Abstract
A retaining structure. The retaining structure includes a retaining member on a first track and a pressing block on a second track slidably received in the first track. The retaining member has two resilient legs and the pressing block has two protrusions. When the second track is mounted in the first track and pulled outward to a predetermined position, the legs of the retaining member press against inner sides of the protrusions of the pressing block to prevent inadvertent inward movement of the second track in the first track. When the second track in the predetermined position is pushed inwards by an appropriate force, the protrusions of the pressing block press to deform the legs of the retaining member to allow the protrusions of the pressing block to move across the retaining member, thus allowing inward movement of the second track in the first track.
