    • Three adjustable supports, positioned at the vertices of a triangle, are used to support one structure from another structure. In one form of the support, a post threaded at its lower end extends from the first structure to a slot in the second structure. A spring is captured between a shoulder on the post and a facing shoulder on the second shoulder at the bottom of the slot. A threaded end of the post extends through an oversize bore in the second structure. A spherical washer has a flat side resting against the outer surface of the second support, and a spherical washer is engaged to the threaded end of the post such that the spherical surface of the washer contacts the spherical surface of the nut to provide freedom of movement.
    • 位于三角形顶点的三个可调节支架用于支撑来自另一个结构的一个结构。 在支撑件的一种形式中,其下端处的螺纹端部从第一结构延伸到第二结构中的狭槽。 弹簧被捕获在柱的肩部和槽的底部上的第二肩部上的相对的肩部之间。 柱的螺纹端延伸穿过第二结构中的过大孔。 球形垫圈具有平坦的侧面抵靠第二支撑件的外表面,并且球面垫圈接合到柱的螺纹端,使得垫圈的球形表面接触螺母的球形表面以提供运动自由 。
