s2, rotating the turntable (405) to enable the turntable (405) to drive the threaded rod (402) to rotate, the threaded rod (402) can rotate at the arc-shaped block (403) through the sealing bearing (404), the tightness at the threaded rod (402) can thus be increased by the sealing bearing (404), meanwhile, the threaded rod (402) can drive the valve plate (302) to move through the valve rod (304), the valve rod (304) can drive the first connecting rod (506) to rotate through the first rectangular block (505), the first connecting rod (506) drives the second connecting rod (507) to rotate, the valve rod (304) can be limited by the first connecting rod (506) and the second connecting rod (507), when the valve rod (304) moves, the sleeve (503) above the valve rod (304) can also limit the valve rod (304), so that the valve rod (304) drives the valve plate (302) to always keep moving in the vertical direction.
