The flute tube assembly includes a core tube socket, an inner tube and an outer tube. A row of damping through holes is formed in each of two ends of the outer tube, a first check valve is arranged at one end of the outer tube and inserted into the piston rod, and the other end of the outer tube is arranged on the core tube socket and is connected to the nitrogen container through a first oil tube pipeline; the core tube socket is communicated with the first oil tube pipeline through a second check valve; the bottom end of the inner tube is fixed to the core tube socket and connected to the nitrogen container through a second oil tube pipeline.
