  • Adjusting mechanism and laser collimator having the same
    Patent number: 9952402
    Abstract: An adjusting mechanism is disclosed. The adjusting mechanism has a differential, first and second stepping motors engaging with the differential, a screw rod connected to the output shaft of the differential such that the screw rod rotates along with the rotation of the output shaft, and a moving block threadably connected to the screw rod to permit motion of the moving block along the longitudinal axis of the screw rod. The output shaft of the adjusting mechanism rotates according to the rotation of the first and second stepping motors, so as to drive the movement of the moving block along the screw rod.
    Type: Grant
