The surface of the fixing bolt 204 is slidably connected to the inner wall of the limiting plate 207.

[0029] Specifically, such as Figure 4 As shown, a fixing plate 208 is bolted to the bottom of the fixing bolt 204, the top of the fixing plate 208 contacts the bottom of the limiting plate 207, and a test plate 209 is fixedly connected to the bottom of the fixing plate 208.

[0030] In this embodiment: the first electric telescopic rod 201 connects and adjusts the connecting rod 202; the connecting rod 202 connects to the connecting plate 203; the connecting plate 203 connects the telescopic member 205 to the pressure sensor 206; the fixing bolt 204 bolts the fixing plate 208; and the telescopic member 205 connects to the limiting plate 207.

With the setting of the limiting plate 207, the limiting plate 207 can limit the fixing plate 208. With the setting of the fixing plate 208, the fixing plate 208 can connect and fix the test plate 209. With the setting of the test plate 209, the test plate 209 is an existing probe plate used for testing the connection end of the cavity filter, and its bottom is equipped with a distance sensor, which can detect the insertion distance of the probe.

[0031] Specifically, such as Figure 5 As shown, the test box 3 is fixedly connected to the two sides of the second electric telescopic rod 5, the inner side of the second electric telescopic rod 5 is fixedly connected to the connecting block 6, and the inner side of the connecting block 6 is fixedly connected to the protective pad 7.

[0032] Specifically, such as Figure 5 As shown, a slot 8 is provided at the bottom of the test chamber 3, and a scale 9 is fixedly connected to the inner wall of the slot 8.

[0033] In this embodiment: the second electric telescopic rod 5 can be used to connect and adjust the connecting block 6. The connecting block 6, in conjunction with the protective pad 7, can clamp and fix both sides of the cavity filter. In conjunction with the clamping plate 101, the cavity filter can be fixed in the middle of the bottom of the test chamber 3, thereby ensuring accurate testing.

[0037] Working principle: First, place the cavity filter to be tested at the bottom of the test chamber 3. Then, turn on the motor 104, causing the motor 104 to rotate the adjusting rod 103. This causes the adjusting rod 103 to adjust the adjusting plate 102, which in turn causes the adjusting plate 102 to adjust the clamping plate 101. This clamping plate 101 then clamps and fixes the front and rear sides of the cavity filter. Next, open the second electric telescopic rod 5 to adjust the connecting block 6. This allows the connecting block 6, in conjunction with the protective pad 7, to clamp and fix both sides of the cavity filter. During the fixing process, adjust the cavity filter left and right using the scale 9 to adjust the position of the cavity filter. The test plate 209 is attached to the bottom of the test chamber 3 at the center. Then, the first electric telescopic rod 201 is opened to adjust the test plate 209, allowing the probe at the bottom of the test plate 209 to be inserted into the connection end of the cavity filter. During the insertion process, the resistance is transmitted to the pressure sensor 206, and the data is transmitted to the control panel 4. The misalignment of the cavity filter connection end can be determined based on the magnitude of the force, and the insertion depth can be detected by the position sensor, providing further detection data. After testing the connection end of the cavity filter, the cavity filter can be removed for quick replacement and testing.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
