Claim:
A conjunctive structure comprising: a baseboard, a hole being formed that penetrates completely through the baseboard; a peripheral element comprising a bulge, wherein a shape and a size of the bulge are compatible to the hole in the baseboard; a connecting apparatus comprising: at least one first magnetic connecting element placed on at least one corner of the peripheral element; at least one second magnetic connecting element placed around the hole of the baseboard corresponding to the at least one first magnetic connecting element, wherein the at least one second magnetic connecting element comprises two adjacent magnetic elements with opposite polarity arrangement; a supporting board placed parallel with the baseboard; and a plurality of elastic elements for connecting the supporting board and the baseboard, wherein when the peripheral element is connected to the baseboard such that the bulge of the peripheral element is pushed into the hole of the baseboard, the at least one first magnetic connecting element and the at least one second magnetic connecting element attract each other, and when the peripheral element is pushed transversely to be separated from the baseboard, at least one first magnetic connecting element and the at least one second magnetic connecting element repulse each other.
