    • A power tool and system for trimming and cutting vegetation are disclosed. A method of attaching a working assembly, such as blade carrier assembly, to a power tool is also disclosed. The power tool includes interchangeable cutting elements that can be readily attached and detached from a main body portion without any preliminary alignment steps. The main body portion of the power tool includes a selectively actuatable motor including a rotary output and a rotary drive element including a resiliently biased drive pin. Blade carrier assemblies are capable of being selectively and removably attached to the main body portion and each include a moveable blade portion having a drive pin slot. Upon attaching a blade carrier assembly to the main body portion and actuating the motor, the resiliently biased drive pin is rotatable to a position such that the drive pin is resiliently forced into the drive pin slot of the working piece to actuate the working assembly.
    • 公开了一种用于修剪和切割植被的电动工具和系统。 还公开了将工作组件(例如叶片承载组件)附接到动力工具的方法。 电动工具包括可互换的切割元件,其可以容易地从主体部分附接和分离,而没有任何初步对准步骤。 电动工具的主体部分包括可选择性致动的电动机,其包括旋转输出和包括弹性偏置的驱动销的旋转驱动元件。 叶片载体组件能够选择性地和可移除地附接到主体部分,并且每个都包括具有驱动销槽的可移动叶片部分。 在将叶片载体组件附接到主体部分并致动马达时,弹性偏置的驱动销可旋转到这样的位置,使得驱动销弹性地被迫进入工件的驱动销槽中以致动工作组件。

    • A portable, hand-operated trimmer has a head module that is removably connected to a power control module. The head module has a power head enclosing an electric motor that is operatively connected to a trimming blade. The power head is selectably settable in a plurality of angular positions with respect to a head support, including a neutral position representing 0 degree rotation, 45 degree flexion and dorsiflexion positions, and 90 degree flexion and dorsiflexion positions. The power head also encloses a stator cartridge that is connected to the housing of the power head by a plurality of fastening members. The head support rotates about the stator cartridge and is engaged by way of a movable engagement pin that is received within a selected recess defined in the stator cartridge. The power head housing and stator cartridge further define molded sockets to receive corresponding pivot arms of the head support. An O-ring is disposed about one of the pivot arms to dampen free rotation. The power control module provides power to the power head through a removable rechargeable battery or through direct connection to conventional household power.
    • 便携式手动修剪器具有可移除地连接到电源控制模块的头模块。 头模块具有包围可操作地连接到修剪刀片的电动机的动力头。 动力头可选择地设置在相对于头部支撑件的多个角度位置中,包括表示0度旋转,45度屈曲和背屈位置的中立位置以及90度屈曲和背屈位置。 动力头还包围定子盒,该定子盒通过多个紧固构件连接到动力头的壳体。 头部支撑件围绕定子盒旋转,并通过可移动的接合销接合,该可动接合销被容纳在限定在定子盒中的所选择的凹部内。 动力头壳体和定子筒进一步限定模制插座以接收头部支撑件的相应枢转臂。 O形环围绕其中一个枢转臂设置以阻止自由旋转。 电源控制模块通过可拆卸的可再充电电池或通过直接连接到常规家用电源为电源头提供电源。

    • The distance between the clamps at opposed ends of a shoulder rest bridge adjustable in infinitely fine increments by utilizing a pressure plate which, in an engaged mode, presses a brake member made from an elastomer, particularly soft rubber, against the underside of the bridge body. The pressure plate is actuated by a pivotable latch having a lever and co-operating with a non-rotatable bearing member having a ramp surface complementary in the direction of incline and in pitch with the ramp surface of the pivotable latch. A supplementary camming mechanism provides, upon hand displacement of one of the clamps towards the other into engagement by both with the instrument, an additional motion of the one clamp toward the instrument thus increasing the clamping force holding the shoulder rest to an instrument.
    • 通过利用压板可以以无限微细的增量可调节肩座的相对端之间的距离,该压板在接合模式中将由弹性体制成的制动构件,特别是软橡胶压靠在桥体的下侧 。 压板由具有杠杆的可枢转闩锁致动,并且与不可旋转的支承构件协作,该不可转动的支承构件具有在倾斜方向上互补的倾斜表面,并且与可枢转闩锁的斜面相对应。 辅助凸轮机构提供了当夹具中的一个朝向另一个夹具移动时通过两者与仪器的接合,使得一个夹具朝向仪器的附加运动,从而增加将肩部固定到仪器上的夹紧力。
