1. An actuator assembly, comprising:
a threaded shaft;
a threaded nut that is threadably coupled to the threaded shaft;
an annular ratchet positioned about the threaded shaft and comprising one or more tracks; and
a pin that extends from the threaded shaft and into the one or more tracks;
wherein:
during a first portion of an actuation process:
the threaded shaft, the annular ratchet, and the pin are configured to rotate together in a first direction; and
rotation of the threaded shaft drives the threaded nut to move along a longitudinal axis along the threaded shaft toward the annular ratchet; and
during a second portion of the actuation process:
the threaded nut contacts the annular ratchet to block rotation of the annular ratchet with the threaded shaft and the pin; and
rotation of the threaded shaft drives the pin to move in the one or more tracks of the annular ratchet to thereby drive the annular ratchet to move toward the threaded nut along the longitudinal axis.
