Abstract
A retractable handle device is provided which includes two sleeves, two inner tubes disposed in the corresponding sleeves, and a handle mechanism that respectively receives the inner tubes on opposing ends thereof. Two position-control devices are located at the bottom end of corresponding inner tubes. The handle mechanism has a press bar mounted in a lower casing thereof. Each position-control device has a locating block fastened to the bottom end of the corresponding inner tube, a flat latch, biased by a spring, engaging a locating hole on the corresponding sleeve to stop the respective inner tube from axial movement relative to the corresponding sleeve. A respective swivel driving element rotates about a pivot pin in each locating block and is coupled to one end of the corresponding flat latch and controlled by the press bar through a respective link to pull the flat latches away from the respective locating holes in the corresponding sleeves, so that the inner tubes can be axially moved relative to the sleeves.
