[0039] Working principle: During use, the user can adjust the four rubber blocks 20 according to the silencer body to be tested. By rotating the four second threaded rods 18, the four rubber blocks 20 can be moved and adjusted. At the same time, after the end of the silencer body 4 with the hole is fitted and connected to the four rubber blocks 20, the other end of the silencer body 4 can be placed on the upper end of the support column 10, so that the support column 10 supports the silencer body 4. Meanwhile, the user can rotate the rotating cylinder 13 set on one side of the fixed plate 9, which can be driven by the first threaded rod 6. The muffler body 4 is clamped and fixed by the connecting plate 14 with the sealing gasket 5. After the muffler body 4 is fixed, a suitable detection plate 15 can be embedded into the upper end of the adjusting frame 701 in the detection mechanism 7. By rotating the bidirectional screw 704 in the detection mechanism 7, the embedded detection plate 15 can be driven to fit against the outer surface of the muffler body 4. By moving the position of the detection plate 15, the degree of bending of the outer surface of the muffler body 4 can be detected. At the same time, the sound-generating device 2 is activated to detect the sound absorption effect of the muffler body 4 through the loudspeaker 21.
