[0034] The implementation principle of the embodiment of the present invention is as follows: when testing a conventional filter, the filter is installed between the two clamping plates 3.

After the filter is fixed, the output line 9 and the input line 10 are installed on the sliding table 14 according to the positions of the input and output ends of the filter, and the height and position of the output line 9 and the input line 10 are adjusted. At the same time, the nut 13 is driven to abut against one end of the mounting plate 4 toward the clamping plate 3.

When the filter is installed, the nut 13 cannot abut against the mounting plate 4 or the filter cannot be installed on the mounting table 2. If there is a size difference between the filter and the previous filter, it is necessary to readjust the output line 9 and the input line 10 according to the actual situation. After the output line 9, the input line 10 and the nut 13 are adjusted, the sliding table 14 is controlled. The moving platform 14 is formed, and the sliding platform 14 is driven to slide, so that the input line 10 and the output line 9 are both inserted into the filter, the sound wave generator 7 is turned on and the sound wave frequency of the sound wave generator 7 is adjusted, so that the sound wave enters the filter for filtration and is sent to the sound wave detector 8 for detection, and the detected report is sent to the analysis equipment for analysis to determine whether the filter is qualified, and the filter detection is completed; when detecting the SAW filter, the position of the conduction box 221 and the conduction block 222 is adjusted according to the input and output ends of the SAW filter, and the output line 9 and the input line 10 are inserted into the corresponding plug interface 24, and then the SAW filter is installed between the two clamping plates 3 and the nut 13 is driven to abut against the mounting plate 4, by turning on the sound wave generator 7 and adjusting the sound wave frequency of the sound wave generator 7, the sound wave enters the SAW filter for filtration and is sent to the sound wave detector 8 for detection, and the detected report is sent to the analysis equipment for analysis to determine whether the SAW filter is qualified, and the SAW filter detection is completed.
