所述限位件为围板，所述围板固定安装在所述固定板的边缘，所述围板呈U型，所述U型的开口朝向主支撑调节臂的固定端。
所述从动臂设置有齿轮的一端设置有凸起32，所述固定板朝向从动臂的一面设置有与所述凸起相匹配的凹槽44，所述凸起安装在所述凹槽内，使两个所述从动臂分别以凸起为轴在U型的开口处呈剪式撑开。
所述固定件还包括盖板45，所述转轴穿过所述转动端与所述盖板连接。
所述手机支架还包括固定座，所述固定座与所述盖板可拆卸连接。
所述固定端与所述手机挂臂的一端通过锁紧旋钮5连接，所述锁紧旋钮穿过所述固定端与所述手机挂臂的一端螺纹连接。
本实用新型手机支架可用于车内环境中，通过拉动手机挂臂调节距离放置手机。然而现有的挂臂式支架设计，双挂臂需要单独掰动调节角度与距离，操作繁琐。新型的支架结构让左右挂臂同时位移并始终保持平行状态展开，操作更加快捷方便。
以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，对于本领域的技术人员来说，本实用新型可以有各种更改和变化。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
