同时，弹性件531施加给活动块41一个向上的力，以使活动块41的第一侧壁410和第二侧壁411可以分别推动第一臂430的第一端4300和第二臂431的第一端4310，使得第一臂430和第二臂431可以围绕圆杆18转动，从而带动第一臂430的第二端4301和第二臂431的第二端4311转动，直至第一臂430的第二端4301和第二臂431的第二端4311分别与第三限位部27和第四限位部37抵持，由此第一握持部20和第二握持部30向展开方向的运动被限制。
与此同时，第一齿轮553带动第二齿轮555转动，从而带动第一凸块550和第二凸块551转动，而第一凸块550和第二凸块551转动时可以带动第一握持部20和第二握持部30转动，直至第一凸缘16与第一侧面26、第二凸缘17与第二侧面36抵持，由此第一握持部20和第二握持部30向折叠方向的运动被限制。
请参阅图8-图12，本发明的交通工具1000包括以上任一项的方向盘100。
如此，方向盘100占用交通工具1000的空间极大缩小，有利于提升驾驶员的驾驶体验。
具体地，交通工具1000可以是车辆，当车辆启动时，方向盘100从仪表盘下饰板中伸出，在距离方向盘100名义位置(或记忆位置)20％行程时，启动方向盘100的展开功能(即第一握持部20和第二握持部30向展开的方向运动)，可以理解，方向盘100的名义位置指的是方向盘100安装在仪表盘下饰板中的初始位置，20％行程可以是方向盘100从仪表盘下饰板中伸出全程的20％。驱动件51可以通过联轴器15带动第一齿轮553转动，从而使得第一齿轮553带动第二齿轮555转动，进而使得第一握持部20和第二握持部30展开。
当车辆熄火时，驱动件51可以通过联轴器15带动第一齿轮553做与启动时相反的转动，从而使得第一齿轮553带动第二齿轮555转动，进而使得第一握持部20和第二握持部30折叠，最后使得方向盘100重新收纳至仪表盘下饰板中。
