The invention provides a bicycle rotary folder, and belongs to the technical field of bicycle folders. Comprising a first bicycle frame rod and a second bicycle frame rod which are arranged on a bicycle frame, and the sides, close to each other, of the first bicycle frame rod and the second bicycle frame rod are each provided with two connecting parts which can abut against each other through rotation. Wherein one connecting part is sleeved with a locking part capable of fixing the relative positions of the two connecting parts after the two connecting parts abut against each other. By arranging the connecting component and the locking component, timely and effective feedback is obtained in the frame unfolding process, the trial and error links in the adjusting process are avoided, and the time needed for unfolding the folding bicycle frame is shortened; by arranging the connecting adjusting handle and the connecting sleeve, when the frame is unfolded, force needed for buckling the adjusting handle is constant and cannot be increased due to the fact that the connecting sleeve locks the first connecting circular truncated cone and the second connecting circular truncated cone, the folding device is friendly to people with small force, and the using difficulty of the folding device is reduced.

    本发明提供一种自行车旋转折叠器,属于自行车折叠器技术领域;包括设置在自行车车架上的第一车架杆和第二车架杆,所述第一车架杆和第二车架杆相互靠近的一侧分别设置有可通过转动实现抵接的两个连接部件,其中一个所述连接部件上套设有可在两个连接部件抵接后固定两个连接部件相对位置的锁紧部件。本发明通过设置连接部件和锁紧部件在车架展开过程中获得及时有效的反馈,避免了调节过程中的试错环节,降低了折叠自行车车架的展开需时间,通过设置连接调节把和连接套筒使得车架展开时扣合调节把需的力恒定且不会因连接套筒锁紧第一连接圆台和第二连接圆台而增加,对于力气较小的人群友好,降低了折叠器的使用难度。
