As the limit block 23 shrinks, the dustproof plate 25 can be removed from the inner side of the fixed frame 19.

[0055] S4. By utilizing the elastic structure between the push plate 27 and the main body 1 of the primary frequency modulation test device, when the dial plate 24 is pulled to cause the connecting plate 22 to drive the limit block 23 to contract, the push plate 27 will push the dustproof plate 25 under the action of the third spring 26, making it easier to take the dustproof plate 25 out of the fixing frame 19.
