A kind of tea twisting machine structure (four),It includes: an ontology,One upper cover,One pushes part and an extrusion,The pushing part and extrusion system have each extended over limit guide plate,And it is respectively cooperating with the limit opening and limit passage port for the what ontology that stretches through,When pushing part and extrusion being made to be utilized respectively actuator drive displacement,Effectively can have linear slide state by limit opening and the limitation for limiting port,To increase the stability for pushing part and extrusion displacement,It is generated to prevent being laid particular stress on when stop bit shifting by unilateral situation,The limit guide plate system of the pushing part and extrusion is convexly equipped with guide wheel again,It is the pushing surface conflict sliding of recycling guide wheel and accommodating space inner wall or extrusion,Have both the smooth degree person for pushing part and extrusion displacement actuation.一種茶葉揉捻機結構(四)，其包含：一本體、一上蓋、一推擠件以及一擠壓件，該推擠件及擠壓件係分別延伸有限位導板，並分別配合穿伸於本體之限位開口及限位通口處，使推擠件及擠壓件分別利用驅動件帶動位移時，可有效藉由限位開口及限位通口的限制具線性滑動狀態，以增添推擠件及擠壓件位移之穩定性，以防止位移時偏重依靠單邊之情況產生，又該推擠件及擠壓件之限位導板係均凸設有導輪，係可再利用導輪與容置空間內壁或是擠壓件之推擠表面抵觸滑移，兼具推擠件及擠壓件位移作動之順暢度者。
