A carpet stretcher device has an automatic adjusting tube that changes length with telescoping motion of an inside tube and an outside tube. A housing is mounted on the outside tube, and at least one lever is connected to the housing. A hand lever controls the motion of a spring-loaded rotating arm with a locking button positioned within the housing to insert and remove the locking button from holes in the tubes. When lifted away from the housing, the hand lever releases the rotating arms, which rotate to remove the locking button from holes in the tubes and thereby allow the tubes to telescope. The carpet stretcher may also have a floor lever that retracts when the device contacts a floor surface and extends when the device is lifted off a floor surface. When extended, the floor lever also releases the rotating arms, thereby allowing the tubes to telescope.
