The present invention enables the actuator to run more stably and at least doubles the service life of the product; reduces the requirement of the precision of parts such as motor housing and back fixture, and ensures that the service life of the product meet requirements even when the dimension of a few parts is inaccurate; and therefore eliminates the abnormal noise generated by the spindle of the actuator.
