    • A dual handled, single throttle trigger trimmer comprising rotating handles and a rotating trimmer head. The rotating handles allow the use of the trimmer in a trimming mode and an edging mode. The device may be readily converted between the two modes and the lawn care worker must not remove either hand from the device while doing so. The conversion is accomplished by rotating the trimmer upper handle about an axis perpendicular to the trimmer driveshaft while simultaneously rotating the trimmer middle handle about an axis parallel to the trimmer driveshaft. The middle handle has a slide fit around the trimmer driveshaft.
    • 双处理,单油门触发修剪器,包括旋转手柄和旋转修剪头。 旋转手柄允许在修边模式和边缘模式中使用修剪器。 该装置可以容易地在两种模式之间转换,并且草坪护理人员在这样做时不得从设备中移除任一只手。 通过围绕垂直于修剪器传动轴的轴线旋转修剪器上部手柄,同时围绕平行于修剪器传动轴的轴线旋转修剪器中间手柄来实现转换。 中间手柄在修剪器传动轴周围具有滑动配合。

    • A chuck to this disclosed which has a central body for including a nose section 6 and a tail section 8. A central portend is formed through the chuck to and a plurality of passageways 12 are angled thereto. Jaws 14 may move through the passageways 12 in response to rotation of a rotatable nut 20 which is in screw thread engagement with the jaws 14. A bearing member 36 is disclosed which sits in a tapered portion between the body for and the nut 20 so that radial displacement of the bearing 36 causes the chuck to be locked against release.

    • The present invention is an arthropod trap including a housing and containment chamber. The housing includes external openings, an overhang, and an internal tube and plate with entry ports. Attracted by bait in the containment chamber, arthropods fly in through the external openings, and then travel through the entry ports in the plate into the containment chamber. Alternatively, arthropods can directly enter the containment chamber through optional entry ports. The containment chamber can be a box or other rigid container, or a bag. This trap can be used to contain or monitor the populations of many different types of flying arthropods, including but not limited to flies, wasps, and yellow jackets.
    • 本发明是一种包括壳体和容纳室的节肢动物捕集器。 壳体包括外部开口,突出端以及具有入口的内部管和板。 节肢动物在遏制室吸引诱饵,节肢动物通过外部开口飞入,然后穿过板中的入口进入收容室。 或者,节肢动物可以通过可选入口直接进入容纳室。 容纳室可以是箱子或其他刚性容器或袋子。 这个陷阱可用于控制或监测许多不同类型的飞行节肢动物的种群,包括但不限于苍蝇,黄蜂和黄色夹克。
