Abstract: Provided is an apparatus with automatic belt tensioning. A winding seat includes a first gear and a winding portion fixed at the first gear. A belt is windable around the winding portion, and the first elastic element is connected with the winding portion thus to wind the belt around the winding portion. A rotation preventing element includes a protrusion. When the protrusion retains the first gear, the winding portion is locked to prevent the belt being wound. When the belt is pulled, it drives the protrusion to be separated from the first gear and drives the winding portion to rotate. When the belt is released and the winding speed of the belt is decreased to a certain degree, the protrusion retains the first gear to prevent the belt being wound.

Abstract: An electronic device connects to an external host.
