Zusammenfassung:A mechanical stepper and a method of incrementally actuating a device. The insert is disposed within the housing. The housing has a chamber and a step sleeve located within the chamber. The step sleeve includes a first stop member having a balanced position defined by a first balanced diameter and a second stop member having a balanced position defined by a second balanced diameter smaller than the first balanced diameter. The insert includes a first protrusion. The insert moves through the housing, and movement of the insert through the housing is incrementally restricted via the first protrusion by varying a diameter of the first stop member and a diameter of the second stop member. 一种机械步进器及递增地致动装置的方法。插入件放置在壳体内。该壳体具有腔室和位于该腔室内的步进套筒。该步进套筒包括具有由第一平衡直径限定的平衡位置的第一止动构件和具有由小于该第一平衡直径的第二平衡直径限定的平衡位置的第二止动构件。该插入件包括第一突起。该插入件移动穿过该壳体,并且该插入件穿过该壳体的运动通过改变该第一止动构件的直径和该第二止动构件的直径经由该第一突起递增地限制。
