Abstract
In an example, a space adjuster may comprise a cam shaft, a first fin disposed on a first end of the cam shaft, a second fin disposed on a second end of the cam shaft, opposite from the first end, and a cam lug disposed on the cam shaft in between the first end and the second end. The first fin may have a first profile to transfer a first longitudinal force into a first rotation of the cam shaft, and the second fin may have a second profile to transfer a second longitudinal force into a second rotation of the cam shaft, opposite to the first rotation. A cam surface of the cam lug may be spaced increasingly farther away from a longitudinal axis of the cam shaft throughout the first rotation of the cam shaft.
