求翻译：其原动力是依靠电动机通过蜗轮减速器带动偏心轮，再经连杆后，把圆周运动变为往复运动，带动腭板在一定范围来回摆动。是什么意思？

Its driving force is relying on driven motor via worm reducer eccentric wheel, and then upon connecting rods, and turn circular motion into reciprocating motion, driven palatal plate swinging back and forth in a certain range.

Its primary motivation is to rely on electric motors through worm wheel round eccentric reducer, driven by the connecting rod, after the campaign into reciprocating motion circumference cleft palate GEM, driven to a certain extent the swing back and forth.

Its driving force is depends upon the electric motor through the worm reducer impetus eccentric, after again passes through the connecting rod, becomes the circular motion the reciprocal motion, the impetus e board back and forth swings in certain scope.
