    摘要： This invention provides a post hole digger having a first, traverse pivot point, located on the lower section of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.

    摘要翻译： 本发明提供了一种钻孔挖掘机，其具有位于两个手柄构件的下部上的第一横向枢转点和位于叶片组件的中间点处的第二刀片组件枢转点。 因为第一枢轴点是横动枢轴点，所以只需要把手件移动到有限的运动范围内。 另外，第二刀片组件枢转点优选地是偏移枢转点。 因此，由于第二刀片组件枢转点设置在刀片组件上的中点处，与刀片组件的上端相连的手柄件的运动相对于刀片件的下端是相反的 。

    摘要： An improved wheelbarrow includes a pair of legs that are each configured as four-bar linkages and are collapsible. Each of the legs includes an advantageously simple lock for releasably locking the leg in extended and retracted positions. The wheelbarrow includes a frame assembly, a wheel, a tray, and a pair of handles. The frame assembly can be assembled by the manufacturer, and the wheelbarrow can then be provided as a kit in accordance with the present invention that can be assembled by the retailer or the consumer by simply attaching the wheel, the tray, and the handles to the frame assembly. A support block is disclosed which facilitates assembly and strengthens the legs.
