为了进一步完善，所述轮轴的长度大于轴筒长度与轮板直径之和。
进一步完善，所述轮面宽度大于轮轴直径。
进一步完善，所述固定壳体的腿部均布有若干个十字形透气孔，方便腿部透气。
进一步完善，所述固定壳体鞋部两侧各设有三个圆形透气孔。方便脚部透气。
本发明有益的效果是：1、本发明通过按压气泵球向矩形缸筒内充气，在气压作用下活塞板下移，将固定壳体顶高，实现了患者躺在床上时可以将脚部垫高的目的，提高了舒适性和疗效；2、所述活塞板下端固定有轴筒，轴筒内设有轮轴，轮轴与轴筒内孔配合转动连接，轮轴两端设有可折叠轮子，可折叠轮子在床上时折叠收起，可以作为支撑底座，使踝关节固定器不容易向两侧偏移，有利于踝关节矫正，下床移动的可以将可折叠轮子打开，一只脚滑行，另一只脚推动，方便省力的进行移动，比单脚跳移动更加安全。

具体实施方式
下面结合附图对本发明作进一步说明：
参照附图：本实施例中一种踝关节固定器，包括固定壳体1和固定壳体1上的魔术贴固定带2，所述固定壳体1鞋底的伸缩气缸，伸缩气缸包括矩形缸筒3、活塞4、活塞板5和端盖6，所述矩形缸筒3左侧壁固定连接固定壳体1，矩形缸筒3下端为开口并设有端盖6，矩形缸筒3内设有可以上下移动的活塞板5，活塞板5上端固定有活塞4，活塞4与矩形缸筒3内孔配合密封滑动连接，所述活塞板5的长度小于矩形缸筒3长度，活塞板5下端穿出端盖6上的通口，所述矩形缸筒3顶部设有接气头7，接气头7连接气管8，气管8连接气泵球9，气泵球9与气管8之间设有阀门10，所述活塞板5下端固定有轴筒11，轴 筒11内设有轮轴12，轮轴12与轴筒11内孔配合转动连接，所述轮轴12两端设有可折叠轮子，可折叠轮子包括圆形的轮板13，轮板13右侧周边固定连接有筒形的轮面14，所述轮板13右侧壁上设有两个安装板16，两个安装板16与轮轴12侧部进行转动连接，所述轮轴12的端面中心设有盲孔17，盲孔17内设有可伸缩的销钉19，所述轮板13中心设有销孔20，销孔20与销钉19配合连接，所述销钉19内端与盲孔17之间设有弹簧21，销钉19外端设有球头22，所述轮面14侧壁上设有折叠后容纳轮轴12的凹口23。
工作原理：使用时，通过按压气泵球9向矩形缸筒3内充气，在气压作用下活塞板5下移，将固定壳体1顶高，实现了患者躺在床上时可以将脚部垫高的目的，提高了舒适性和疗效，通过阀门10可以放掉矩形缸筒3内的气体，使固定壳体1高度下降；所述活塞板5下端固定有轴筒11，轴筒11内设有轮轴12，轮轴12与轴筒11内孔配合转动连接，所述轮轴12两端设有可折叠轮子，下床移动的可以将可折叠轮子展开，即将轮板13转动90度，使销钉19连接轮板13中心的销孔20，然后一只脚滑行，另一只脚推动，方便省力的进行移动，比单脚跳移动更加安全；在床上时，按下销钉19将可折叠轮子收起，轮轴12收纳进凹口23，此时可折叠轮子可以作为支撑底座，使踝关节固定器不容易向两侧偏移，有利于踝关节矫正。
虽然本发明已通过参考优选的实施例进行了图示和描述，但是，本专业普通技术人员应当了解，在权利要求书的范围内，可作形式和细节上的各种各样变化。
