Problems solved by technology

[0003] When the crystal oscillator is measured, the pins of the crystal oscillator need to be in contact with the measuring device to form a circuit. When the crystal oscillator is loaded, it is generally done manually. After a crystal oscillator is measured, it needs to be removed and replaced with a new crystal oscillator. , it may be necessary to manually take the crystal oscillator body repeatedly for loading and unloading during measurement, the labor intensity of the staff is high, and the measurement efficiency may be low; when measuring the crystal oscillator components, the pins may be covered with dust, which may affect the crystal oscillator.
