请进一步参阅图8，优选地，第一定位杆161、第二定位杆162、第三定位杆163都为阶梯杆16，阶梯杆16包括第一杆体164、第二杆体165和第三杆体166，第一杆体164与承载架10连接，第二杆体165设于第一杆体164与第三杆体166之间，且第一杆体164的外径和第三杆体166的外径都大于第二杆体165的外径，各形状记忆合金线40的中部分别勾设于各阶梯杆16的第二杆体165上，保证晃动过程中形状记忆合金线40不脱落，同时，阶梯杆16可直接一体成型于座体13上，也可以通过任意一种现有的装配方式装配于座体13上，本实施例中的阶梯杆16安装于座体13上，这样可以简化承载架10的结构、降低承载架10的制作成本。

本发明的应用于潜望式镜头模组的棱镜装置1利用若干形状记忆合金线40驱动支撑复位组件20上的棱镜30在承载架10内可绕第一旋转中心轴转动或者绕第二旋转中心轴转动，使得棱镜30在形状记忆合金线40的驱动作用下能自动校正角度，应用于潜望式镜头模组的棱镜装置1的成像角度更广，其成像效果更好。形状记忆合金线40可由程序发出指令以使其形成记忆效应产生驱动力。
具体操作时，如图1所示，当第一形状记忆合金线41通电发热缩短时，支撑复位组件20受到斜向下的拉力，从而使得支撑复位组件20以滚珠50为支点绕虚线M所指示的方向为旋转轴沿一个方向转动；当第二形状记忆合金线42通电发热缩短时，棱镜30相对于固定座实现绕虚线M所指示的方向为旋转轴向另一相反方向转动；当第三形状记忆合金线43通电发热缩短时，棱镜30可相对于固定座绕X轴所指示的方向为旋转轴沿一个方向转动；当第四形状记忆合金线44通电发热缩短时，棱镜30可相对于固定座绕X轴所指示的方向为旋转轴的另一相反方向转动。本申请的形状记忆合金线40也可以称之为SMA线，在此不作详细描述。
