    • Embodiments of the present invention provide a jaw apparatus that is tied to a stable anchor (e.g., a vehicle) and that holds wood off the ground in a stable manner to enable cutting by a user. The jaw apparatus can include a main shaft that defines a shaft axis. The main shaft can have a first end and a second end. The first end of the main shaft can have an insertion portion that is configured to be inserted into a trailer-hitch-like receptacle (e.g., a trailer hitch receptacle). The jaw apparatus can include an indentation structure coupled to the second end of the main shaft. The indentation structure can form an indentation, which can have interior surfaces. The interior surfaces can extend upwardly and away from the main shaft. The interior surfaces can be configured to exert upward force on the piece of wood when received in the jaw apparatus. The jaw apparatus can include one or more bars coupled to the main shaft at a bar connection location between the first and second ends of the main shaft. Each of the one or more bars can extend upwardly and away from the main shaft in a direction toward the second end of the main shaft. Each of the one or more bars can have a downward facing surface configured to exert downward force on the piece of wood when received in the jaw apparatus.
    • 本发明的实施例提供了一种连接到稳定的锚(例如,车辆)并且以稳定的方式将木材从地面上保持以使用户能够切割的颚式装置。 钳口装置可以包括限定轴线的主轴。 主轴可以具有第一端和第二端。 主轴的第一端可以具有被配置成插入拖车式接收器(例如拖车接头插座)中的插入部分。 钳口装置可以包括联接到主轴的第二端的凹陷结构。 压痕结构可以形成一个可以具有内表面的压痕。 内表面可以向上延伸并远离主轴。 内表面可以构造成当被接收在颚式装置中时在木片上施加向上的力。 颚装置可以包括在主轴的第一和第二端之间的杆连接位置处联接到主轴的一个或多个杆。 一个或多个杆中的每一个可以在朝向主轴的第二端的方向上向上延伸并远离主轴。 所述一个或多个杆中的每一个可以具有向下的表面,所述表面构造成当被接纳在所述钳口装置中时在所述木片上施加向下的力。

    • Embodiments of the present invention provide pulley apparatuses that can be easily incorporated into block-and-tackle configurations. In some embodiments, a rope can be easily dropped into place and removed, rather than having to be threaded in. For example, the pulley housing can include a rope channeling structure near the end opposite the aperture, and the rope channeling structure can facilitate introducing the rope into engagement with the wheel and/or removing the rope from engagement with the wheel. In some embodiments, the rope channeling structure can prevent the rope from inadvertently becoming removed from the pulley. Some pulley apparatuses can comprise a minimal number of parts, which can significantly simplify the manufacturing process and provide for a more consistent final product.
    • 本发明的实施例提供了可以容易地并入到块和配置构造中的滑轮装置。 在一些实施例中,绳索可以容易地落入到位并被移除,而不是必须被螺纹连接。例如,滑轮壳体可以包括在与孔相对的端部附近的绳索通道结构,并且绳索引导结构可以便于引入 绳子与车轮接合和/或将绳索从车轮上脱离。 在一些实施例中,绳索引导结构可以防止绳索无意中从滑轮移除。 一些滑轮装置可以包括最少数量的部件,其可以显着简化制造过程并提供更一致的最终产品。
