Stirring mechanism suitable for lithium niobate crystal proton exchange furnace

The stirring mechanism suitable for the lithium niobate crystal proton exchange furnace provided by the utility model comprises a lifting module arranged on one side of the lithium niobate crystal proton exchange furnace; the upturning assembly comprises a base, a ratchet mechanism and a turnover body which are connected in sequence, the base is driven by the lifting module to enable the upturning assembly to move up and down relative to the lithium niobate crystal proton exchange furnace, and the turnover body can be turned over upwards relative to the base through the ratchet mechanism; and the rotating assembly is arranged at the end part of the turnover body, is connected with the quartz rod and is used for driving the quartz rod to rotate, a quartz flower basket is mounted at the bottom end of the quartz rod, and a lithium niobate substrate is mounted in the quartz flower basket. The stirring mechanism provided by the utility model solves the problems that stirring is insufficient and unstable in the pro
