工作原理：通过将支撑柱3连同安装座2在矩形框架1的底部转动，使得支撑柱3和地面保持竖直，拉动安装槽21内的螺纹筒9，在螺纹筒9内转动螺纹杆8，使得螺纹杆8在螺纹筒9拉伸，使得螺纹杆8伸入螺纹孔，从而对支撑柱3进行支撑，保持支撑柱3的稳定，提高沙发整体框架的稳定性，在需要搬运时，将螺纹杆8和螺纹筒9收纳至安装槽21内，插入连接杆，对螺纹杆8进行限位，从而支撑装置的收纳，再转动支撑柱3，使得支撑柱3和矩形框架1保持水平，通过第一磁块7和第二磁块22的相互配合，使得收纳后的支撑柱3保持稳定，减少运输途中支撑柱3的晃动，通过握槽17拉动限位板10，使得限位板10移出固定槽19，从而限位板10底部的导杆18脱离导孔20，便于弹力杆11的更换，提高弹力杆11操作的便利性，通过拉动连接绳31，带动连接环29在装配槽30内移动，使得活动杆28在固定套27上移动并脱离插块13，从而便于将固定框14和海绵垫15移出，便于对海绵垫15进行更换，在安装时，插块13插入插孔12内，在弹簧26的弹力下，挤压挡块25，使得活动杆28插入插块13内，从而对海绵垫15进行限位，减少海绵垫15在矩形框架1上的滑动，通过将沙发套16套在海绵垫15上，使用固定螺栓33 将沙发套16固定在海绵垫15上，便于保持沙发套16套后的稳定。
