    • An extendible rod locking sleeve structure consisting of a U-shaped seating sleeve having a small and a large facing annular opening and, furthermore, a bolt or an eccentric lever perpendicularly disposed at the back side of the center section capable of reversible forward engagement by thread fastening or an articulated thrusting motion such that both the inner rod and the outer rod comprising an extendible rod inserted through the two annular openings become fully locked down at the upper and lower positions of the ensleeved area. Among the features of the present invention, the seating sleeve upper and lower annular openings have inwardly protruding curved insertional stop plates formed along the superficial lateral portions of one or both of their interior edges that are utilized for nesting into the intervallicly arrayed annular grooves in the walls of one or both the inner rod and the outer rod, enabling the insertional stop plates enslotted into the annular grooves to effectively achieve stable lock down capability.
    • 一种可延伸杆锁定套筒结构,其由具有小的和面向大的环形开口的U形底座套筒组成,此外,垂直地设置在中心部分的后侧的螺栓或偏心杆能够通过螺纹 紧固或铰接推动运动,使得内杆和包括插入穿过两个环形开口的可伸缩杆的外杆两者完全锁定在所述被包围区域的上部和下部位置。 在本发明的特征中,座套筒上下环形开口具有向内突出的弯曲插入止挡板,沿其一个或两个内边缘的表面侧部形成,用于嵌入到金属间排列的环形槽中 一个或两个内杆和外杆的壁,使得插入环形槽中的插入止挡板能够有效地实现稳定的锁定能力。
