背景技术
随着用户的需求越来越多，现有的显示器支架除了常规的升降功能外，其还具备可旋转的功能，具体地，带有可旋转功能支架能够使得显示器顺时针或逆时针旋转，从而实现横屏和竖屏的切换，以满足不同用户的需求。
现有技术中的旋转支架，如CN212251800U专利所示，该专利中的旋转支架虽然能够使得显示器旋转，但是当用户在显示器处于横屏状态下搬运该类旋转支架时，由于旋转支架缺乏锁定结构，显示器容易在搬运过程中发生旋转，給用户带来一定安全隐患。
因此，寻找一种能够解决上述技术问题的一种带锁定结构的旋转支架及电子设备成为本领域技术人员所研究的重要课题。

所述第一弹簧22未被压缩时，所述卡块2002卡入于所述档位卡槽2101内以限制所述压柱20和所述轴座17相对于所述第一分段1901转动；
所述压柱20受压沿所述第一分段1901移动以压缩所述第一弹簧22时，所述卡块2002脱离所述档位卡槽2101。
需要说明的是，操作人员未对压柱20进行按压时，压柱20上的卡块2002卡入于阻挡片21上的档位卡槽2101中，此时，压柱20和轴座17均不能相对于第一分段1901转动，若需要对该底座8进行折叠时，操作人员可通过按压压柱20，使得压柱20沿着第一分段1901移动以对第一弹簧22进行压缩，此时压柱20上的卡块2002脱离档位卡槽2101，压柱20和轴座17可以相对于第一分段1901转动，操作人员控制轴座17转动至合适的折叠角度后，压柱20受到第一弹簧22的反向作用力，压柱20上的卡块2002自动卡入于与该折叠角度相对应的档位卡槽2101上以限制压柱20和轴座17相对于第一分段1901旋转，通过上述的设计，操作人员在需要对该底座8包装出货前，预先对该底座8进行折叠，折叠后的底座8变为类似于平面的结构，以缩小底座8占用包装盒的空间，使操作人员可利用较小体积的包装盒对底座8进行包装，进一步降低了运输成本。
进一步地，还包括卡销23和第二弹簧24；
所述底座8的底面与所述轴座17相对应的位置上开设有安装孔801，所述轴座17与所述安装孔801相对应的位置上开设有与所述中空腔体连通的通孔1702，所述通孔1702的轴线与所述安装孔801的轴线相重合，所述通孔1702的轴线与所述第一分段1901相垂直，所述通孔1702的轴线处于所述压柱20的移动轨迹上；
所述卡销23经所述安装孔801***于所述通孔1702内，所述第二弹簧24位于所述通孔1702内，且缠绕于所述卡销23上，所述卡销23上设置有销肩2301，所述第二弹簧24的第一端与所述通孔1702的孔壁17021抵接，所述第二弹簧24的第二端与所述销肩2301抵接；
所述第二弹簧24未被压缩时，所述卡销23的底端外露于所述安装孔801外；
所述卡销23的底端受力往通孔1702内移动以压缩所述第二弹簧24 时，所述卡销23的顶端穿出所述通孔1702且位于所述中空腔体内以阻挡压柱20往所述第二分段1902的方向移动。
需要说明的是，上述的设计是能够防止操作者误操作，具体地，当底座8本体平放于桌面上时，此时，卡销23的底端受到桌面向上的作用力，此时，卡销23受力在通孔1702内往上移动，卡销23的顶端克服第二弹簧24的弹力穿出通孔1702，且停留在中空腔体内，具体地，卡销23的顶端停留在压柱20受压移动的轨迹上，此时，无论怎样按压压柱20，压柱20都不会对第一弹簧22进行压缩，压柱20上的卡块2002也无法脱离档位卡槽2101，通过上述的设计，从而避免了用户正常使用该底座8时，误操作压柱20导致整个底座8旋转，进而导致显示器摔倒的情况发生。若底座8本体离开桌面，在第二弹簧24的弹力作用下，卡销23在通孔1702内往下移动，卡销23的底端外露于底座8本体的底面。
进一步地，还包括按钮盖18，所述压柱20远离所述第一弹簧22的一侧面与所述按钮盖18固定连接；
所述第一弹簧22未被压缩时，所述按钮盖18与所述轴座17远离所述第二分段1902的一侧面相齐平。
需要说明的是，通过上述的设计，可更加方便用户或者操作人员对压柱20进行按压。
