The frame 33 is arranged at both ends of the base 31. The frame 33 is connected to the base 31 through the rotating shaft structure 32, so that the curved and straight support conversion structure 4 can rotate with the rotating shaft structure 32 to adjust the curvature of the support surface. A torsion spring 38 is provided around the axis on the rotating shaft structure 32. The torsion spring 38 is used to provide damping for the rotating support surface, thereby realizing follow-up adjustment of the support surface and facilitating user operation. The frame 33 is arranged around the guide seat 34 to prevent foreign objects from invading and getting stuck.

更优选地，机架33上设有通过通孔331，推拉杆431与通孔331滑动连接，机架33靠近导向座34设置，对推拉杆431起到稳定和导向作用，机架33的端部与支撑件41固定连接，为支撑件41提供支撑力。More preferably, a through hole 331 is provided on the frame 33, and the push-pull rod 431 is slidably connected to the through hole 331. The frame 33 is arranged close to the guide seat 34 to stabilize and guide the push-pull rod 431. The end of the frame 33 is fixedly connected to the support member 41 to provide supporting force for the support member 41.

该曲直屏幕两用支架的工作过程如下：The working process of the curved and straight screen dual-purpose bracket is as follows:

在支撑直面屏幕时，推动支撑件41绕转轴结构32的轴心转动，连杆组件43上的推拉杆431端部的凹槽结构434的内侧壁与导向座34上的倾斜部341抵触，同时推拉杆431绕轴转动，导向座34拉动连杆组件43动作，连杆组件43拉动最外侧的支撑件41收紧，使得多个支撑件41形成的支撑面绷直形成平面；当支撑曲面屏幕时，推动支撑件41绕转轴结构32的轴心反向旋转，导向座34对连杆组件43的拉力消失，多个支撑件41在第一弹性元件424的作用下收缩，使得多个支撑件41形成的支撑面向内收缩形成带有弧度的曲面，调节旋转角度的大小可以改支撑面的弧度大小。When supporting a straight screen, the support member 41 is pushed to rotate around the axis of the rotating shaft structure 32, and the inner wall of the groove structure 434 at the end of the push-pull rod 431 on the connecting rod assembly 43 contacts the inclined portion 341 on the guide seat 34. At the same time, the push-pull rod 431 rotates around the axis, and the guide seat 34 pulls the connecting rod assembly 43 to move, and the connecting rod assembly 43 pulls the outermost support member 41 to tighten, so that the support surface formed by the multiple support members 41 is straightened to form a plane; when supporting a curved screen, the support member 41 is pushed to rotate in the opposite direction around the axis of the rotating shaft structure 32, and the pulling force of the guide seat 34 on the connecting rod assembly 43 disappears. The multiple support members 41 shrink under the action of the first elastic element 424, so that the support surface formed by the multiple support members 41 shrinks inward to form a curved surface with an arc, and the arc size of the support surface can be changed by adjusting the rotation angle.
