ABSTRACT:
A coupling structure includes a first slide member, a second slide member slidably connected to the first slide member so as to be slidable relative to each other, and a spring member. The spring member has two opposite ends and a plurality of resilient turnings arranged in a predetermined sequence so as to have the same turning direction such that the resilient turnings are juxtaposed to one another and extend along a planar direction. The opposite ends of the spring member are connected respectively to the first and second slide members. Movement of the first and second slide members to a first position causes the spring member to possess a restoration force that is capable of retaining the first and second slide members at a second position different from the first position.
