    • An adjustable rotating shaft guard includes a base, a first guard half, and a second guard half. A bottom of the first and second guard halves are retained by the base such that they contact each other to fully cover a rotating shaft or coupler. A half sleeve preferably extends outward from at least one end of the first and second guard halves. Preferably, the top of each guard half is fastened to each other. The first and second guard halves are preferably fabricated from a high impact plastic. The bottom area of the first and second guard halves preferably have a plurality of cutting lines which provide a reference for sawing to a specific height. The half sleeves also have a plurality of cutting lines which provide a reference for sawing to a specific length. In a second embodiment, an adjustable rotating shaft guard includes a first sleeve guard half, a second sleeve guard half and two sets of two end cap halves. Each pair of end cap halves are attached to each end of the first and second sleeve guard halves. One or both ends of the first and second sleeve halves may be supported by an adjustable leg set. One or both ends of the first and second sleeve guard halves may be supported by a mounting plate.
    • 可调节的转轴防护罩包括底座,第一护罩半部和第二护罩半部。 第一和第二保护半部的底部由基座保持,使得它们彼此接触以完全覆盖旋转轴或联接器。 半套管优选地从第一和第二保护半部的至少一端向外延伸。 优选地,每个护罩半部的顶部彼此紧固。 第一和第二保护半部优选地由高冲击塑料制成。 第一和第二保护半部的底部区域优选地具有多个切割线,其提供用于锯切到特定高度的参考。 半套还具有多条切割线,其提供用于锯切到特定长度的参考。 在第二实施例中,可调节的旋转轴防护件包括第一套筒保护罩半部,第二套筒防护件半部和两组两个端盖半部。 每对端帽半部分连接到第一和第二套筒保护半部的每个端部。 第一和第二套筒半部的一端或两端可以由可调腿部支撑。 第一和第二套筒保护半部的一端或两端可由安装板支撑。
