    • A lawn mower has a power source for rotationally driving an output shaft. A housing has an interior space having a generally spiral-shaped portion. A cutting blade is disposed in the interior space of the housing and is connected to the output shaft for rotation therewith to cut grass while the spiral-shaped portion of the interior space generates a swirling airflow allowing the cut grass to swirl within the interior space. An enclosure is connected to the housing and has a grass discharge passage having an inlet opening disposed in communication with the interior space of the housing for discharging grass cut by the cutting blade and swirling within the interior space of the housing. A guiding member is disposed in the interior space of the housing for gradually changing a direction of the swirling airflow and the swirling cut grass and for guiding the swirling airflow and the swirling cut grass toward the grass discharge passage of the enclosure.
    • 割草机具有用于旋转地驱动输出轴的动力源。 壳体具有大致螺旋形的部分的内部空间。 切割刀片设置在壳体的内部空间中,并且连接到输出轴以与其一起旋转以切割草,而内部空间的螺旋形部分产生旋转气流,从而允许切草在内部空间内旋转。 外壳连接到壳体,并且具有排气通道,其具有与壳体的内部空间连通的入口开口,用于排出由切割刀切割的草并在壳体的内部空间内旋转。 引导构件设置在壳体的内部空间中,用于逐渐改变旋转气流和旋转切草的方向,并且用于将旋转气流和旋转切草引导到外壳的排出通道。

    • A tensioner, in which a bearing of the drive shaft is not necessary and the initial load of the torsion spring is maintained when the tensioner is disassembled, two shaft members that compose a set and that are engaged by screw portions, and a spring that is inserted in the driving unit by fastening onto the shaft members the hooking portions that are located at each end of the spring. The spring is inserted in the set of the shaft members under an appropriate windup condition. One shaft member moves forward from the loaded strength by the spring. The tensioner also includes, beside the driving unit, a case into which the driving unit is inserted, and a system that prevents the driving unit from coming off the case.
    • 一个张紧器,其中不需要驱动轴的轴承并且当张紧器被拆卸时维持扭簧的初始载荷,构成一组并且由螺纹部分接合的两个轴构件和与螺钉部分接合的弹簧 通过将位于弹簧的每一端的钩部紧固在轴构件上而插入驱动单元中。 弹簧在适当的卷起条件下插入到轴构件的组中。 一个轴构件通过弹簧从装载的强度向前移动。 张紧器还包括驱动单元旁边的驱动单元插入的壳体和防止驱动单元脱离壳体的系统。
