Abstract : A precision actuator of minimum thickness which provides high output force with low input torque and includes a single-piece metallic rhombus with a drive assembly made up of a right-hand threaded rod that passes through a right-hand threaded side apex of the rhombus connected by a coupling to a left-hand threaded rod that passes through a left-hand threaded side apex opposite the other threaded apex of the rhombus. The right-hand threaded and left-hand threaded rods are secured to the coupling such that the drive assembly rotates as a unit. Right-hand rotation of the drive assembly increases the distance between the threaded apexes while drawing the end apexes closer together and left-hand rotation of the drive assembly draws the threaded apexes closer together forcing the end apexes further apart.
