如图1所示，本实施例提供一种调节组件，调节组件包括驱动件1、传动机构2、电机壳3和底座4。其中：
底座4具有容纳腔41和导柱42，导柱42设置在容纳腔41内；电机壳3上设有筋板31和孔套32，孔套32位于筋板31的旁侧，电机壳3容置于容纳腔41内，并且，孔套32与导柱42滑动配合；传动机构2包括传动杆21，传动杆21上端与驱动件1配合,传动杆21下端与电机壳3的筋板31配合；传动杆21能够在所述驱动件1的驱动作用下，带动电机壳3相对于底座4上下移动。
传动杆21的表面设置有外螺纹，筋板31上设置有与传动杆21上的外螺纹相互配合的内螺纹，当传动杆21受到来自驱动件1的作用力时，传动杆21上的外螺纹与筋板31上的内螺纹相互配合，带动设有筋板31的电机壳3上下移动。
传动机构2还包括主动轮22、从动轮23和调档盖24，主动轮22上设有中 空的第一凸台221，调档盖24具有第二凸台241，主动轮22装配在调档盖24上，调档盖24的第二凸台241进入主动轮22上的第一凸台221，从动轮23与主动轮22啮合，从动轮23与传动杆21的上端相连，当主动轮22受到外力作用转动时，会带动从动轮23一起转动，同时从动轮23与传动杆21的上端相连，所以进一步传动杆21也会进行转动，需要指出的是，从动轮23可以焊接在传动杆21的上端，从动轮23和传动杆21也可以一体成型。
驱动件1包括底座盖11和旋钮12，底座盖11上设有通孔111，旋钮12设置在通孔111中。
第一凸台221的外侧设有卡接块2211，第一凸台221进入底座盖11上的通孔111，并通过卡接块2211与旋钮12卡接，在转动旋钮12的时候，与旋钮12卡接的第一凸台221会发生转动，同时因为第一凸台221设置在主动轮22，所以主动轮22也会一起发生转动。
孔套32套设在导柱42上并可沿导柱42的长轴移动，当转动旋钮12的同时，与旋钮12卡接的卡接块2211带动主动轮22转动，同时，与主动轮22啮合的从动轮23一起转动，从动轮23的转动会带动传动杆21一起转动，此时传动杆21上的外螺纹与筋板31上的内螺纹相互配合转动，带动电机壳3向上运动，进一步设置在电机壳3并套设在导柱42上的孔套32会沿导柱42的长轴移动。
导柱42的数量和孔套32的数量均为两个，筋板31位于两个孔套32之间，两个导柱42与两个孔套32一一对应设置，当转动旋钮12的同时，与旋钮12卡接的卡接块2211带动主动轮22转动，同时，与主动轮22啮合的从动轮23一起转动，从动轮23的转动会带动传动杆21一起转动，此时传动杆21上的外螺纹与筋板31上的内螺纹相互配合转动，带动电机壳3向上运动，在向上运动过程中，电机壳3会发生偏移，此时设置在筋板31两侧的孔套32会平衡掉作用力，通过在导柱42上沿长轴移动，保证电机左右平衡，避免卡死。
容纳腔41的内壁与电机壳3外壁之间的距离不小于传动杆21的直径，当转动旋钮12的同时，与旋钮12卡接的卡接块2211带动主动轮22转动，同时，与主动轮22啮合的从动轮23一起转动，从动轮23的转动会带动传动杆21一 起转动，所以设置在容纳腔41的内壁与电机壳3外壁之间的传动杆21的直径需不大于容纳腔41的内壁与电机壳3外壁之间的的距离。
容纳腔41与筋板31相对一侧的内壁为光滑曲面，并且与传动杆21之间存在间隙，或者，在另一种优选的方案中，容纳腔41与筋板31相对一侧的内壁设置有与传动杆21上的外螺纹相互配合的内螺纹。
底座盖11装配在底座4上，并通过螺钉固定。
本发明提供的一种调节组件，底座4具有容纳腔41和导柱42，导柱42设置在容纳腔41内；电机壳3上设有筋板31和孔套32，孔套32位于筋板31的旁侧，电机壳3容置于容纳腔41内，并且，孔套32与所述导柱42滑动配合；从而减少零部件数量，具有装配简单，操作便捷的优势，同时保证电机左右平衡，避免卡死。
本发明还提供一种割草机的切割装置，该割草机的切割装置除了包括以上提供的调节组件，还包括刀盘6和电机5。电机5安装在电机壳3内，电机5的输出轴51与刀盘6连接。
本发明最后还提供一种割草机，该割草机包括以上提供的割草机的切割装置。通过调节组件可以调整电机壳体相对于底座的高度，在电机壳体内安装电机并且电机连接刀盘的情况下，通过控制驱动件可以使刀盘向上或者向下移动，从而调整刀盘相对于地面的高度，以适应不同的除草环境。
调节组件的具体工作过程包括：
转动旋钮12的同时，与旋钮12卡接的卡接块2211带动主动轮22转动，同时，与主动轮22啮合的从动轮23一起转动，从动轮23的转动会带动传动杆21一起转动，此时传动杆21上的外螺纹与筋板31上的内螺纹相互配合转动，带动电机壳3向上运动，电机壳3内的电机5也一起向上运动，电机5上的输出轴51上升，带动刀盘6调高，最终实现割草机的刀盘6调高。
反向转动旋钮12的同时，与旋钮12卡接的卡接块2211带动主动轮22反向转动，同时，与主动轮22啮合的从动轮23一起反向转动，从动轮23的反向转动会带动传动杆21一起反向转动，此时传动杆21上的外螺纹与筋板31上的内螺纹相互配合反向转动，带动电机壳3向下运动，电机壳3内的电机5也一 起向下运动，电机5上的输出轴51下降，带动刀盘6调低，最终实现割草机的刀盘6调低。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
