An apparatus comprising: a frame; an actuator is attached to the frame and is slidably movable relative to the frame along a linear axis, and a helical member within the frame and is rotatably movable relative to the frame about a helical axis of the helical member, where the helical axis is parallel to the linear axis, where the actuator and the helical member are configured to cooperate with each other, such that (a) movement of the actuator in a first linear direction along the linear axis causes the helical member to correspondingly rotate about the helical axis in a first rotational direction, and (b) movement of the actuator along the linear axis in a second linear direction opposite the first linear direction causes the helical member to correspondingly rotate about the helical axis in a second rotational direction opposite the first rotational direction.
一种装置,包括:框架;致动器,附接至框架并且可相对于框架沿着线性轴线可滑动地移动,以及螺旋构件,位于框架内并且可相对于框架围绕螺旋构件的螺旋轴线可旋转地移动,其中,螺旋轴线平行于线性轴线,其中,致动器和螺旋构件配置为彼此协作,使得(a)致动器沿着线性轴线在第一线性方向上的运动引起螺旋构件围绕螺旋轴线在第一旋转方向上对应地旋转,并且(b)致动器沿着线性轴线在与第一线性方向相反的第二线性方向上的运动引起螺旋构件围绕螺旋轴线在与第一旋转方向相反的第二旋转方向上对应地旋转。
