Abstract
An extendible and retractable actuator comprises a motor, two screws and an extendible and retractable sleeve assembly. The motor cooperates with the screws to drive the extendible and retractable sleeve assembly to extend and retract simultaneously, so as to reduce the extending and retracting time and to simplify the structure of the extendible and retractable actuator.
