sample is relatively uniform, and thus the detection result will not be affected.

[0027] In order to ensure that the installation ring 3 does not shift after installation, a plurality of limiting grooves 5 are provided inside the installation groove 2. A limiting block 4 is inserted into the limiting groove 5. The limiting block 4 and the limiting groove 5 are used in cooperation to limit the position of the installation ring 3. The other end of the limiting block 4 is fixedly connected to the installation ring 3.

[0028] After the installation ring 3 is installed inside the installation groove 2, the limiting block 4 can enter the corresponding limiting groove 5, so that the limiting block 4 can limit the installation ring 3, and further prevent the installation ring 3 from shifting, thus making the installation of the installation ring 3 relatively stable.

[0029] In order to facilitate the movement of the clamping block 10, a placement groove 6 is provided inside the right installation ring 3. A pull rope 7 is slidably connected inside the placement groove 6. The placement groove 6 limits the pull rope 7, so that the pull rope 7 does not shift during movement.
