[0002] A quartz crystal oscillator, referred to as a crystal oscillator for short, is made based on the principle that when the frequency of an electrical signal is equal to the natural frequency of a quartz crystal wafer, the quartz crystal wafer will generate a resonance phenomenon. According to this characteristic, it is often used in an LC oscillation circuit or a filter. At the same time, because the crystal oscillator has the characteristics of small volume and high stability, the requirements for the manufacturing process of the crystal oscillator are very high. Therefore, after the crystal oscillator is manufactured, it is necessary to perform a frequency test on the crystal oscillator assembly to ensure that the performance of the crystal oscillator can meet the requirements.

[0003] The existing crystal oscillator frequency testing devices usually need to detect the frequency of the crystal oscillator through a probe. During the test, it is necessary to first fix the crystal oscillator and then detect the frequency of the crystal oscillator.
