    • The present invention provides an adjustable drywall sander capable of imparting more than one type of motion. In an exemplary embodiment, the sander includes a power unit with a motor and a sanding assembly coupled to the power unit. A telescopic support arm assembly is coupled to the sanding assembly and the power unit for supporting the sanding assembly. The telescopic support arm assembly includes a first support arm with a first and a second end and a second support arm with a first and second end. The first end of the first support arm being coupled to the power unit and the second end of the second support arm being coupled to the sanding assembly. A collapsible drive shaft is substantially enclosed by the telescopic support arm assembly. The telescopic support arm assembly and the collapsible drive shaft allow the length of the telescopic assembly to be adjusted.
    • 本发明提供了一种能够施加多于一种类型的运动的可调式干式砂光机。 在示例性实施例中,砂光机包括具有马达的动力单元和联接到动力单元的砂磨组件。 伸缩支撑臂组件联接到砂磨组件和用于支撑砂磨组件的动力单元。 伸缩支撑臂组件包括具有第一和第二端的第一支撑臂和具有第一和第二端的第二支撑臂。 第一支撑臂的第一端联接到动力单元,第二支撑臂的第二端联接到砂磨组件。 可伸缩的驱动轴基本上由伸缩支撑臂组件封闭。 伸缩支撑臂组件和可折叠驱动轴允许调节伸缩组件的长度。

    • The present invention is directed to an elevating mechanism, in particular to an elevating mechanism for routers, is configured for easy micro adjustment and coarse or macro adjustment. In an embodiment, a power tool includes a base configured to adjustably receive a motor housing for operating a working tool. A worm drive is pivotally coupled, in an eccentric configuration, to an eccentric lever. The eccentric lever is adjustably coupled to at least one of the housing or the base such that the eccentric lever is operable to cause the worm drive to be positioned into an engaged position with a rack assembly and a released position wherein the worm drive is remote from the rack assembly. The elevating mechanism is operable to permit rotational micro adjustment and macro manual adjustment wherein the worm drive is remote from the rack assembly for permitting coarse adjustment of the motor housing with respect to the base.
    • 本发明涉及一种升降机构,特别是用于路由器的升降机构,其构造为容易进行微调和粗调或微调。 在一个实施例中,电动工具包括被配置为可调节地接收用于操作工作工具的电动机壳体的基座。 蜗杆驱动器以偏心构造枢转地联接到偏心杆。 所述偏心杆可调节地联接到所述壳体或所述基座中的至少一个,使得所述偏心杆可操作以使得所述蜗杆驱动器定位成与齿条组件接合的位置和所述释放位置,其中所述蜗杆驱动器远离 机架组件。 升降机构可操作以允许旋转微调和宏观手动调节,其中蜗杆驱动器远离齿条组件,用于允许相对于基座的马达壳体的粗调。
