Abstract
An actuator has a linear driving mechanism, an output member, and an elastic member. The linear driving mechanism has a stepping motor, a thread rod assembly, and a linearly moveable member. The threaded rod assembly is connected with the stepping motor. The linearly moveable member is located at a side of the stepping motor and is connected with and driven by the thread rod assembly to reciprocatively move along a power input axis. The output member is disposed on a side of the linearly moveable member and has a capability of linearly moving along a power output axis that is co-axial with the power input axis. The elastic member is connected between the linearly moveable member and the output member to provide an elastic force along the power input axis.
