the flower-shaped teeth on the flower-shaped roller 82 extrude the arc-shaped plate 832, the flower-shaped roller 82 continues to rotate, the flower-shaped teeth on the flower-shaped roller 82 also start to deflect to one end of the arc-shaped plate 832, and then the arc-shaped plate 832 starts to extrude a spring between one end of the arc-shaped rod 834 and the bottom of the arc-shaped sleeve 833, so that the better damping effect is achieved when the arc-shaped plate 832 is meshed with the flower-shaped teeth on the flower-shaped roller 82; meanwhile, the arc-shaped plates 832 drive the adjacent arc-shaped plates 832 to swing through the arc-shaped sleeves 833 and the arc-shaped rods 834, so that the next meshed corrugated bulge of the flower-shaped roller 82 can enter the arc-shaped plates 832 more easily, and the transmission between the flower-shaped roller 82 and the second roller 83 is smoother; second embodiment of roller number two: the flower-shaped teeth on the flower-shaped roller 82 are meshed with the arc-shaped teeth on the arc-shaped tooth roller 835, the flower-shaped teeth on the flower-shaped roller 82 extrude the arc-shaped baffle 836, and the arc-shaped baffle 836 compresses the spring, so that the better damping effect is achieved when the arc-shaped tooth roller 835 is meshed with the flower-shaped teeth on the flower-shaped roller 82; the impact of the liquid in the pipeline on the sleeve 1 is firstly damped by the damping module 5, then the lateral impact is absorbed by the telescopic rod 70, and finally the impact transmitted by the vibration cylinder 4 is absorbed by the damping module 8, so that the thermocouple 2 can test the temperature under the condition of no impact and vibration, and the accuracy of the test result is improved.
