The invention discloses a folder, and relates to the technical field of folders, the folder comprises a rotating plate, the bottom of the rotating plate is provided with a thrust safety column, one side of the thrust safety column is provided with a safety fixing screw, the thrust safety column is connected with the rotating plate through the safety fixing screw, and one side of the thrust safety column is in threaded connection with an adjusting ejector rod. The anti-thrust safety column and the adjusting ejector rod are limited through the safety fixing screw and are fixed in the rotating plate, each part is installed in the two installation plates in a closed safety mode, each connection point is provided with an anti-loosening and anti-falling design, the number of the parts in the whole rotating plate is six, and the anti-loosening and anti-falling functions are achieved. And finally, only one safety fixing screw is unlocked and locked, so that the loosening probability is extremely low, even if the possibility of loosening and falling occurs, other parts cannot fall off, the self-locking safety of the safety fixing screw is not changed, the probability of personnel tumbling cannot be caused, and the ultra-strong safety protection capability is formed.

    本发明公开了折叠器,涉及折叠器技术领域,包括转动板,所述转动板底部设置有止推保险柱,所述止推保险柱一侧设置有保险固定螺丝,所述止推保险柱与转动板通过保险固定螺丝连接,所述止推保险柱一侧螺纹连接有调整顶杆。本发明通过保险固定螺丝对止推保险柱和调整顶杆进行限位,且使止推保险柱和调整顶杆固定在转动板的内部,每个零件都是封闭式保险安装在两个安装板的内部,每个连接点都有防松掉落设计,整个转动板内部的零件总共只有六个,且最后只有一个保险固定螺丝是开放锁定即可,松动概率极低,即使有松动掉落可能,但也不会造成其它的部件掉落,它的自锁安全性不变,也不会造成人员摔跤概率,构成超强的安全防护能力。
