Vibration transmission integrated coaxial quartz enhanced photoacoustic spectrometry gas detection device and system

The invention discloses a vibration transmission integrated quartz enhanced photoacoustic spectrometry gas detection device. A lead-in resonant tube and a lead-out resonant tube which are coaxially arranged are arranged around a quartz tuning fork of the vibration transmission integrated quartz enhanced photoacoustic spectrometry gas detection device; the lead-in resonant tube and the lead-out resonant tube are in resonant coupling with the quartz tuning fork; frequency-modulated gas molecules absorb wave band incident light and sequentially pass through the introduction resonance tube, the introduction and extraction vibration arm gap of the quartz tuning fork and the extraction resonance tube; the introduction resonance tube is a strip-shaped optical waveguide and is provided with an inner cavity extending in the axial direction, an opening in the tail end of the introduction resonance tube is located near the quartz tuning fork introduction vibration arm, and the tail end of the introduction resonance tube
