Claim 9:
10. A board-to-board assembled structure comprising:
a first board, having a first surface, a second surface opposite to the first surface and a through hole passing through the first surface and the second surface;
a second board, facing the second surface of the first board and having an insertion hole corresponding to the through hole; and
a fastening assembly, comprising:
a first sleeve, comprising a plug tube connected to a bottom surface of the first sleeve, wherein the plug tube has a passage communicating with the first sleeve;
a second sleeve, integrated into the first sleeve to form an accommodating space communicating with the passage;
a driven element, disposed in the accommodating space and comprising a guiding portion and an inserting rod, wherein the inserting rod is movably inserted in the passage along a first direction, and the guiding portion has a first inclined guiding surface forming a first acute angle with the first direction;
a positioning element, comprising:
a guide rod, movably inserted in the second sleeve along a second direction that forms a second acute angle with the first inclined guiding surface; and
a slide block, connected to the guide rod and in sliding contact with the first inclined guiding surface; and

an elastic element, disposed in the accommodating space and allowing the inserting rod axially inserted therein, wherein one end of the elastic element leans against the driven element, and the other end of the elastic element leans against the first sleeve;
wherein a portion of the plug tube passes through the through hole from the first surface and clamped on the second surface;
when the positioning element is pushed by an external force to drive the guide rod moving along the second direction in the second sleeve, the driven element is driven to move along the first direction, so as to make the inserting rod passing through the passage and entering into the insertion hole;
when the external force is removed, the driven element is pushed by the elastic element to drive the guide rod in the second sleeve moving along a direction opposite to the second direction, so as to make the plunger moving along a direction opposite to the first direction and leaves the insertion hole.
