本实用新型的有益效果为：应用该装置，可以实现车辆的展开和折叠，并且在折叠过程中柔度好，避免强度冲撞，使用安全方便。
前把架与踏板活动连接，座椅支撑杆通过转轴与踏板活动连接，所述前把架设置与座椅支撑杆末端相配合挡件。使用者可以坐在座椅上，双脚踏在踏板上，扶着前把骑行，整车结构合理，设计简约，重量轻，体积小，便于折叠，容易携带，存放和骑行都十分方便。
所述转轴设置阻尼器，折叠或者打开座椅支撑杆，即使初始力量很大，座椅支撑杆也不会迅速运动碰撞踏板或前把架，在阻尼器的作用下缓缓闭合或张开。
所述挡件和座椅支撑杆末端设置磁铁，展开状态下，座椅支撑杆末端和挡件吸附在一起，避免支撑杆产生向两侧的侧滑，当骑行者从座椅上下来的时候，座椅支撑杆在磁铁作用下依然会保持展开状态，不会自行闭合，当操作者需要折叠闭合支撑杆时只需上推座椅克服磁力即可。
所述转轴设置侧切面，侧切片与轴体之间设置弹簧，座椅支撑杆绕转轴转动时需要克服侧切面的弹性阻力，保证转动速度不致过快。侧切面会导致座椅支撑杆在某角度停住，当外力继续施加时，侧切片压迫弹簧收缩，座椅支撑杆继续转动。
所述转轴轴架设置胶垫，胶垫塞在座椅支撑杆和轴架之间，保证转动的柔度，并起到一定的减震作用，转动速度也不会过快，防止夹伤手指。
所述挡件设置为凸块，磁铁相应的设置在凸块下方，座椅支撑杆顶在凸块下方，凸块设置在前把架，驾驶者坐在座椅上时凸块可以阻挡座椅支撑杆继续上挑，从而固定住座椅支撑杆的角度。强度高，稳定性好。
所述挡件设置为下端开放的凹型槽，磁铁相应的设置在凹型槽顶部，座椅支撑杆顶在凹型槽的顶部，挡件设计的隐藏性好，无需额外的凸出结构，设计简约，一体性强。
