    • A grass trimmer includes a housing having a lower base wall from which extends a hub member of a predetermined height coupled to a motor encased in the housing, which motor drives the hub member rotatably. A cutting line element is attached to the hub member. A rim extends outwardly from the housing about the perimeter of the base wall. A first rim portion is of a height greater than the hub member and includes first and second spaced mounting ears extending therefrom toward the hub member. A protective shield designed for mounting on the housing in spaced relation from the base wall, is planar and of a similar shape to the base wall. The shield includes first and second tab and shoulder assemblies located for cooperation with the ears on the rim portion of the housing. Joining the last mentioned assemblies and respective ears attaches the shield to the trimmer housing. A resilient locking lever arm provided on the shield cooperates with a locking rib formed on the rim portion of the housing upon engagement of the tab and shoulder assemblies and mounting ears to removably lock the shield to the housing. The shield prevents the hub member from being driven into the grass during operation of the trimmer, thereby preventing damage to the motor driving the hub member.An aperture in the protective shield permits easy attachment of cutting line elements to the hub member without removing the shield.
    • 草地修剪器包括具有下底座的壳体,从该底座壁延伸出预定高度的轮毂构件,该轮毂构件与装在壳体中的马达相连接,该马达可旋转地驱动轮毂构件。 切割线元件附接到轮毂构件。 轮缘围绕基座的周边从外壳向外延伸。 第一边缘部分的高度大于轮毂部件,并且包括从其向着毂部件延伸的第一和第二隔开的安装耳。 设计用于以与基座隔开的关系安装在壳体上的保护屏蔽是平面的并且具有与底壁相似的形状。 护罩包括第一和第二突片和肩部组件,其位于用于与壳体的轮缘部分上的耳朵配合。 加入最后提到的组件和各自的耳朵将护罩固定在修剪器外壳上。 设置在屏蔽件上的弹性锁定杆臂与突出部和肩部组件和安装耳接合时形成在壳体的边缘部分上的锁定肋配合,以将屏蔽件可拆卸地锁定到外壳。 屏蔽件防止在修剪器操作期间轮毂件被驱动到草地上,从而防止损坏驱动轮毂件的马达。 防护罩中的孔径允许将切割线元件容易地附接到轮毂构件而不移除护罩。
